Description

This is the third of three PRs splitting #221. It is stacked on #238 (secret redaction) because the recommendation analyst calls redactSecrets, so review #238 first. It carries the run-diagnostics and reporter changes.

Recommendation analyst

  • Runs on every agent job now, including the no-tools control run, because correct work that fails a check on that run is the cleanest evidence of a grader defect (run-helper.ts, generator.ts).
  • Routes each finding to the surface that owns the fix. The category set widens from grader/skill/mcp/efficiency to also include eval, cli, and docs, and cli/docs/mcp are offered only when the run actually reached that surface (generator.ts, types.ts).
  • Adds a per-finding diagnosis (what_happened, what_should_have_happened, evidence, root_cause) and sends the full run trace plus a recursive reference-file pool, so the analyst can attribute a failure instead of guessing (generator.ts, collect-skill-content.ts).
  • A failed analysis now comes back carrying its error instead of undefined, so a proxy 500 no longer renders as a clean run.

Reporter

  • Renders each run's recommendations inline in its own report panel, with a severity summary on the tab and a distinct "analysis did not run" state so a failed analysis is not mistaken for a clean run (report.html.j2, report.css).

Docs

  • Updates docs/ADDING_EVALS.md and docs/ARCHITECTURE.md for the above.

Behavior note: because recommendations now run for every agent job, a full matrix makes one extra analysis call per no-tools agent run that was previously skipped, so expect a modest increase in judge-model calls.

References

Split out from #221. Stacked on #238.

Summary by CodeRabbit

  • New Features

    • Recommendations are now generated for all agent runs, including control runs without tools.
    • Findings include categories, severity, root causes, evidence, traces, and actionable guidance.
    • Recommendation analysis now reports clear failure states instead of appearing empty.
    • Skill references are collected recursively for more complete analysis.
    • Secrets are redacted from displayed analysis details.
  • Improvements

    • Reports now show recommendation counts, badges, evidence, and detailed diagnostics.
    • Incomplete runs retain available graders, metrics, traces, and recommendations.
    • Added guidance for writing outcome-focused evaluations.

New redactSecrets / REDACTION_MARKER masks credential values in the run
trace, MCP arguments, and error text before anything is sent to an LLM
judge or the recommendation analyst. The value is replaced rather than
the line dropped, so a security grader still sees that a secret occupied
that position. The judge command trace is scrubbed through the same
path.
Run recommendations now analyse every agent job, including the no-tools
control run, because correct work that fails a check there is the
cleanest evidence of a grader defect. Findings are routed to the surface
that owns the fix (skill, grader, eval, cli, docs, mcp, efficiency),
each carries a diagnosis (what_happened, what_should_have_happened,
evidence, root_cause), and the analyst is given the full run trace plus
a recursive reference-file pool. A failed analysis now carries its error
instead of undefined. The reporter renders each run's recommendations in
its own panel with a severity summary and a distinct did-not-run state.
The cross-run aggregation was removed as dead code; the report renders
recommendations per run only. Remove the paragraph describing the
deleted function.

📝 Walkthrough

Walkthrough

Recommendation analysis now runs for eligible agent jobs, including no-tool runs. It collects structured skill context and traces, redacts secrets, returns findings or errors, and renders expanded recommendations and incomplete-run details in reports.

Changes

Recommendation analysis and reporting

Layer / File(s) Summary
Recommendation contracts and skill context
packages/evals-core/src/recommendations/types.ts, packages/evals/src/recommendations/collect-skill-content.ts, packages/evals/src/recommendations/index.ts
Recommendation types support eval, cli, and docs categories, diagnostic fields, and analysis errors. Skill files are collected recursively in deterministic order.
Trace-aware recommendation analysis
packages/evals/src/recommendations/generator.ts, packages/evals/tests/recommendations.test.ts
The generator builds scoped prompts from traces and skill files, redacts secrets, supports expanded diagnosis output, handles truncation, extracts JSON from multiple response formats, and returns structured failures.
All-agent-run recommendation wiring
packages/evals/src/recommendations/run-helper.ts, packages/evals/src/cli/run.ts, packages/evals/src/cli/sandbox-runner.ts, docs/ARCHITECTURE.md
Recommendation generation includes no-tool agent runs, collects skill files only when enabled, preserves failures, and runs before workspace cleanup.
Recommendation and incomplete-run reports
packages/evals-reporter/src/templates/report.html.j2, packages/evals-reporter/src/templates/report.css, packages/evals-reporter/tests/*
Reports render finding totals, metadata, evidence, suggestions, and failed analyses. Content-bearing incomplete runs retain diagnostic details and show status messaging.
Evaluation prompt guidance and Docker test cleanup
docs/ADDING_EVALS.md, packages/evals/tests/docker.test.ts
Evaluation guidance favors outcome-based checks. Docker tests remove symlinks without following their targets.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to bb5c0

The PR expands recommendation analysis and reporting, but skill-file collection failures may still turn into job errors and the diagnosis schema may suppress valid eval or CLI root causes, leading to incomplete or misleading findings. These are bounded risks that require explicit owner awareness or follow-up before relying on the new diagnostics broadly.

Inline comments:
In `@docs/ADDING_EVALS.md`:
- Line 125: Update the example description around matches() to avoid claiming it
verifies file creation. Describe it as checking workspace-file contents, or
replace it with a route-independent assertion that confirms
smoke-b2b-manifest.json exists at the intended workspace path.

In `@docs/ARCHITECTURE.md`:
- Around line 333-362: Update both Mermaid diagrams in ARCHITECTURE.md to
reflect that generateRunRecommendations runs for every agent job, receives the
complete run context and reference pool, redacts secrets, and returns structured
findings or an explicit analysis error. Show recommendations attached to the
producing run and distinguish actual tool-surface scope from unavailable
surfaces, keeping both diagrams consistent with the surrounding prose.

In `@packages/evals-reporter/src/templates/report.css`:
- Line 511: Replace the deprecated word-break: break-word declaration with
overflow-wrap: anywhere in the .rec-where, .rec-evidence, and .rec-failed-reason
CSS rules.

In `@packages/evals/src/recommendations/collect-skill-content.ts`:
- Around line 21-30: Update walkMarkdown to catch failures from readdirSync and
skip unreadable or removed directories, allowing traversal to continue and
preserve the existing behavior for readable directories and markdown files.

In `@packages/evals/src/recommendations/generator.ts`:
- Around line 337-342: Update the JSON schema construction near the root_cause
definition to derive its enum from the same conditions used to compute
categories, including eval and cli where applicable and excluding skill when
skillCause indicates it is unavailable. Keep the enum aligned with
VALID_ROOT_CAUSES and the prompt’s available cause descriptions.

In `@packages/evals/src/recommendations/run-helper.ts`:
- Around line 39-45: The skills file collection in generateRecommendations
currently occurs outside the error-handling path, allowing collectSkillFiles
failures to escape as job errors. Move or wrap the collectSkillFiles call and
related skill setup in the existing try/catch so read failures return a
Recommendations value with its error field populated, and add a regression test
covering a SKILL.md read failure.

- Derive the schema's root_cause enum from the same conditions as categories,
  so eval and cli are reachable and skill is dropped on control runs.
- Skip an unreadable references directory or SKILL.md while collecting skill
  content, keeping generateRunRecommendations from throwing a job error.
- Replace deprecated word-break: break-word with overflow-wrap: anywhere.
- Clarify that matches() checks file contents, not path existence.

The opt "skills or MCP active" block implied the no-tools control run is not
analysed, but generateRunRecommendations runs on every agent job. Drop the
conditional so the diagram matches the prose.
