Entries are listed newest-first; each plugin section is treated as released when merged to `main`. +### code-review v3.7.2 + +#### Fixed +- **A project-declared domain critic now loads its own agent definition.** Domain critics spawn as the generic `code-review:code-review-worker` and receive only their name as a quoted `CRITIC_DOMAIN` string, so a project that defines the critic's entire method in `.claude/agents/` got none of it — the only context-loading line in the domain critic prompt was the unranked "Read the repository CLAUDE.md for project context", which sits after the hard `FIRST…THEN…` block. Across three real `/code-review` runs in a consuming repo (`cr-51875`, `cr-95074`, `cr-97905`), zero of twelve spawned workers obeyed that line; the one critic that did read project doctrine got there by spontaneously grepping its own domain token, and self-describing critic names (`api-architect`, `auth-security-expert`) never self-grep at all. The critic still ran and still emitted plausible findings, with nothing in the output artifact recording that its definition was never loaded. + - **Identity is the frontmatter `name`, not the filename.** `cmd_route` resolves definitions through a name→path index built by the same walk that produces `available_reviewers.json`, so `soul.md` declaring `name: review-soul` is the definition of `review-soul` — the case a filename lookup missed while the roster advertised the name, reproducing the silent no-doctrine spawn this fix exists to remove. A file with absent or malformed frontmatter has no identity and resolves to nothing. Sharing the walk also gives the lookup the roster's existing refusals — symlinked and non-regular leaves, the per-file byte cap, the file-count and roster caps — and a symlinked `.claude` or `.claude/agents` directory now refuses the whole scan on both paths, which a leaf `lstat` never saw. + - **Definitions the diff under review touches are not loaded.** The tree being reviewed is a contributor's PR head, so a definition file the PR itself adds or edits is the contributor's own instructions to the reviewer judging them. Those are dropped, which leaves only files byte-identical to the base; the prompt line is deleted and the critic runs exactly as it did before definitions were loaded at all. The prompt read is also ordered *after* `shared_prompt.txt` rather than before it, so the untrusted-content policy is in context first, and the definition is explicitly ranked below the shared review constraints, FILE SCOPE rules, severity guidelines, and output contract — it cannot narrow them or direct the critic to withhold a finding. + - **Resolved once per run, against the validated review root.** The lookup used to default to the process cwd, so a local PR review — whose source lives in an isolated PR-head worktree — resolved against the operator's checkout instead. `cmd_route` now resolves from the same validated `scope.json` → `review_root` every other source read goes through, and writes `route.domain_critic_definitions`; spawn-spec derivation reads that map instead of re-walking the filesystem at a second stage with a second cwd. The map is keyed by every available definition rather than by the critics route selected, because `coverage_critic` can propose a name route never saw. The fast path's PASS 3 and the static fallback table (neither of which has a spawn-spec descriptor) both read the same map — the fallback substitution is now stated explicitly instead of falling through the descriptor rule and deleting the line. + - **`definition_loaded` is checked, not trusted.** The critic reports it alongside `findings` in its output file, and `stage_20b_verify_spawn` compares that against the descriptors that carried an `agent_definition_file`. A resolved-but-unloaded definition emits a `coverage:critic-definition-not-loaded` gap (HIGH, `required: false` → NEEDS_ATTENTION) naming the critics, so a critic that skipped its doctrine is a coverage gap rather than a set of plausible findings — otherwise the fix inherits, one level up, the unenforced-prose failure mode it was written to remove. + - A critic with no resolvable definition, which is the common case, produces a byte-identical descriptor and prompt to before. + ### code-review v3.7.1 #### Fixed diff --git a/plugins/code-review/.claude-plugin/plugin.json b/plugins/code-review/.claude-plugin/plugin.json index de55d5a..4bc5c51 100644 --- a/plugins/code-review/.claude-plugin/plugin.json +++ b/plugins/code-review/.claude-plugin/plugin.json @@ -1,7 +1,7 @@ { "name": "code-review", "description": "Code review plugin", - "version": "3.7.1", + "version": "3.7.2", "author": { "name": "ClosedLoop", "email": "support@closedloop.ai" diff --git a/plugins/code-review/skills/spawn-reviewers/SKILL.md b/plugins/code-review/skills/spawn-reviewers/SKILL.md index 65e3a2e..f635fae 100644 --- a/plugins/code-review/skills/spawn-reviewers/SKILL.md +++ b/plugins/code-review/skills/spawn-reviewers/SKILL.md @@ -26,6 +26,7 @@ This stage runs when the walker reaches `stage_20`. - When `source == "core"`, branch on the `reviewer` field to select the suffix: `bug_hunter_a` → BHA, `bug_hunter_b` → BHB, `unified_auditor` → Auditor, `impact` → Impact Analyzer, `design_critic` → Design Critic.
