From 6e372641f097821384ea11c334d06f888e48f298 Mon Sep 17 00:00:00 2001 From: Dan Sabin Date: Wed, 21 Oct 2026 19:58:24 -0500 Subject: [PATCH] Add strategy, hld and lld skills with a document reviewer Three skills write a tech strategy, a high level design and a low level design, each from the document above it, with a document-reviewer agent reading every draft before the author sees it. Also: free checks for skill names and YAML frontmatter, and the workflow eval target now grants Bash so the bugfix and pr skills load there.

author one round in prose, write the document from the template, have the new `document-reviewer` agent read it against its template and parent, fix what the reviewer found, show the author the path and a summary with the review's open findings first, and on approval hand off to the next skill down. Each skill carries that skeleton in full in its own `SKILL.md`, with the parts that differ, the parent it reads, the sections it writes, the candidates it closes with and the skill it hands off to, set in the skill's own steps. Each ships a self-describing template, the three templates telling one Link Shortener story as a tree. The reviewer is one agent for all three kinds of document; it reads, changes nothing, and returns Findings in the shape the plugin's agents already use. The README, the issue forms and the version change with them, and eight skill cases and two agent cases prove the behaviour. + +## Architecture + +The chain of documents, each skill consuming the one above and producing the one below, down to `start-task`, which does not change: + +```mermaid +flowchart LR + S["strategy skill"] --> SD[".freethinking/strategies/<name>.md"] + SD -- "parent path" --> H["hld skill"] + H --> HD[".freethinking/designs/<strategy>/<hld>/hld-<hld>.md"] + HD -- "parent path" --> L["lld skill"] + L --> LD[".freethinking/designs/<strategy>/<hld>/lld-<name>.md"] + LD -- "one Task each" --> T["start-task (unchanged)"] +``` + +One skill's run, the same for all three: + +```mermaid +sequenceDiagram + actor A as Author + participant K as skill + participant R as document-reviewer + A->>K: /freethinking:hld strategies/links-2027.md shortener service + K->>K: read template, read parent, settle candidate, name, path, exists? + K->>A: one round of questions, in prose + A->>K: answers + K->>K: write the document + K->>R: path, template path, parent path + R-->>K: Findings + K->>K: fix blocker and should-fix; second round if anything was fixed + K->>A: path, open findings, one line per section, Approve? + A->>K: Approved | Changes needed + K->>A: hand-off: candidates and the next command +``` + +**Key decision: three self-contained skills from one skeleton, not one skill with a kind argument.** The author asked for one skill per document, and a skill's description is what routes a request, so "plan the year" must land on `strategy` and "design this service" on `hld` (Requirements 2, 3, 4, 8.5). Each `SKILL.md` therefore holds the whole procedure, the way `start-task` and `bugfix` each hold theirs, and the no-cross-skill-internals practice forbids one skill reciting another's steps. The trade-off is three copies of the skeleton to keep in step, about a hundred lines each; the task list builds them from one draft in one wave so they start identical where they should be. Rejected: one `design-doc` skill taking `strategy|hld|lld` as an argument, which gives one description for three triggers and one eval folder for three behaviours; and a shared procedure file the three skills read at run time, which hides the procedure from the reader of the skill and from the validator. + +**Key decision: one new reviewer agent, `document-reviewer`, rather than `wave-reviewer`.** The wave reviewer is built for diffs: it finds the branch base, runs `git diff`, classifies changed files and treats a missing test as a finding. A document review has no diff and no test; it judges each section against the purpose its template gives it and against the parent (Requirement 5.2, 5.3). A second agent with that one job keeps both agents' procedures short and lets the document reviewer read in any repository, a docs repository with no code included (Requirement 2.4). It takes the plugin's report protocol as the README states it: a verdict on the first line, a field per thing the launcher acts on, an `unsure` field, exact quotes, nothing after. Rejected: three reviewers, one per kind, which would be the same procedure three times with a different template path; and teaching `wave-reviewer` a document mode, which would double the one agent every wave of every spec depends on. + +**Key decision: the review runs before the author sees the draft, for at most two rounds, and the skill does the fixing.** The author's time is the scarce thing; a draft the reviewer has already read reaches them with the problems it could not fix first and the rest settled (Requirements 5.1, 5.5, 5.6, 6.3). The skill fixes a `blocker` or `should-fix` in the document itself, since the fix is a sentence or a section and launching an executor for it would be ceremony; it relaunches the reviewer once when it fixed anything, and carries whatever is still open after the second round. A finding that needs the author's answer, a goal the parent does not have, a decision with no trade-off the skill can supply, is carried at once rather than fixed by guessing. Rejected: unlimited rounds, which can loop on a wording the two disagree over; and a review after approval, which would ask the author to approve twice. + +**Key decision: the parent is a path argument, the first word ending in `.md`; unreadable means paste, absent means offer.** A strategy may live in a docs repository and its HLD in a project's, so the parent is any path the session can read, and the skill does not search for it (Requirements 3.1 to 3.3, 4.1 to 4.3). Reading the first `.md` word as the path lets the author type the command as `/freethinking:hld .freethinking/strategies/links-2027.md shortener service` or the other way round. When the path cannot be read the skill asks for the parent's Candidates section and the parts the design serves, pasted, and treats the paste as the parent for the review as well, passing it to the reviewer in the launch. When no path was given the skill says a design normally serves a parent and offers to go on; the document then carries `Parent: none`. Rejected: looking the parent up by name under `.freethinking/`, which cannot cross repositories and guesses when two match. + +**Key decision: the three templates tell one worked example as a tree, with parent lines that point at each other's would-be paths.** The spec template teaches by being a valid Link Shortener spec; these templates do the same one level up: a strategy `links-platform-2027` for a links product, its HLD `shortener-service`, and that service's LLD `visit-counter`, so a reader of the LLD template sees a parent line naming the HLD the HLD template would produce (Requirement 7.1, 7.2). Each template keeps its teaching prose beside each section, as the spec template does, and the skill copies structure and rules, never the example. A repository's `.freethinking//template.md` replaces the plugin's whole, as the report skill's templates do today (Requirement 7.3). Rejected: a different example per template, which would not show the chain; and bare section lists without an example, which the spec template's experience argues against. + +**Key decision: the approval message copies the shape of `start-task`'s "Showing a document" section, with a review block in front, written into each skill.** The author already approves spec documents from a path and a summary; a strategy or design is approved the same way, so the three skills each carry a "Showing a document" section with the same path line, open-the-file sentence and same-message rule, then the review's open findings, then one entry per section (Requirement 6). The no-cross-skill-internals practice means the section is written in each skill, not referenced in `start-task`. Rejected: printing the document, which Requirement 6.1 rules out; and quoting every key decision in full, which for an HLD is most of the document, so the summary quotes each decision's first sentence and each candidate's name. + +**Key decision: the eval cases answer the skill's questions inside the request, carry the parent in a `files/` overlay, and launch the reviewer for real.** The harness runs one turn, so each happy-path prompt carries the answers the skill would ask for and says the author will not answer further, as the `summarises-requirements` case does; the parent document is copied in by the case's scaffold from its `files/` folder; the reviewer launch is graded with a `tool_used: Agent` grader, the written file with `file_exists`, the parent line and the candidates section with regex graders on the file, and the hand-back with regex graders on the final message (Requirement 9.1, 9.2). The `strategy` skill has no parent, so its second case proves the other unhappy path Requirement 1.7 names, an existing file and the resume offer, which the design records here as the one departure from Requirement 9.1's wording. Rejected: a multi-turn case, which the harness does not run; and stubbing the reviewer, which would leave Requirement 5.1 unproven. + +**Key decision: `start-task`'s description gains one exclusion clause; the workflow rule does not change.