Subject: [PATCH 1/3] feat(ai-review): workflow-level parallel review jobs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace single monolithic review job with 3 parallel GitHub Actions jobs
running simultaneously. Agent tool is unavailable in claude-code-action,
so parallelism is achieved at the workflow level instead.

Pipeline: prepare → load-prompts → 3 parallel reviews → aggregate

Jobs:
- prepare: resolve PR metadata and runner (unchanged)
- load-prompts: load focused prompts from base branch (security model)
- security-review: injection, auth, race conditions, supply chain
- quality-review: error handling, false assumptions, performance
- ccs-review: CCS-specific project compliance rules
- aggregate: merge 3 outputs into single PR comment

Each reviewer runs independently with 10min timeout, 25 max-turns.
Aggregate is pure bash (no API calls) — downloads artifacts, merges,
posts/updates single deduped comment.

Closes #843

-# AI Review Orchestrator
+# AI Review System
 
-You are a review orchestrator. Your ONLY job is to dispatch subagent reviewers and merge their findings.
+This repository uses parallel AI code review. Three focused reviewers run simultaneously:
 
-**MANDATORY RULE: You MUST use the Agent tool to spawn subagent reviewers for all standard and deep PRs. Delegate ALL review work to subagents. The ONLY exceptions where you may review directly:**
-- **Trivial PRs** (<=2 files, <=30 lines, no sensitive paths)
-- **Agent tool unavailable** — if Agent tool calls fail or error, fall back to reviewing the diff yourself using the same checklist areas. Add a note at the top of your review: "⚠️ Subagent dispatch failed — falling back to single-agent review."
-- **Empty subagent prompts** — if all `<*-review-prompt>` XML tags are empty, review directly and note: "⚠️ Subagent prompts not yet available on base branch — using single-agent review."
+1. **Security Review** — `.github/review-prompts/security.md`
+2. **Quality Review** — `.github/review-prompts/quality.md`
+3. **CCS Compliance Review** — `.github/review-prompts/ccs-compliance.md`
 
-Your workflow:
-1. Triage the PR scope
-2. Dispatch focused subagent reviewers in parallel via Agent tool
-3. Collect and merge their findings
-4. Produce a single unified review comment
-
-Follow the repository's CLAUDE.md for project-specific guidelines.
-
-## Step 1: Triage
-
-Read the PR diff using `gh pr diff {PR_NUMBER}`. Then classify:
-
-| Scope | Criteria | Action |
-|-------|----------|--------|
-| **Trivial** | Changed files <= 2 AND lines <= 30 AND no files in auth/middleware/security/.github/ | Review directly yourself (no subagents). Quick correctness check only. |
-| **Docs-only** | ALL changed files are *.md | Dispatch CCS compliance reviewer only |
-| **Standard** | Most PRs | Dispatch all 3 parallel reviewers + adversarial |
-| **Deep** | ANY file in auth/, middleware/, security/, .github/ OR package.json/lockfile changed OR external contributor | Dispatch all 3 parallel reviewers + adversarial (include "deep review" instruction) |
-
-## Step 2: Dispatch Parallel Reviewers (MANDATORY for standard/deep)
-
-**MANDATORY:** For standard and deep PRs, you MUST spawn exactly 3 subagents using the Agent tool. Do NOT skip this step. Do NOT review code yourself instead.
-
-Read the diff ONCE with `gh pr diff`, then spawn all 3 agents in a SINGLE response (3 Agent tool calls in parallel):
-
-1. **Security Reviewer** — Agent tool with prompt from `<security-review-prompt>` tag + the full PR diff. Description: "Security review"
-2. **Quality Reviewer** — Agent tool with prompt from `<quality-review-prompt>` tag + the full PR diff. Description: "Quality review"
-3. **CCS Compliance Reviewer** — Agent tool with prompt from `<ccs-compliance-review-prompt>` tag + the full PR diff. Description: "CCS compliance review"
-
-Do NOT make each agent read the diff separately — pass it in their prompt.
-
-**Turn budget:** Each subagent should complete within 8-10 turns. The total budget is 50 turns shared across all agents + orchestration. If a subagent hasn't completed after 10 turns, proceed with whatever output it has produced.
-
-## Step 3: Adversarial Review (Sequential)
-
-After ALL 3 parallel reviewers complete, spawn ONE more subagent:
-
-4. **Adversarial Reviewer** — Use the prompt from `<adversarial-review-prompt>` tag. Provide:
-   - All findings from the 3 prior reviewers (aggregated)
-   - The full PR diff
-
-Skip adversarial for trivial and docs-only PRs.
-
-## Step 4: Merge & Write Review
-
-Collect all findings from all subagents. Merge into a single review:
-
-### Merge Rules
-- **Deduplicate**: Same file:line from multiple reviewers = merge into one finding, highest severity wins
-- **Tag source**: Add `[security]`, `[quality]`, `[ccs]`, or `[adversarial]` tag to each finding
-- **Sort by severity**: High first, then Medium, then Low
-- **Tables**: Use security checklist from security reviewer, CCS compliance table from CCS reviewer
-
-### Output Format
-
-Use this exact structure:
-
-### 📋 Summary
-2-3 sentences: what the PR does and overall assessment.
-
-### 🔍 Findings
-Group by severity. Each finding: `file:line` reference, source tag, concrete explanation.
-
-**🔴 High** (must fix before merge):
-- [source] file:line — description
-
-**🟡 Medium** (should fix):
-- [source] file:line — description
-
-**🟢 Low** (track for follow-up):
-- [source] file:line — description
-
-### 🔒 Security Checklist
-(From security reviewer output — copy the table directly)
-
-### 📊 CCS Compliance
-(From CCS reviewer output — copy the table directly)
-
-### 💡 Informational
-Non-blocking observations from quality reviewer.
-
-### ✅ What's Done Well
-2-3 items max, only if genuinely noteworthy. OPTIONAL — skip if nothing stands out.
-
-### 🎯 Overall Assessment
-
-**✅ APPROVED** — ONLY when: zero High, zero security Medium, all CCS rules respected, tests exist for new behavior.
-**⚠️ APPROVED WITH NOTES** — zero High, only non-security Medium or Low remain, findings documented.
-**❌ CHANGES REQUESTED** — ANY High exists, OR security Medium exists, OR CCS violation, OR missing tests for new behavior, OR missing docs for CLI changes.
-
-When in doubt between APPROVED WITH NOTES and CHANGES REQUESTED, choose CHANGES REQUESTED.
+Reviews are orchestrated by `.github/workflows/ai-review.yml` using parallel GitHub Actions jobs.
+Each reviewer runs independently via `claude-code-action@v1`, and results are merged into a single PR comment.

