From 7eb923f0d2d1eaf82d16725fa517c6438dc8c766 Mon Sep 17 00:00:00 2001 From: jack Date: Wed, 15 Jul 2026 02:13:27 +0800 Subject: [PATCH 01/12] feat(review): V1 LLM approval reviewer (guardian) Add an opt-in LLM auto-reviewer that adjudicates tool calls which would otherwise interrupt the user with an approval prompt. It runs a small, dedicated model against a risk policy and returns allow / deny / escalate. - internal/review: reviewer engine (single-shot Generate + strict-JSON verdict + parse retry), risk policy adapted from codex guardian, JSONL audit log, BuildFromConfig. - runner: reviewer seam in ApprovalState (runs after decide()->prompt, before asking the user), denial circuit breaker, transcript provider. - agent: ReviewDeniedError so the model receives the reviewer's rationale with anti-workaround guidance, distinct from user rejection. - config: approval_review block (opt-in; reuses small_model, falls back to main model). Off by default => behavior unchanged. - Wired into ACP; teammates covered via the shared gatedApproval path. Fail-open: any model error/timeout/unparseable output escalates to the user. Verified end-to-end over ACP (allow skips prompt, small_model routing, audit log, fail-open escalation) plus unit tests.

Reviews serialize on the trunk; a failed review leaves the trunk unchanged so the cached prefix stays clean; the trunk is trimmed in whole (action,verdict) pairs. Fully separate from the main conversation (own model, own message list), so it cannot pollute the main cache. Verified over ACP: - cache hit: reviews 2..5 served ~89% of prompt from cache (zhipuai), latency dropped accordingly; review 1 writes the cache. - non-pollution: main model cache hit rate unchanged with reviewer on vs off (91.7% vs 95.0%, within run variance) using a separate model bucket for the reviewer.

39cd41e8de005aa364360faf638b88921c9fb966 Mon Sep 17 00:00:00 2001 From: jack Date: Wed, 15 Jul 2026 02:42:55 +0800 Subject: [PATCH 05/12] feat(review): wire reviewer into TUI + web; add eval + test report MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - TUI (interactive.go) and web (engine.go/chat.go/web.go) now install the reviewer via the same seam as ACP: SetReviewer + a transcript provider (reads history under the surface's existing lock discipline) + per-turn OnTurnStart breaker reset. Disabled config => unchanged behavior. - internal/review/eval_test.go: live-model judgment eval (skipped unless JCODE_REVIEW_EVAL=1) — 22 benign/dangerous/injection/authorization scenarios, graded (safety miss = allow of a dangerous unauthorized call). - internal-doc/approval-review-test-report.md: test report. - Remove now-dead requestUserApproval helper (gatedApproval supersedes it).

Policy now says: deny = block outright, escalate = ask the human. - Engine.Review recovers panics -> Escalate (fail-open), so a reviewer bug can't fail-closed-block a call via the middleware's generic panic handler. - Document known limitations surfaced by the review: V2 investigate assumes local fs (wrong on remote/SSH), reviewer spend hits the global token counter, transcript lacks in-turn tool output, breaker is session-global.

Review findings: 1. SSRF/metadata hardening was prompt-only — the same defense class the eval proved can be talked out of. Add internal/review/ssrf.go: a deterministic pre-filter that runs BEFORE the model. Metadata address (incl. decimal/hex/ octal obfuscations) + credential path -> deny; bare address mention -> escalate (a deny cannot be overridden by the user, an escalate can). Covered by normal-CI unit tests, including a wiring test proving it decides without a model. Policy prose stays as defense-in-depth. 2. V2 investigate could adopt a reflected/injected JSON blob as its verdict (newest->oldest scan). Now only the reviewer's FINAL message counts; anything else escalates. Injection regression test added. 3. V3 trunk re-embedded the full transcript every review and trimmed by count only, so it could grow past the context window — making V3 costlier than V1. Now: transcript is re-sent only when it actually changes (fingerprinted; the frontends only extend history between turns), and trimTrunk enforces a byte budget as well as a count. A trim forces the next review to re-send evidence. 4. background=true could be silently reviewer-approved, weakening a previously human-only rule. Corrected the stale comment (the invariant is "the flag cannot buy a free pass", not "a human sees every background command") and made background_execution an explicit risk signal in the prompt + policy. CodeRabbit: - Extract review.MsgsFromHistory; ACP/TUI/web now share one transcript helper. - Redact credential-shaped values (auth headers, --password/--token, secret env assignments, gh_/xox/AKIA/sk- prefixes, private keys) before writing the append-only audit log.

The reviewer loses its approval_review.enabled switch; Auto mode is now the switch. ApprovalState builds the reviewer lazily on entering Auto and drops it on leaving, so BuildFromConfig no longer returns nil and the three frontends stop each deciding whether to wire it. Auto keeps the approval axis on Manual — the reviewer is an extra gate, not a bypass, and can still prompt when it escalates. Expose the tuning knobs via /api/approval-review-config + a settings section: the model picker reuses the small_model role picker's grouped enabled-model list, and timeout/audit-path keep "empty = built-in default" while showing the server's resolved defaults as placeholders. '' and the 'small' alias resolve identically in resolveModelRef, so they share one option rather than offering two spellings of the same thing. Fixes found reviewing the above (each covered by a regression test that was confirmed to fail against the pre-fix code): 1. TUI "Approve all" moved only the approval axis, so the mode pill kept naming the old mode while the backend had already gone to Full access, and the next Shift+Tab cycled from that stale value. It now promotes the unified mode too — except during Plan, where the backend keeps the read-only tool set and the tool axis still names the mode. 2. An approved plan moving to execution recorded and displayed Plan while already holding the full tool set, so the session claimed read-only while writable. Leaving the plan tool axis now normalizes to Approval, matching how resume treats a saved Plan. 3. The settings form POSTed an empty config over the stored one when its initial GET failed (the error was swallowed, cfg stayed {}). A failed load now renders an error + retry with no form to submit. 4. The web settings handler swapped Config.ApprovalReview in place while a task goroutine read it to build its reviewer, holding no lock in common — a real data race, confirmed under -race. Both sides now go through synchronized accessors returning a snapshot. The lock is package-level because Config is copied by value elsewhere and an embedded mutex would trip go vet's copylocks.