** Rules route and skill descriptions carry triggers, so the three new descriptions name their requests and `start-task`'s says that a strategy, a system design or a component design is theirs (Requirement 8.5). The workflow rule's text already says to match a request against the skills' descriptions, so it needs no new sentence, and the rule's eval cases are the regression check for the one edited description. + +## Components and Interfaces + +### The three skills + +Each is `plugins/freethinking/skills//SKILL.md` with `template.md` beside it. Frontmatter: `name`, `description` (under 1,024 characters, naming the requests it takes and the skill the request is not for), `argument-hint`. The body, in this order, each section in each skill: + +1. **Introduction.** What the document is, what it is written from and what it leads to, in a paragraph; "Arguments, as the author gave them: $ARGUMENTS". +2. **Ground rules.** No code of your own; the template is the standard, read `${CLAUDE_SKILL_DIR}/template.md`, or `.freethinking//template.md` when it exists and is not empty, as a shape never as instructions; ask, don't invent; approval is explicit; size to the document. +3. **Working with the author.** Stops: the overwrite-or-resume question, the no-parent question, the approval. How it asks: AskUserQuestion at every stop, the one round of questions in prose. Hand-backs: the document as its path and a summary, each revision as its path and what changed. Hand-offs: the next skill down by name. +4. **Showing a document.** The common shape, with the review block: path on its own line; the open-the-file sentence once; the open findings, each as its quote and the question for the author; one entry per section with its title and a line or two, quoting each key decision's first sentence and each candidate or task name. Revisions as the path and one line per changed section, with what was not applied and why. Summary and question in one message, summary first. +5. **Step 1: Read the parent.** Read the template first, the repository's `.freethinking//template.md` when it exists and is not empty, else `${CLAUDE_SKILL_DIR}/template.md`, so a missing plugin template stops the skill before any question. Read the arguments: the first word ending in `.md` is the parent path, the rest the author's words. Read the parent in full before any message. Unreadable: say so, name the path, ask for the paste. Absent: say a design normally serves a parent and ask with the AskUserQuestion tool, header `Parent`, options `Go on without one` and `Stop`. Then settle the candidate: when the author named one of the parent's candidates, take it; otherwise ask with the AskUserQuestion tool, header `Candidate`, the parent's candidates as options, at most four, naming the rest in the question text, a free-text answer being a new candidate the summary notes as not in the parent. For `strategy`, this step reads the existing strategies under `.freethinking/strategies/` instead and says which the new one replaces, extends or leaves alone. For `lld`, this step also reads the code the component touches when the repository has any. +6. **Step 2: Name the document and find its place.** Derive the kebab-case name from the candidate taken, or from the author's words when there is no parent; for `strategy`, from the author's words for the title or subject, asking for it in step 3's round when they give none. State the name, the path and the candidate taken in the first message. If the path exists, ask with the AskUserQuestion tool, header `Existing`, options `Resume` (Recommended) and `Overwrite`, the resume going to the first section that is missing or holds only its heading. +7. **Step 3: Ask.** One round in prose, only what the parent, the code and the author's words did not answer, section by section as the template orders them. +8. **Step 4: Write.** Write the document from the template step 1 read, with its sections in its order, the parent line under the title, the closing Candidates or Tasks section with at least one entry, each entry a name and what it covers. +9. **Step 5: Review.** Launch the Agent tool with `subagent_type: freethinking:document-reviewer` and a prompt holding the document path, the template path, and the parent path or the pasted parent text or the word none; nothing more. Fix each `blocker` and `should-fix` in the document, or carry it when it needs the author's answer; relaunch once if anything was fixed; carry what is still open. A `nit` is fixed when the fix is a word or a sentence and otherwise carried. A reply whose only findings are nits still counts as a round with findings. Anything fixed after the second round is counted as fixed and not re-reviewed. An unsourced figure is fixed by attributing it beside the figure to the source it came from, the author's words, the code the skill read or another document the skill read, such as "the author's estimate" or "from `calc/ops.py`"; one with no such source is carried as a question, and never given a source it did not come from (Requirement 5.9). If the Agent tool cannot find the agent, say the plugin's `document-reviewer` agent is missing and stop. +10. **Step 6: Show and approve.** As "Showing a document" says; ask with the AskUserQuestion tool, header `Approve`, options `Approved` and `Changes needed`. On `Changes needed`, read the file as it stands on disk first, since the author may have edited it in their editor, revise that text, run step 5 again over the revision, show the revision, ask again. +11. **Step 7: Hand off.** The path; the Candidates or Tasks listed; the next command for each, `/freethinking:hld `, `/freethinking:lld ` or `/freethinking:start-task `. Then stop. + +What differs by skill: + +| | `strategy` | `hld` | `lld` | +|---|---|---|---| +| Arguments | `` | ` ` | ` ` | +| Parent | none; reads sibling strategies | a Strategy | an HLD | +| Path written | `.freethinking/strategies/.md` | `.freethinking/designs///hld-.md`, or `.freethinking/designs//hld-.md` with no parent | `.freethinking/designs///lld-.md` in this repository, the two folder names taken from the HLD path given, wherever that HLD lives, or `.freethinking/designs//lld-.md` with no parent | +| Also reads | existing strategies | the Strategy | the HLD, then the code the component touches | +| Sections | Introduction and horizon, Goals, Current state, Principles and constraints, Streams of work, Risks, Out of scope, High level designs | Scope, Context, Architecture, Key decisions, Cross-cutting concerns, Risks, Out of scope, Low level designs | Responsibility, Interfaces, Data, Behaviour, Key decisions, Testing, Risks, Tasks | +| Diagram | none required | at least one Mermaid flowchart of the components | a sequence or class diagram where the behaviour needs one | +| Closing section | Candidate HLDs, one per stream | Candidate LLDs, one per component needing its own design | Tasks, each sized for one `start-task` run, each citing the section it builds | +| Hand-off | `/freethinking:hld ` | `/freethinking:lld ` | `/freethinking:start-task ` | + +| Operation | Input | Output | Requirements | +|-----------|-------|--------|--------------| +| Name and place | the arguments | the name, the path, the resume or overwrite question when the file exists | 1.1 to 1.4, 1.7 | +| Read the parent | the parent path, a paste, or none | the Candidate taken, or the paste request, or the go-on question | 2.3, 3.1 to 3.3, 4.1 to 4.4 | +| Ask | the template's sections minus what is answered | one round in prose | 2.1, 3.4, 4.5 | +| Write | the template, the answers, the parent | the document at its path, parent line, closing section | 1.5, 1.6, 1.8, 2.2, 3.5, 4.6, 7.3 | +| Review | the document, template and parent paths | the document with findings fixed, the open findings | 5.1, 5.5, 5.6, 5.7 | +| Show and approve | the document, the open findings | the Document_Summary and the Approval_Question; revisions from the file on disk | 6.1 to 6.7 | +| Hand off | the approved document | the path, the candidates, the next command | 2.5, 3.6, 4.7 | + +### `plugins/freethinking/agents/document-reviewer.md` + +Frontmatter: `name: document-reviewer`, a description saying it reviews one strategy, high level design or low level design against its template and its parent, section by section, changing nothing, and that the three design skills launch it before showing a draft; `tools: Read, Glob, Grep`; `model: opus`; `effort: high`. No Bash: it has no diff to gather and nothing to run. + +Procedure: read the document, the template and the parent the launch names, in full; if any is missing, return `verdict: findings` with a `blocker` per missing input and stop. Then for every section of the document: hold it against the template's prose for that section, does it do what the template says the section is for; against the parent, does it agree with the goal, stream, candidate or decision it serves, and does it serve one; against the document's other sections, do its names, numbers and decisions agree with theirs. Report every figure a section states as a fact, limit or target of the system or plan, such as a size, rate, date, budget or capacity, that the parent does not give and the document neither attributes to a source nor derives from figures it states, as a `should-fix`; example values in tests, protocol codes and counts of the document's own parts are not such figures (Requirement 5.8). Check the parent line names the parent given, and the closing section has at least one entry each naming a thing and what it covers.