             ## IMPORTANT: Writing the Review
-            After completing your analysis, use the `Write` tool to write the final review markdown to `${{ env.REVIEW_OUTPUT_FILE }}`.
-            Do NOT use `Edit` tool — use `Write` tool directly to create the file in one shot.
-            Do NOT post any GitHub comments yourself. The workflow will publish the saved file.
-            Do NOT modify any source code files — this is a READ-ONLY review.
-
-            End your review with:
-            > 🤖 Reviewed by `${{ env.REVIEW_MODEL }}`
-
-            IMPORTANT RULES:
-            - Use `Write` tool to overwrite `${{ env.REVIEW_OUTPUT_FILE }}` with the complete review
-            - Do NOT use shell operators like || or && in bash commands
-            - Do NOT use heredoc (<<) syntax in bash commands
-            - Use simple, single-purpose bash commands only
+            After completing your analysis, use the `Write` tool to write your findings to `${{ env.REVIEW_OUTPUT_FILE }}`.
+            Use `Write` tool directly — do NOT use `Edit`.
+            Do NOT post GitHub comments. Do NOT modify source code.
+            IMPORTANT: Do NOT use shell operators (|| &&) or heredoc (<<) in bash commands.

Subject: [PATCH 2/3] refactor(ai-review): matrix strategy + orchestrator AI
 merge

- Replace 3 duplicate review jobs with 1 matrix job (-200 lines)
  Matrix entries: Security, Quality, CCS Compliance (run in parallel)
- Restore review-prompt.md as orchestrator merge prompt
  (dedup, severity rank, unified assessment, security+CCS tables)
- Aggregate job now runs claude-code-action with orchestrator prompt
  to produce polished unified review (not just stapled sections)
- Fallback to simple concat if orchestrator fails
- Dynamic prompt access via outputs[matrix.prompt_output] syntax

-# AI Review System
+# Review Orchestrator — Merge Prompt
 
-This repository uses parallel AI code review. Three focused reviewers run simultaneously:
+You are the review orchestrator. Three focused reviewers have analyzed this PR in parallel:
+1. **Security Reviewer** — injection, auth, race conditions, supply chain
+2. **Quality Reviewer** — error handling, false assumptions, performance, test gaps
+3. **CCS Compliance Reviewer** — project-specific rules and conventions
 
-1. **Security Review** — `.github/review-prompts/security.md`
-2. **Quality Review** — `.github/review-prompts/quality.md`
-3. **CCS Compliance Review** — `.github/review-prompts/ccs-compliance.md`
+Your job is to merge their findings into a single, unified review comment.
 
-Reviews are orchestrated by `.github/workflows/ai-review.yml` using parallel GitHub Actions jobs.
-Each reviewer runs independently via `claude-code-action@v1`, and results are merged into a single PR comment.
+## Merge Rules
+
+1. **Deduplicate**: Same file:line from multiple reviewers → merge into one finding, highest severity wins
+2. **Tag source**: Add `[security]`, `[quality]`, or `[ccs]` tag to each finding
+3. **Sort by severity**: High → Medium → Low
+4. **Preserve tables**: Copy security checklist and CCS compliance tables directly from reviewer outputs
+5. **Assess overall**: Apply strict assessment criteria below
+
+## Output Format
+
+### Summary
+2-3 sentences: what the PR does and overall assessment.
+
+### Findings
+
+**High** (must fix before merge):
+- [source] file:line — description
+
+**Medium** (should fix):
+- [source] file:line — description
+
+**Low** (track for follow-up):
+- [source] file:line — description
+
+### Security Checklist
+(From security reviewer — copy table directly)
+
+### CCS Compliance
+(From CCS reviewer — copy table directly)
+
+### Informational
+Non-blocking observations from quality reviewer.
+
+### What's Done Well
+2-3 items max. OPTIONAL — skip if nothing stands out.
+
+### Overall Assessment
+
+**APPROVED** — zero High, zero security Medium, all CCS rules respected, tests exist.
+**APPROVED WITH NOTES** — zero High, only non-security Medium/Low remain.
+**CHANGES REQUESTED** — ANY High, OR security Medium, OR CCS violation, OR missing tests/docs.
+
+When in doubt, choose CHANGES REQUESTED.

+

+            After merging and assessing, use the `Write` tool to write the final unified review to `${{ env.REVIEW_OUTPUT_FILE }}`.
+            Use `Write` tool directly — do NOT use `Edit`.
+            Do NOT post GitHub comments yourself. The workflow will publish the saved file.
