From 0bb4f9ecb0f9e83ea8f9223267ec29c7733cd8f4 Mon Sep 17 00:00:00 2001 From: Peter Ulsteen Date: Tue, 11 Aug 2026 16:07:39 -0500 Subject: [PATCH] fix(code-review): load a domain critic's own agent definition into its spawn prompt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A domain critic declared in a project's critic-gates.json spawns as the generic code-review:code-review-worker and receives only its name as a quoted CRITIC_DOMAIN string, so `.claude/agents/.md` — which may define the critic's whole method — was never loaded. The only context-loading line in that prompt was the unranked "Read the repository CLAUDE.md for project context", which zero of twelve workers across three real runs obeyed. derive-spawn-spec now resolves the agent file and puts its path on the domain critic descriptor as agent_definition_file; cmd_route does the same for the fast path's PASS 3 under route.domain_critic_definitions. The spawn-reviewers skill turns that path into a non-negotiable first step in the critic's prompt. Both keys are omitted when the file does not exist, so a critic without one keeps a byte-identical descriptor, routing payload, and prompt. --- CHANGELOG.md | 5 + .../code-review/.claude-plugin/plugin.json | 2 +- .../skills/spawn-reviewers/SKILL.md | 22 +++ .../tools/python/code_review_helpers.py | 72 ++++++++- .../tools/python/test_code_review_helpers.py | 150 ++++++++++++++++++ 5 files changed, 248 insertions(+), 3 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index df86e39..e981343 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -4,6 +4,11 @@ All notable changes to the claude-plugins project will be documented in this fil The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

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. `derive-spawn-spec` now resolves `.claude/agents/.md` and, when the file exists, puts its path on the domain critic descriptor as `agent_definition_file`; `cmd_route` does the same for the fast path's PASS 3 under `route.domain_critic_definitions` (both keys are omitted entirely when no such file exists). The `spawn-reviewers` skill turns that path into a non-negotiable first step in the critic's prompt — read the definition before the patches file, follow it in full, and say so in the output if the read fails. A critic with no agent file, which is the common case, produces a byte-identical descriptor, routing payload, and prompt to before. Filename convention only: a definition whose frontmatter `name` differs from its filename is not resolved, and symlinks and non-regular files are refused (the pipeline reviews untrusted checkouts). + ### platform v1.1.4 #### Fixed diff --git a/plugins/code-review/.claude-plugin/plugin.json b/plugins/code-review/.claude-plugin/plugin.json index 684332f..de55d5a 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": "3.7.0", + "version": "3.7.1", "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..901fd7c 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.