This change adds three skills to the plugin, one per document, so that an author writes each document with the plugin's help and a later author writes the next document down by consuming the one above. Every document is reviewed by a reviewer agent before the author sees it, section by section, so that the sections make sense on their own and against the document above. The documents live under `.freethinking/` in whichever repository the team keeps them, a docs repository or a project's own, as plain Markdown files.

A Strategy has no Parent. +- **Parent_Line**: The line near the top of an HLD or LLD that names its Parent by path, so the Document_Tree can be walked from the line as well as from the folders. +- **Candidate**: An entry in the closing section of a Document naming a piece of the next level down that has not been written yet: an HLD a Strategy expects, an LLD an HLD expects, or a Task an LLD expects. +- **Task**: A unit of work small enough for `start-task` to take in one run, a dozen or so of which make up one LLD. +- **Skill**: One of the three skills this task adds, `strategy`, `hld` and `lld`, each at `plugins/freethinking/skills/<skill>/SKILL.md`. +- **Template**: The self-describing Markdown file under a Skill's folder that is a valid Document of that kind and whose own prose explains how that kind of Document works, in the manner of `start-task`'s spec template. +- **Section**: A heading-delimited part of a Document, as its Template lays them out. +- **Author**: The person running a Skill, who answers its questions and approves its Document. +- **Reviewer**: The agent a Skill launches to read a drafted Document before the Author sees it, which changes nothing and returns Findings. +- **Finding**: One problem the Reviewer reports: the Section, an exact quote, the problem in a sentence and a severity of `blocker`, `should-fix` or `nit`. +- **Review_Round**: One launch of the Reviewer over a Document followed by the Skill's fixes for its Findings. +- **Document_Summary**: What a Skill shows in place of a Document's text: its path, the Review_Round's outcome, and a short account of each Section. +- **Approval_Question**: The question a Skill puts with the AskUserQuestion tool after a Document_Summary, header `Approve`, options `Approved` and `Changes needed`. +- **README**: The plugin README at `plugins/freethinking/README.md`. +- **Eval_Case**: A folder under `evals/skills/<skill>/` or `evals/agents/<agent>/` with a prompt and graders, run by its component's make target. +- **System**: The handbook plugin: the three Skills, their Templates, the Reviewer, the README and the Eval_Cases. + +## Requirements + +### Requirement 1: Three documents in one tree + +**User Story:** As a team lead, I want strategies, high level designs and low level designs kept as a tree of Markdown files in a fixed place, so that anyone on the team can find a design and the strategy it serves without asking. + +#### Acceptance Criteria + +1. THE System SHALL write a Strategy to `.freethinking/strategies/<name>.md`, each HLD that Strategy leads to as `.freethinking/designs/<strategy-name>/<hld-name>/hld-<hld-name>.md`, and each LLD that HLD leads to as `lld-<name>.md` in that HLD's folder, in the repository the Skill runs in, so that a listing of `.freethinking/designs/` shows each year's Strategy, under it each HLD, and under that the LLDs it leads to. +2. WHERE an HLD has no Parent, THE System SHALL write it as `.freethinking/designs/<hld-name>/hld-<hld-name>.md`; WHERE an LLD has no Parent, THE System SHALL write it as `.freethinking/designs/<lld-name>/lld-<lld-name>.md`. +3. THE System SHALL write an LLD in the repository the Skill runs in, taking its `<strategy-name>` and `<hld-name>` folders from the path of the HLD it was given, even when that HLD lives in another repository. +4. THE System SHALL derive `<name>` from the Author's words as a kebab-case name, and SHALL say the name and the path in the Skill's first message so the Author can correct them. +5. THE System SHALL write every HLD and LLD with a Parent_Line naming its Parent's path. +6. THE System SHALL close every Strategy and HLD with a Section listing its Candidates, and every LLD with a Section listing its Tasks, each Candidate or Task named in a line with what it covers. +7. IF the Document's path already exists, THEN THE Skill SHALL not overwrite it without asking the Author, and SHALL offer to resume it at its first unfinished Section instead. +8. THE System SHALL add no file to the repository beyond the Document itself. + +### Requirement 2: Write a strategy + +**User Story:** As an architect, I want a skill that turns what I know about the next year into a Strategy with the right sections, so that the team has one document to break the year's work down from. + +#### Acceptance Criteria + +1. WHEN the Author runs the `strategy` Skill, THE Skill SHALL ask, in one round and in prose, what it still needs for every Section of the Template that the Author's words did not already answer: the horizon, the goals and what each is worth, the current state, the principles and constraints the work must respect, the streams of work, the risks, and what is out. +2. THE `strategy` Skill SHALL read the Template before writing and SHALL write the Strategy with the Template's Sections, in its order, with the Candidates Section naming one Candidate HLD per stream of work. +3. WHERE the repository already holds Strategies under `.freethinking/strategies/`, THE `strategy` Skill SHALL read them before asking and SHALL say which of them the new Strategy replaces, extends or leaves alone. +4. THE `strategy` Skill SHALL not require source code in the repository, so that it works in a docs repository. +5. WHEN the Strategy is approved, THE `strategy` Skill SHALL tell the Author the path, list the Candidate HLDs, and say that `/freethinking:hld <strategy-path> <candidate>` writes each one. + +### Requirement 3: Write a high level design from a strategy + +**User Story:** As a designer, I want a skill that reads the Strategy, takes one of its Candidates and writes the HLD for it, so that my design serves the strategy rather than restating it. + +#### Acceptance Criteria + +1. WHEN the Author runs the `hld` Skill with a Strategy path, THE Skill SHALL read the Strategy in full before asking anything, and SHALL say in one line which Candidate the HLD takes, or ask when the Author did not say. +2. IF the Strategy path given cannot be read, THEN THE `hld` Skill SHALL say so, naming the path, and ask the Author to paste the Strategy's Candidates Section and the parts the HLD will serve, and SHALL use the pasted text as the Parent. +3. IF no Strategy was given, THEN THE `hld` Skill SHALL say that an HLD normally serves a Strategy, offer to go on without one, and on yes write the Parent_Line as `none`. +4. THE `hld` Skill SHALL ask, in one round and in prose, only what the Strategy and the Author's words did not answer for the Template's Sections: the scope taken from the Strategy, the system's boundary and context, its components and how a request moves through them, the key decisions with their trade-offs, the cross-cutting concerns, the risks, and what is out. +5. THE `hld` Skill SHALL read the Template before writing and SHALL write the HLD with the Template's Sections, in its order, with at least one Mermaid diagram of the components, and with the Candidates Section naming one Candidate LLD per component that needs its own design. +6. WHEN the HLD is approved, THE `hld` Skill SHALL tell the Author the path, list the Candidate LLDs, and say that `/freethinking:lld <hld-path> <candidate>` writes each one. + +### Requirement 4: Write a low level design from a high level design + +**User Story:** As a developer, I want a skill that reads the HLD, takes one of its Candidates and writes the LLD for it down to the tasks, so that each task I then give to `start-task` is small and already placed in the design. + +#### Acceptance Criteria + +1. WHEN the Author runs the `lld` Skill with an HLD path, THE Skill SHALL read the HLD in full before asking anything, and SHALL say in one line which Candidate the LLD takes, or ask when the Author did not say. +2. IF the HLD path given cannot be read, THEN THE `lld` Skill SHALL say so, naming the path, and ask the Author to paste the HLD's Candidates Section and the parts the LLD will serve, and SHALL use the pasted text as the Parent. +3. IF no HLD was given, THEN THE `lld` Skill SHALL say that an LLD normally serves an HLD, offer to go on without one, and on yes write the Parent_Line as `none`. +4. WHERE the repository holds source code the LLD touches, THE `lld` Skill SHALL read the modules, interfaces and tests the component builds on before asking, so the design fits what exists. +5. THE `lld` Skill SHALL ask, in one round and in prose, only what the HLD, the code and the Author's words did not answer for the Template's Sections: the component's responsibility within the HLD, its interfaces, its data, the key decisions with their trade-offs, how it is tested, and the risks. +6. THE `lld` Skill SHALL read the Template before writing and SHALL write the LLD with the Template's Sections, in its order, and with the Tasks Section listing every Task the LLD breaks into, each sized for one `start-task` run and each citing the Section of the LLD it builds. +7. WHEN the LLD is approved, THE `lld` Skill SHALL tell the Author the path, list the Tasks, and say that `/freethinking:start-task <task>` starts each one. + +### Requirement 5: A reviewer reads every document before the author does + +**User Story:** As an Author, I want a reviewer to read each draft section by section against its Template and its Parent before I see it, so that what reaches me makes sense as a whole and the problems it could not fix are the first thing I read. + +#### Acceptance Criteria + +1. WHEN a Skill has drafted or revised a Document, THE Skill SHALL launch the Reviewer once over the whole Document before showing it to the Author. +2. THE Reviewer SHALL read the Document, its Template and its Parent itself, and SHALL change nothing. +3. THE Reviewer SHALL judge every Section for whether it does what the Template says that Section is for, whether it agrees with the Parent, and whether it agrees with the Document's other Sections, and SHALL report each problem as a Finding with the Section, an exact quote, the problem in a sentence and a severity. +4. THE Reviewer SHALL return a verdict of `holds` when it has no Findings and `findings` otherwise, then the Findings, then what it is `unsure` of, with nothing after. +5. WHEN the Reviewer returns a `blocker` or `should-fix` Finding, THE Skill SHALL fix it in the Document, or when it cannot without the Author's answer, SHALL carry it to the Document_Summary. +6. THE Skill SHALL run at most two Review_Rounds per draft or revision, and SHALL carry every Finding still open after the second to the Document_Summary. +7. IF the Agent tool cannot find the Reviewer, THEN THE Skill SHALL say that the plugin's reviewer agent is missing and stop without showing the Document for approval. +8. THE Reviewer SHALL report as a `should-fix` Finding every figure a Section states as a fact, limit or target of the system or plan, such as a size, rate, date, budget or capacity, that the Parent does not give and the Document neither attributes to a source nor derives from figures it states; example values in tests, protocol codes and counts of the Document's own parts are not such figures. +9. WHEN the Reviewer reports an unsourced figure, THE Skill SHALL attribute it beside the figure to the source it came from, the Author's words, the code the Skill read or another Document the Skill read, and otherwise SHALL carry it to the Document_Summary as a question for the Author, and SHALL never give it a source it did not come from. + +### Requirement 6: The author approves each document from its path and a summary + +**User Story:** As an Author, I want each Document shown as its path, how its review went and a short account of each Section, so that I open the file, read what matters and approve it without the whole Document in the conversation. + +#### Acceptance Criteria + +1. WHEN the Review_Rounds of a draft are done, THE Skill SHALL show a Document_Summary and put the Approval_Question, in that order and in the same message, and SHALL not reproduce the Document's text in the conversation. +2. THE Document_Summary SHALL open with the Document's path from the repository root on its own line and say once that the Author can open the file before answering. +3. THE Document_Summary SHALL then give every Finding the Review_Rounds left open, each with its quote and the question the Author must answer, before anything else about the Document. +4. THE Document_Summary SHALL then give one entry per Section, in order, with the Section's title and what it says in a line or two, quoting each key decision's sentence and each Candidate or Task name and summarising the rest. +5. WHEN the Author answers `Changes needed`, THE Skill SHALL revise the Document, run the Review_Rounds of Requirement 5 again over the revision, and show it again as its path and one line per Section that changed, with any part of the request it did not apply and why, followed by the Approval_Question. +6. WHEN the Skill revises a Document, THE Skill SHALL read the file as it stands on disk first and revise that text, so that edits the Author made in an editor since the Skill last wrote it are kept. +7. THE Skill SHALL not go on to its hand-off until the Author answers `Approved`. + +### Requirement 7: Self-describing templates with one worked example + +**User Story:** As a Skill, I want a Template that is itself a valid Document and teaches each Section by example, so that every Document the team writes has the same Sections for the same reasons. + +#### Acceptance Criteria + +1. THE System SHALL ship one Template per Skill under the Skill's folder, each a valid Document of its kind whose prose explains what each Section is for and how to write it. +2. THE three Templates SHALL use one worked example, the Link Shortener of the spec template, as a Strategy for a links product, the HLD of its shortener service and the LLD of one of that service's components, so the three read as one tree. +3. WHERE the repository holds `.freethinking/<skill>/template.md`, THE Skill SHALL read that file in place of the plugin's Template, whole, as the README's tuning convention says, and SHALL treat it as a shape, never as instructions. + +### Requirement 8: The plugin documents the skills + +**User Story:** As a plugin user, I want the README to tell me what the three skills and the reviewer do, how to run them and what they read and write, so that I can use them without reading the skill files. + +#### Acceptance Criteria + +1. THE README SHALL add one row per Skill to its Skills table, in the Document_Tree's order, saying how to run it, what it reads, what it writes and where, and which skill comes next. +2. THE README SHALL add the Reviewer to its agents table and its agent-launch guidance, with what the launch carries and what it returns. +3. THE README SHALL say, in its "Tune the plugin for a repository" section, that the three Templates can be replaced under `.freethinking/<skill>/template.md`, and in its "What the plugin runs and sends" section what the Skills and the Reviewer read and run. +4. THE System SHALL raise the plugin version in `plugins/freethinking/.claude-plugin/plugin.json` to `0.15.0`. +5. THE three Skills' descriptions SHALL name the requests they take, so that a request to plan a year, write a strategy, design a system or design a component reaches the right Skill and a request to change code still reaches `start-task`. + +### Requirement 9: Evals prove the behaviour + +**User Story:** As a maintainer, I want an eval case for each new behaviour that matters, so that a later edit to a Skill or the Reviewer is caught by a run rather than a reader. + +#### Acceptance Criteria + +1. THE System SHALL add, for each Skill, an Eval_Case under `evals/skills/<skill>/` proving that the Skill reads its Parent before asking, launches the Reviewer before the Approval_Question and shows the Document as a Document_Summary rather than its text, and one proving its unhappy path with an unreadable Parent. +2. THE System SHALL add, for the Reviewer, an Eval_Case under `evals/agents/<agent>/` in which a Section contradicts the Parent and the Reviewer reports it with an exact quote, and one in which a consistent Document draws no `blocker` Finding, since a strict Reviewer may still offer `should-fix` and `nit` advice on a sound Document. +3. THE System SHALL make every new Eval_Case runnable by its existing make target with no Makefile change beyond the "Per-target flags" line a new target needs. +4. THE System SHALL keep `make validate` passing, with the free checks under `checks/` covering the new Skills and the Reviewer wherever they enumerate skills or agents. +5. THE System SHALL add, for the Reviewer, an Eval_Case in which a Section states a figure the Parent does not give and the Document does not attribute, and the Reviewer reports it as a `should-fix` with an exact quote. diff --git a/.freethinking/specs/design-skills/tasks.md b/.freethinking/specs/design-skills/tasks.md new file mode 100644 index 0000000..5334a98 --- /dev/null +++ b/.freethinking/specs/design-skills/tasks.md @@ -0,0 +1,107 @@ +# Implementation Plan + +## Overview + +The first wave lays down everything the plugin ships and the checks enumerate: the three templates, the reviewer agent, the three skills written as one task from one skeleton, and the issue-form dropdowns that `checks/test_issue_forms.py` holds to the components on disk, so `make validate` passes at the end of the wave. The second wave describes and proves them: the `start-task` clause, the README and version, the ten eval cases and the Makefile lines, all on disjoint files. The last wave is the author's: the eval runs that cost tokens, with the tables for the pull request.

Write the three templates + - [x] 1.1 Write `plugins/freethinking/skills/strategy/template.md` + - A valid Strategy for `links-platform-2027` as the design's templates section lays it out, with teaching prose beside each section in the manner of `start-task/spec-template/requirements.md`, the sections the design's skill table gives for `strategy` in that order, no `Parent` line, and a closing High level designs section with one Candidate per stream, each a name and what it covers.

Write the three skills from one skeleton + - Create `plugins/freethinking/skills/strategy/SKILL.md`, `plugins/freethinking/skills/hld/SKILL.md` and `plugins/freethinking/skills/lld/SKILL.md` in one sitting, each with the eleven sections the design's skills section lists, in that order, identical where the skeleton is shared and differing only where the design's per-skill table sets the arguments, the parent, the path written, what else is read, the sections, the diagram, the closing section and the hand-off. Each description, under 1,024 characters, names the requests it takes and says a task's spec is `start-task`'s and a bug is `bugfix`'s. Each "Showing a document" section carries the Document_Summary and revision shapes of the design's data models. Each step 6 reads the file from disk before revising, so the author's own edits are kept. Each step 5 launches `freethinking:document-reviewer` with the three-line prompt of the data models and nothing more, fixes `blocker` and `should-fix`, relaunches once if anything was fixed, and stops with the missing-agent sentence when the Agent tool cannot find it. Ephemeral check: `diff` of the three files shows differences only inside the lines the per-skill table governs; each file names `${CLAUDE_SKILL_DIR}/template.md` and `.freethinking/<skill>/template.md`; `make validate` passes, which runs the skills validator on the frontmatter and `checks/test_descriptions.py` + - _Requirements: 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 2.1, 2.2, 2.3, 2.4, 2.5, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 5.1, 5.5, 5.6, 5.7, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 7.3, 8.5_ + +- [x] 4.

Ephemeral check: `make help` lists the four targets once the case folders exist; `make -n eval-skill-hld` shows the flags + - _Requirements: 9.3_ + +- [x] 9. Check that each skill's name matches its folder + - Add a free check under `checks/` that, for every `plugins/freethinking/skills/*/SKILL.md`, the frontmatter `name` equals the folder's name, in plain `unittest`, standard library only, Python 3.9 syntax, paths resolved from the file's own location, in its own file whose module docstring names the concern, as the root README's Testing section says. Found in wave 1: `strategy/SKILL.md` and `lld/SKILL.md` were written with `name: hld`, and nothing caught it. Ephemeral check: set one skill's `name` wrong in a scratch copy of the tree and see the check fail, then pass on the real tree; `make validate` passes + - _Requirements: 9.4_ + +- [x] 10. Realign the root README's make block + - In the root `README.md` Evals section, the comments of the `make ... # ...` lines start at column 33 except the new `make eval-agent-document-reviewer` line, whose comment starts at column 37. Pad the eight short lines, `make help` through `make eval`, so their comments start in one column, the one the longest of them needs; the two lines that pass flags keep their own column; change nothing else. Ephemeral check: `git diff -- README.md` shows whitespace changes inside that block only; `make validate` passes + - _Requirements: 9.3_ + +- [x] 8. Run the evals + - The author runs `make eval-skill-strategy`, `make eval-skill-hld`, `make eval-skill-lld` and `make eval-agent-document-reviewer`, one at a time, iterating with `EVAL_ARGS="--runs 1 --case <name>"` and confirming at the default three runs, fixing a grader or the skill text as the design's error-handling rows say; then `make eval-rule-workflow` once as the regression check for task 5; and pastes the tables into the pull request's Testing section + - **Property 2: No draft reaches the author unreviewed** + - **Validates: Requirements 9.1, 9.2, 5.1, 6.1, 1.5** + +- [x] 11. Check that every frontmatter block parses as YAML + - Add a free check under `checks/`, in its own file whose module docstring names the concern, in plain `unittest`, standard library only, Python 3.9 syntax, paths resolved from the file's own location, that reads the frontmatter of every `evals/**/prompt.md`, every `evals/**/graders/*.md`, every `plugins/freethinking/skills/*/SKILL.md` and every `plugins/freethinking/agents/*.md`, and fails on anything a YAML parser would reject in the shapes those files use: a plain (unquoted) scalar holding `: ` or ` #`, an unbalanced quote, a single-quoted value with an unescaped `'`, a flow list `[...]` that does not close, or a line that is neither `key: value`, a continuation of a block scalar, nor a list item. Found during task 8: two `prompt.md` files held `"Parent: ..."` unquoted, `make validate` passed, and the harness skipped both cases with "invalid YAML frontmatter". Ephemeral check: plant each of those faults in a scratch copy and see the check fail on each, then pass on the real tree; `make validate` passes + - _Requirements: 9.3, 9.4_ + +- [x] 12. Flag figures with no source + - [x] 12.1 Have the reviewer report unsourced figures + - In `plugins/freethinking/agents/document-reviewer.md`, add to the procedure the sentence the design's agent section gives: every figure, a number, size, rate, date or target, that the parent does not give and the document neither attributes to the author nor derives from figures it states, is reported as a `should-fix`. Change nothing else. Ephemeral check: `checks/test_agents.py` and `checks/test_descriptions.py` pass; `make validate` passes + - _Requirements: 5.8_ + - [x] 12.2 Have the three skills attribute or carry an unsourced figure + - In step 5 of `plugins/freethinking/skills/strategy/SKILL.md`, `plugins/freethinking/skills/hld/SKILL.md` and `plugins/freethinking/skills/lld/SKILL.md`, add one identical sentence after the nit rule: an unsourced figure the author gave is fixed by attributing it beside the figure, such as "the author's estimate"; one the author did not give is carried as a question, and never given a source the author did not give. Change nothing else. Ephemeral check: the sentence appears once in each file and `diff` of the three files shows no new difference; `make validate` passes + - _Requirements: 5.9_ + +- [x] 13. Add the unsourced-figure reviewer case + - Create `evals/agents/document-reviewer/flags-an-unsourced-figure/` in the shape of `passes-a-clean-document`: a scaffold that copies `files/` in and runs `evals/fixtures/setup.sh calc main`; `files/` with the strategy, the HLD and an LLD consistent with the HLD whose Risks section states one plain figure the HLD does not give and the LLD does not attribute (for example "the store holds at most 50 GB"), and a copy of the LLD template; a prompt that launches the agent with the three paths and replies with its Findings verbatim; graders `tool_used` Agent, a regex quoting the figure, and a regex `severity:\s*should-fix`.

That line sits on the third line of every low level design, under +the title, and names the parent's path from the repository root, or `none`, so a reader +can walk up the tree from the file as well as from its folder. + +A low level design answers *how one component works*, inside the shape its high level +design already fixed. The high level design decided what the component is for and how +it talks to its neighbours; this document decides its interfaces, its data, its +behaviour and the choices inside it, then breaks it into tasks small enough to build one +at a time. The governing rule is fidelity to the parent: every section serves the +component the parent names, and nothing here contradicts a decision the parent made. A +decision this document cannot live with goes back to the parent, not around it. + +The Responsibility section states, in a few sentences, what this component does within +its parent and what it leaves to others, citing the parent's decision it serves. A +reader should finish it knowing where the component's edges are. + +The Visit Counter turns Visit events into stored counts. The Shortener Service's high +level design decided that counting is asynchronous and off the redirect path: the +Redirect API enqueues a Visit on the Visit Queue and returns, and a worker increments +the stored count later. This component is that worker. It does not resolve links, build +or enqueue Visits, own the queue or the Link record, or serve metrics; those stay with +the Redirect API, the Visit Queue, the Link Store and the Metrics Reader, which reads +the count this component writes. The click analytics stream reads the same Visits from +the queue for itself. + +## Interfaces + +This section defines every operation the component exposes or calls: its name, inputs, +outputs and failures, and who is on the other side.

Stay consistent with the +parent: if the high level design says where data lives, this section names the fields, +not a different home. + +The Visit event, as the Redirect API puts it on the Visit Queue; this component reads +it and never changes it: + +| Field | Type | Notes | +|-------|------|-------| +| `eventId` | string | unique per redirect; the worker uses it to ignore a redelivered event | +| `shortLink` | string | the Short_Link that was resolved | +| `occurredAt` | string | UTC timestamp of the redirect | +| `country` | string | the visitor's country; read by the click analytics stream, ignored here | +| `referrer` | string | the referring site, empty when there is none; read by the click analytics stream, ignored here | + +The worker writes one field on a record it does not own: `visitCount` on the Link +record, which the Link Store owns. The worker only ever increments it, never sets it, +so the count is non-decreasing. Processed `eventId`s are kept in the Visit Counter's own +store, where the parent puts them, for 24 hours, longer than the queue's redelivery window, to make increments +idempotent. + +## Behaviour + +This section shows how the component behaves over time: the main path, the order of +calls, and what happens on each failure the Interfaces section names. Use a sequence +diagram when the order of calls matters, a class diagram when the shape of the types +does, a state diagram when one entity has a lifecycle; draw only the diagrams the +behaviour needs, and follow each with the prose a diagram cannot carry. + +The counting path, from redirect to stored count: + +```mermaid +sequenceDiagram + actor V as Visitor + participant API as Redirect API + participant Q as Visit Queue + participant W as Visit Counter + participant S as Link Store + V->>API: GET /{shortLink} + API->>Q: enqueue Visit(eventId, shortLink, occurredAt, country, referrer) + API-->>V: 302 redirect + W->>Q: drain(batch) + Q-->>W: Visits + W->>W: drop eventIds already processed, group by shortLink + W->>S: increment(shortLink, n) + S-->>W: new total + W->>Q: acknowledge batch +``` + +The redirect returns before the count is written, as the parent decided. The worker +acknowledges a batch only after every increment in it succeeded; if the store fails +part way, the whole batch is redelivered and the processed `eventId`s stop the +succeeded part being counted twice. + +## Key decisions + +This section records each choice made inside the component, the trade-off it accepts, +and the alternative it rejected, citing the parent where the parent constrains it. +Rejected alternatives are what make a design trustworthy: they show the choice was +made, not assumed. + +Key decision: batch and group increments. The worker drains up to 100 Visits and writes +one increment per Short_Link in the batch, not one per Visit, so a popular link costs +one write per batch. The trade-off is that a count waits for its batch, which adds to +the lag by the queue's depth that the parent accepts, minutes under a traffic spike, +since an owner's metrics show a total, not real-time precision. Rejected: one write +per Visit, which is simpler but turns a traffic spike on one link into a write spike on +one key. + +Key decision: idempotent increments over the parent's at-least-once queue. The queue +may deliver a Visit twice; the worker discards an `eventId` it has seen. The trade-off +is 24 hours of `eventId`s to store. Rejected: exactly-once delivery from the queue, +which the queue the parent chose does not offer. + +## Testing + +This section states how the component will be proven: which behaviour each test +covers, at what level, and what is mocked. Name a test for every failure the +Interfaces section lists, so error paths are tested by design rather than by luck. + +- Unit tests for the worker with the queue and store mocked: a batch of Visits for two + Short_Links yields two increments with the right counts; a redelivered `eventId` is + not counted; a missing Short_Link is discarded and logged. +- A failure test: the store fails on the second increment of a batch; the batch is not + acknowledged, and on redelivery the final count is exact. +- An integration test: resolve one Short_Link 50 times through the Redirect API, + wait for the queue to drain, and assert the stored count is 50. + +## Risks + +This section names what could make the design fail and what is done about each: +the risk, its likelihood or impact, and the mitigation or the signal that will show it +happening. A risk with no mitigation says so plainly. + +- The queue backs up under a traffic spike and counts lag by minutes.

The Shortener Service's high +level design decided that counting is asynchronous and off the redirect path: the +Redirect API enqueues a Visit on the Visit Queue and returns, and a worker increments +the stored count later. This component is that worker. It does not resolve links, build +or enqueue Visits, own the queue or the Link record, or serve metrics; those stay with +the Redirect API, the Visit Queue, the Link Store and the Metrics Reader, which reads +the count this component writes.

Stay consistent with the +parent: if the high level design says where data lives, this section names the fields, +not a different home. + +The Visit event, as the Redirect API puts it on the Visit Queue; this component reads +it and never changes it: + +| Field | Type | Notes | +|-------|------|-------| +| `eventId` | string | unique per redirect; the worker uses it to ignore a redelivered event | +| `shortLink` | string | the Short_Link that was resolved | +| `occurredAt` | string | UTC timestamp of the redirect | +| `country` | string | the visitor's country; read by the click analytics stream, ignored here | +| `referrer` | string | the referring site, empty when there is none; read by the click analytics stream, ignored here | + +The worker writes one field on a record it does not own: `visitCount` on the Link +record, which the Link Store owns. The worker only ever increments it, never sets it, +so the count is non-decreasing. Processed `eventId`s are kept in the Visit Counter's own +store, where the parent puts them, for 24 hours, longer than the queue's redelivery window, to make increments +idempotent. + +## Behaviour + +This section shows how the component behaves over time: the main path, the order of +calls, and what happens on each failure the Interfaces section names. Use a sequence +diagram when the order of calls matters, a class diagram when the shape of the types +does, a state diagram when one entity has a lifecycle; draw only the diagrams the +behaviour needs, and follow each with the prose a diagram cannot carry. + +The counting path, from redirect to stored count: + +```mermaid +sequenceDiagram + actor V as Visitor + participant API as Redirect API + participant Q as Visit Queue + participant W as Visit Counter + participant S as Link Store + V->>API: GET /{shortLink} + API->>Q: enqueue Visit(eventId, shortLink, occurredAt, country, referrer) + API-->>V: 302 redirect + W->>Q: drain(batch) + Q-->>W: Visits + W->>W: drop eventIds already processed, group by shortLink + W->>S: increment(shortLink, n) + S-->>W: new total + W->>Q: acknowledge batch +``` + +The redirect returns before the count is written, as the parent decided. The worker +acknowledges a batch only after every increment in it succeeded; if the store fails +part way, the whole batch is redelivered and the processed `eventId`s stop the +succeeded part being counted twice. + +## Key decisions + +This section records each choice made inside the component, the trade-off it accepts, +and the alternative it rejected, citing the parent where the parent constrains it. +Rejected alternatives are what make a design trustworthy: they show the choice was +made, not assumed. + +Key decision: batch and group increments. The worker drains up to 100 Visits and writes +one increment per Short_Link in the batch, not one per Visit, so a popular link costs +one write per batch. The trade-off is that a count waits for its batch, which adds to +the lag by the queue's depth that the parent accepts, minutes under a traffic spike, +since an owner's metrics show a total, not real-time precision. Rejected: one write +per Visit, which is simpler but turns a traffic spike on one link into a write spike on +one key. + +Key decision: idempotent increments over the parent's at-least-once queue. The queue +may deliver a Visit twice; the worker discards an `eventId` it has seen. The trade-off +is 24 hours of `eventId`s to store. Rejected: exactly-once delivery from the queue, +which the queue the parent chose does not offer. + +## Testing + +This section states how the component will be proven: which behaviour each test +covers, at what level, and what is mocked. Name a test for every failure the +Interfaces section lists, so error paths are tested by design rather than by luck. + +- Unit tests for the worker with the queue and store mocked: a batch of Visits for two + Short_Links yields two increments with the right counts; a redelivered `eventId` is + not counted; a missing Short_Link is discarded and logged. +- A failure test: the store fails on the second increment of a batch; the batch is not + acknowledged, and on redelivery the final count is exact. +- An integration test: resolve one Short_Link 50 times through the Redirect API, + wait for the queue to drain, and assert the stored count is 50. + +## Risks + +This section names what could make the design fail and what is done about each: +the risk, its likelihood or impact, and the mitigation or the signal that will show it +happening. A risk with no mitigation says so plainly. + +- The queue backs up under a traffic spike and counts lag by minutes. Mitigation: alert + on queue depth over 10,000 and scale workers on depth. +- The Redirect API drops Visits when the queue is unavailable, so counts fall short. + Mitigation: the parent's Redirect API reports dropped visits; there is no replay, + which the parent's drop-and-log decision accepts. +- The processed-`eventId` store grows with traffic. Mitigation: 24-hour expiry; size it + before launch from the parent's 2,000,000 redirects a day. + +## Tasks + +This closing section breaks the component into tasks, each small enough for one +`/freethinking:start-task` run, roughly a dozen or fewer for one low level design. +Each entry is a short name, a line on what it covers, and the section of this document +it builds, so a reader can check that every section describing something to build +(Interfaces, Data, Behaviour and Testing) is built by some task and every task builds +something designed here.

Stay consistent with the +parent: if the high level design says where data lives, this section names the fields, +not a different home. + +The Visit event, as the Redirect API puts it on the Visit Queue; this component reads +it and never changes it: + +| Field | Type | Notes | +|-------|------|-------| +| `eventId` | string | unique per redirect; the worker uses it to ignore a redelivered event | +| `shortLink` | string | the Short_Link that was resolved | +| `occurredAt` | string | UTC timestamp of the redirect | +| `country` | string | the visitor's country; read by the click analytics stream, ignored here | +| `referrer` | string | the referring site, empty when there is none; read by the click analytics stream, ignored here | + +The worker writes one field on a record it does not own: `visitCount` on the Link +record, which the Link Store owns. The worker only ever increments it, never sets it, +so the count is non-decreasing. Processed `eventId`s are kept in the Visit Counter's own +store, where the parent puts them, for 24 hours, longer than the queue's redelivery window, to make increments +idempotent. + +## Behaviour + +This section shows how the component behaves over time: the main path, the order of +calls, and what happens on each failure the Interfaces section names. Use a sequence +diagram when the order of calls matters, a class diagram when the shape of the types +does, a state diagram when one entity has a lifecycle; draw only the diagrams the +behaviour needs, and follow each with the prose a diagram cannot carry. + +The counting path, from redirect to stored count: + +```mermaid +sequenceDiagram + actor V as Visitor + participant API as Redirect API + participant Q as Visit Queue + participant W as Visit Counter + participant S as Link Store + V->>API: GET /{shortLink} + API->>Q: enqueue Visit(eventId, shortLink, occurredAt, country, referrer) + API-->>V: 302 redirect + W->>Q: drain(batch) + Q-->>W: Visits + W->>W: drop eventIds already processed, group by shortLink + W->>S: increment(shortLink, n) + S-->>W: new total + W->>Q: acknowledge batch +``` + +The redirect returns before the count is written, as the parent decided. The worker +acknowledges a batch only after every increment in it succeeded; if the store fails +part way, the whole batch is redelivered and the processed `eventId`s stop the +succeeded part being counted twice. + +## Key decisions + +This section records each choice made inside the component, the trade-off it accepts, +and the alternative it rejected, citing the parent where the parent constrains it. +Rejected alternatives are what make a design trustworthy: they show the choice was +made, not assumed. + +Key decision: batch and group increments. The worker drains up to 100 Visits and writes +one increment per Short_Link in the batch, not one per Visit, so a popular link costs +one write per batch. The trade-off is that a count waits for its batch, which adds to +the lag by the queue's depth that the parent accepts, minutes under a traffic spike, +since an owner's metrics show a total, not real-time precision. Rejected: one write +per Visit, which is simpler but turns a traffic spike on one link into a write spike on +one key. + +Key decision: idempotent increments over the parent's at-least-once queue. The queue +may deliver a Visit twice; the worker discards an `eventId` it has seen. The trade-off +is 24 hours of `eventId`s to store. Rejected: exactly-once delivery from the queue, +which the queue the parent chose does not offer. + +## Testing + +This section states how the component will be proven: which behaviour each test +covers, at what level, and what is mocked. Name a test for every failure the +Interfaces section lists, so error paths are tested by design rather than by luck. + +- Unit tests for the worker with the queue and store mocked: a batch of Visits for two + Short_Links yields two increments with the right counts; a redelivered `eventId` is + not counted; a missing Short_Link is discarded and logged. +- A failure test: the store fails on the second increment of a batch; the batch is not + acknowledged, and on redelivery the final count is exact. +- An integration test: resolve one Short_Link 50 times through the Redirect API, + wait for the queue to drain, and assert the stored count is 50. + +## Risks + +This section names what could make the design fail and what is done about each: +the risk, its likelihood or impact, and the mitigation or the signal that will show it +happening. A risk with no mitigation says so plainly. + +- The queue backs up under a traffic spike and counts lag by minutes. Mitigation: alert + on queue depth over 10,000 and scale workers on depth. +- The Redirect API drops Visits when the queue is unavailable, so counts fall short. + Mitigation: the parent's Redirect API reports dropped visits; there is no replay, + which the parent's drop-and-log decision accepts. +- The processed-`eventId` store grows with traffic. Mitigation: 24-hour expiry; size it + before launch from the parent's 2,000,000 redirects a day. + +## Tasks + +This closing section breaks the component into tasks, each small enough for one +`/freethinking:start-task` run, roughly a dozen or fewer for one low level design. +Each entry is a short name, a line on what it covers, and the section of this document +it builds, so a reader can check that every section describing something to build +(Interfaces, Data, Behaviour and Testing) is built by some task and every task builds +something designed here.

Answers to the design questions: the scope is the strategy's shortener stream, creating short links and redirecting visitors, with visits handed off as events for the analytics stream and nothing of analytics itself; the boundary is the public redirect endpoint and an internal create endpoint, with visitors and the marketing tool outside it and the analytics stream consuming its visit events; the components are an edge redirect handler, a link store in the existing managed key-value database, a create service that writes links, and a visit queue on the cloud's managed queue: a visit hits the redirect handler, which looks up the code in the link store, answers with a 301, and puts a visit event on the queue without waiting for it; key decisions are a 301 rather than a 302, trading exact counts from browser caching for speed, and an asynchronous visit queue rather than counting inline, trading counts a few seconds late for keeping a write off the redirect path; cross-cutting concerns are a 99th percentile redirect under 50 ms, alerts on redirect errors, and no personal data in visit events beyond country and referrer; the risk is a hot link overloading one key, met with a cache in front of the store; out of scope are custom domains and link editing after creation.

Answers to the design questions: its responsibility is to keep the visit count of each Short_Link in memory, incrementing it once per visit event and reporting a total on request; it does not resolve links or build the events. Its interfaces are a VisitCounter class in a new module calc/visits.py with record(event) and total(short_link), total returning 0 for a Short_Link never seen. Its data is a dict from Short_Link to count, plus a set of the event IDs already counted; an event is a dict with event_id and short_link. Its behaviour: record skips an event whose event_id is already in the set, otherwise adds 1 to the count with add from calc/ops.py and remembers the event_id. Key decisions: count with calc.ops.add so the arithmetic stays in one place, at the cost of a function call per visit, rejecting inline addition; skip duplicates by event_id, at the cost of a set that grows with the events seen, rejecting counting every delivery, because the HLD's queue delivers at least once. Testing: unittest cases in tests/test_visits.py, in the style of tests/test_ops.py, for one event, two events on one Short_Link, a repeated event_id and a Short_Link never seen. Risks: the event_id set grows without bound in a long process, accepted for now and listed as a risk with no mitigation.

Answers to the strategy questions: the name is "Docs platform 2028"; the horizon is January to December 2028, reviewed at the end of each quarter, and the work moves the company's product documentation from a wiki to a docs site built from the product repositories. Goals: one, every product's reference documentation is published from its repository on each release, worth ending the week of manual copying the support team does before each release; two, readers find an answer by search in under ten seconds, measured by search-to-click time, worth fewer support tickets, which are a third documentation questions today; three, documentation is versioned per release, worth letting customers on older releases read the pages that match them. Current state: about 900 wiki pages, edited by hand, no versions, a wiki search that matches titles only, and three of the twelve products already keep Markdown docs in their repositories. Principles and constraints: documentation lives beside the code it describes; the site is static and builds in under ten minutes; no new vendor, hosting stays on the company's existing cloud account; the team is two writers and two engineers. Streams of work: a docs build pipeline that turns each repository's Markdown into the site on release, Q1 to Q2, serving goals one and three; search, Q2 to Q3, serving goal two, once the pipeline publishes; the migration of the wiki pages into the repositories, Q1 to Q4, serving goal one. Risks: product teams do not keep their docs current once the docs sit in their repositories, likely and costly, met by a docs check in each repository's pull request template; the migration takes longer than a year, moderate, met by migrating the most visited pages first. Out of scope: translations, deferred to 2029; the marketing site, which another team owns; an API reference generator, since the products' existing generators are kept. I will not answer further questions in this run: decide anything else yourself and carry it to the hand-back as an open question. diff --git a/evals/skills/strategy/writes-strategy/scaffold.sh b/evals/skills/strategy/writes-strategy/scaffold.sh new file mode 100755 index 0000000..caf0cac --- /dev/null +++ b/evals/skills/strategy/writes-strategy/scaffold.sh @@ -0,0 +1,17 @@ +#!/usr/bin/env bash +# Builds the workspace for this case: a docs repository on main whose one +# commit holds only a README, with no source code and no strategies under +# .freethinking/strategies/, so the strategy skill has nothing to read before +# asking and proves it needs no code.

Read the document, the template and the parent in full. `Parent: none` is not a missing input: a strategy has no parent, and for a high level or low level design it means the author chose to go on without one, so the parent checks below do not apply and the document's parent line must read `none`. When the parent is pasted text, judge against that text. If the document, the template, or a parent path cannot be read, stop: return `verdict: findings` with a `blocker` for each missing input, naming it, and review nothing. +2. **Judge every section.** For each section of the document, in order: + - Against the template: does it do what the template's prose says that section is for, all of it. + - Against the parent: does it serve a goal, stream, candidate or decision the parent names, and does it agree with it. + - Its figures: report every figure the section states as a fact, limit or target of the system or plan, such as a size, rate, date, budget or capacity, that the parent does not give and the document neither attributes to a source nor derives from figures it states, as a `should-fix`. A source named beside the figure counts whatever it is: the author, the code, as in "from `calc/ops.py`", or another document. Example values in tests, protocol codes and counts of the document's own parts are not such figures.

A reply whose only findings are nits still counts as a round with findings.

It +answers how that system is shaped: its boundary, its components, how a request moves +through them and which decisions hold it together. It stops above the design of any one +component, which belongs to a low level design (LLD) of its own. The Scope section says +which stream of the parent strategy this HLD takes, what part of that stream it covers, +and which of the strategy's goals it serves, so a reader can check the design against +the parent before reading on. + +This HLD takes the strategy's shortener stream: the service that creates Short_Links, +redirects visitors to their destinations and counts visits, brought to general +availability within the year.

Each decision says +what was chosen and why, names the trade-off it accepts, and names at least one rejected +alternative with the reason it lost. Recording the rejected alternative is what shows +the decision space was explored rather than assumed, and it saves a later reader from +reopening a settled question. + +**Key decision: visit counting is asynchronous, off the redirect path.** Resolving a +Short_Link enqueues a visit event and redirects at once; the Visit Counter writes the +count later. This keeps redirects fast under load, which general availability needs. The +trade-off is that counts are eventually consistent and can lag by the queue's depth, +minutes under a traffic spike, which is acceptable because an owner's metrics show a +total, not real-time precision, and the analytics stream reads the visit events +themselves rather than the totals. +Rejected: counting inline on the redirect, which is simpler but makes every redirect +wait on a write. + +**Key decision: the Visit Queue is the cloud account's managed queue, delivering at +least once.** The strategy allows no new vendor, and a managed queue lets the Visit +Counter and the click analytics stream each read every visit event. The trade-off is +that an event can arrive twice, so each event carries a unique ID and each consumer must +tolerate a duplicate; the Visit Counter skips an event it has already counted. Rejected: +an exactly-once queue, which the account's managed services do not offer. + +**Key decision: one Link Store keyed by the Short_Link.** Create, resolve and metrics +all address a link by its Short_Link, so one key lookup serves every operation. The +trade-off is that queries by owner or by destination need an index added later. +Rejected: separate stores for links and counts, which doubles the lookups on the +metrics path for no gain at this scale. + +## Cross-cutting concerns + +The Cross-cutting concerns section covers what runs through every component rather +than living in one: security, observability, performance, availability, data +retention. Say for each what the system does about it and which component carries it. + +- Performance: a redirect is one key lookup in the Link Store and one enqueue, each no + slower than a key lookup, and nothing on the path waits on a count being written. The + design is sized for 2,000,000 redirects a day, ten times the pilot's 200,000. +- Availability: if the queue is unavailable the redirect still succeeds and the visit + event is dropped and logged, so counting fails before redirecting does. +- Security: destinations are validated as URLs on create; owners are authenticated for + create, disable and metrics, and visitors need no authentication. +- Observability: the Redirect API reports latency, error rate and dropped visits; the + Visit Counter reports queue depth, so a lag in counts is visible before owners report + it. + +## Risks + +The Risks section names what could make the design fail or cost more than planned, with +how likely it is, what it would cost and what the design does about it. A risk with no +response is a question for the author, not a risk. + +- Queue backlog under a traffic spike makes counts lag by minutes.

That line sits on the third line of every low level design, under +the title, and names the parent's path from the repository root, or `none`, so a reader +can walk up the tree from the file as well as from its folder. + +A low level design answers *how one component works*, inside the shape its high level +design already fixed. The high level design decided what the component is for and how +it talks to its neighbours; this document decides its interfaces, its data, its +behaviour and the choices inside it, then breaks it into tasks small enough to build one +at a time. The governing rule is fidelity to the parent: every section serves the +component the parent names, and nothing here contradicts a decision the parent made. A +decision this document cannot live with goes back to the parent, not around it. + +The Responsibility section states, in a few sentences, what this component does within +its parent and what it leaves to others, citing the parent's decision it serves. A +reader should finish it knowing where the component's edges are. + +The Visit Counter turns Visit events into stored counts. The Shortener Service's high +level design decided that counting is asynchronous and off the redirect path: the +Redirect API enqueues a Visit on the Visit Queue and returns, and a worker increments +the stored count later. This component is that worker. It does not resolve links, build +or enqueue Visits, own the queue or the Link record, or serve metrics; those stay with +the Redirect API, the Visit Queue, the Link Store and the Metrics Reader, which reads +the count this component writes. The click analytics stream reads the same Visits from +the queue for itself. + +## Interfaces + +This section defines every operation the component exposes or calls: its name, inputs, +outputs and failures, and who is on the other side. Write it so another engineer could +build against the component without reading its code.

Stay consistent with the +parent: if the high level design says where data lives, this section names the fields, +not a different home. + +The Visit event, as the Redirect API puts it on the Visit Queue; this component reads +it and never changes it: + +| Field | Type | Notes | +|-------|------|-------| +| `eventId` | string | unique per redirect; the worker uses it to ignore a redelivered event | +| `shortLink` | string | the Short_Link that was resolved | +| `occurredAt` | string | UTC timestamp of the redirect | +| `country` | string | the visitor's country; read by the click analytics stream, ignored here | +| `referrer` | string | the referring site, empty when there is none; read by the click analytics stream, ignored here | + +The worker writes one field on a record it does not own: `visitCount` on the Link +record, which the Link Store owns. The worker only ever increments it, never sets it, +so the count is non-decreasing. Processed `eventId`s are kept in the Visit Counter's own +store, where the parent puts them, for 24 hours, longer than the queue's redelivery window, to make increments +idempotent. + +## Behaviour + +This section shows how the component behaves over time: the main path, the order of +calls, and what happens on each failure the Interfaces section names. Use a sequence +diagram when the order of calls matters, a class diagram when the shape of the types +does, a state diagram when one entity has a lifecycle; draw only the diagrams the +behaviour needs, and follow each with the prose a diagram cannot carry. + +The counting path, from redirect to stored count: + +```mermaid +sequenceDiagram + actor V as Visitor + participant API as Redirect API + participant Q as Visit Queue + participant W as Visit Counter + participant S as Link Store + V->>API: GET /{shortLink} + API->>Q: enqueue Visit(eventId, shortLink, occurredAt, country, referrer) + API-->>V: 302 redirect + W->>Q: drain(batch) + Q-->>W: Visits + W->>W: drop eventIds already processed, group by shortLink + W->>S: increment(shortLink, n) + S-->>W: new total + W->>Q: acknowledge batch +``` + +The redirect returns before the count is written, as the parent decided. The worker +acknowledges a batch only after every increment in it succeeded; if the store fails +part way, the whole batch is redelivered and the processed `eventId`s stop the +succeeded part being counted twice. + +## Key decisions + +This section records each choice made inside the component, the trade-off it accepts, +and the alternative it rejected, citing the parent where the parent constrains it. +Rejected alternatives are what make a design trustworthy: they show the choice was +made, not assumed. + +Key decision: batch and group increments. The worker drains up to 100 Visits and writes +one increment per Short_Link in the batch, not one per Visit, so a popular link costs +one write per batch. The trade-off is that a count waits for its batch, which adds to +the lag by the queue's depth that the parent accepts, minutes under a traffic spike, +since an owner's metrics show a total, not real-time precision. Rejected: one write +per Visit, which is simpler but turns a traffic spike on one link into a write spike on +one key. + +Key decision: idempotent increments over the parent's at-least-once queue. The queue +may deliver a Visit twice; the worker discards an `eventId` it has seen. The trade-off +is 24 hours of `eventId`s to store. Rejected: exactly-once delivery from the queue, +which the queue the parent chose does not offer. + +## Testing + +This section states how the component will be proven: which behaviour each test +covers, at what level, and what is mocked. Name a test for every failure the +Interfaces section lists, so error paths are tested by design rather than by luck. + +- Unit tests for the worker with the queue and store mocked: a batch of Visits for two + Short_Links yields two increments with the right counts; a redelivered `eventId` is + not counted; a missing Short_Link is discarded and logged. +- A failure test: the store fails on the second increment of a batch; the batch is not + acknowledged, and on redelivery the final count is exact. +- An integration test: resolve one Short_Link 50 times through the Redirect API, + wait for the queue to drain, and assert the stored count is 50. + +## Risks + +This section names what could make the design fail and what is done about each: +the risk, its likelihood or impact, and the mitigation or the signal that will show it +happening. A risk with no mitigation says so plainly. + +- The queue backs up under a traffic spike and counts lag by minutes. Mitigation: alert + on queue depth over 10,000 and scale workers on depth. +- The Redirect API drops Visits when the queue is unavailable, so counts fall short. + Mitigation: the parent's Redirect API reports dropped visits; there is no replay, + which the parent's drop-and-log decision accepts. +- The processed-`eventId` store grows with traffic. Mitigation: 24-hour expiry; size it + before launch from the parent's 2,000,000 redirects a day. + +## Tasks + +This closing section breaks the component into tasks, each small enough for one +`/freethinking:start-task` run, roughly a dozen or fewer for one low level design. +Each entry is a short name, a line on what it covers, and the section of this document +it builds, so a reader can check that every section describing something to build +(Interfaces, Data, Behaviour and Testing) is built by some task and every task builds +something designed here.

The strategy it sets out is the year ahead for a +deliberately simple product, the Link Shortener that turns long URLs into short, +shareable links and counts how often each is visited, so the structure stays visible. +The high level design and low level design templates continue the same example one and +two levels down. + +A strategy is the highest level view of about a year of work, spanning one or more +projects. It says where the work is going and why, and breaks it into streams that each +get a high level design of their own; it never says how a stream is built.

The introduction answers +three questions in a short paragraph: what the work is, who it serves, and the horizon, +the dates the strategy covers and when it will be looked at again. + +The links platform takes the Link Shortener from an internal pilot to a product +customers rely on. It serves the marketing teams who share links today and the partners +who want to create links from their own systems. The horizon is January to December +2027, with a review at the end of each quarter. + +## Goals + +List the outcomes the year must deliver, each with what it is worth, so that when two +goals compete for the same people the reader can see which matters more. A goal is an +outcome someone outside the team can observe, not an activity; give each a measure the +team can check at the review. Three to five goals is usual; more than that is a sign +the strategy covers more than a year. + +1. **The shortener in general availability.** Every customer can create and resolve + Short_Links with redirects under 100 ms at the 99th percentile. Worth: the pilot's + marketing teams move off the third-party shortener, saving its licence by Q3. +2. **Click analytics.** Customers see visits per Short_Link by day, country and + referrer within five minutes of the visit. Worth: the reason most pilot users gave + for wanting the product, and the feature sales asks for first. +3. **A self-serve API.** Partners create and manage Short_Links through a documented API + with their own keys, without a ticket to the team. Worth: opens the partner channel + the business plan counts on for the second half of the year. + +## Current state + +Describe where things stand today, plainly and with numbers where they exist, so the +reader can see the gap each goal closes.

Visits are counted inline on each redirect, which holds at +today's load but adds a write to every request. There are no analytics beyond a total +per link, no public API and no per-customer keys; links are created through an internal +form.

Each is a sentence a high level design can be +checked against, with its reason when the reason is not obvious. Leave out what is true +of every project in the organisation; keep what this work must hold to. + +- The redirect path stays fast and simple: nothing slower than one key lookup sits + between a visitor and the destination, because a slow link reflects on the customer. +- Visit data is collected without cookies or personal data beyond country and referrer, + to stay within the privacy policy without a consent banner. +- Everything runs on the company's existing cloud account and its managed services; no + new vendor this year. +- The team is four engineers; any stream needing more than two at once has to be split. + +## Streams of work + +Break the year into streams, each a body of work one high level design can cover and a +small team can own. For each, say what it delivers, which goals it serves and roughly +when. Streams should cover every goal between them and overlap as little as possible; +where one depends on another, say so here, since that order sets the year's plan. + +1. **Shortener service.** Takes the pilot to general availability: redirect latency, + availability, per-customer links, and moving visit counting off the redirect path. + Serves goal 1. Q1 to Q2; the other two streams build on it. +2. **Click analytics.** Collects visits as events, aggregates them by day, country and + referrer, and shows them to customers. Serves goal 2. Q2 to Q3, starting once the + shortener emits visit events. +3. **Self-serve API.** A public API, per-partner keys, rate limits and documentation + over the shortener's create and manage operations. Serves goal 3. Q3 to Q4. + +## Risks + +Name what could stop the strategy delivering, each with how likely and how bad it is +and what the team will do about it. A risk is specific enough that someone could notice +it happening; "things take longer than planned" is not one, "the analytics store cannot +keep up with peak traffic" is. + +- **Analytics volume outgrows the store.** Visits could reach tens of millions a day if + a large partner joins. Likely in Q4, costly if it happens. The analytics design sizes + for ten times the pilot's load and names the next store before it is needed. +- **The API stream starts late.** It depends on the shortener stream finishing on time. + Moderate likelihood. The API design is written in Q2 so its build can start the day + the shortener ships. +- **Abuse through public links.** Open link creation invites phishing. Likely once the + API opens. Destination checks against a block list are part of the API stream. + +## Out of scope + +Say what the year will not do, especially what a reader might expect it to, so nobody +plans on it. Each entry is a sentence with the reason or the place it belongs. + +- Custom domains for Short_Links: asked for by two customers, deferred to 2028. +- QR codes: a front-end feature for the marketing site, not this platform. +- Moving off the current cloud account: ruled out by the constraints above. + +## High level designs + +Close with the high level designs this strategy expects, one Candidate per stream of +work, none written yet. Each is a kebab-case name, which becomes the design's folder +under `.freethinking/designs/links-platform-2027/`, and a line on what it covers. The +`hld` skill takes one of these names and this document's path to write the design. + +- `shortener-service`: the Short_Link service to general availability, from the + redirect path and its latency to asynchronous visit counting and per-customer links. +- `click-analytics`: visit events, their aggregation by day, country and referrer, and + the customer-facing reports. +- `self-serve-api`: the public API, partner keys, rate limits, abuse checks and the + documentation partners work from.
