Agent Reviewer (Code)

Runs parallel external agent reviews on code implementation, critically verifies suggestions, returns filtered improvements.

Purpose & Scope

• Worker in ln-510 quality coordinator pipeline (invoked by ln-510 Phase 4)
• Run codex-review + gemini-review as background tasks in parallel
• Process results as they arrive (first-finished agent processed immediately)
• Critically verify each suggestion; debate with agent if Claude disagrees
• Return filtered, deduplicated, verified suggestions with confidence scoring
• Health check + prompt execution in single invocation

When to Use

• Invoked by ln-510-quality-coordinator Phase 4 (Agent Review)
• All implementation tasks in Story status = Done
• Code quality (ln-511) and tech debt cleanup (ln-512) already completed

Parameters

Parameter	Value
review_type	codereview
skill_group	513
prompt_template	shared/agents/prompt_templates/code_review.md
verdict_acceptable	CODE_ACCEPTABLE

Inputs (from parent skill)

• storyId: Linear Story identifier (e.g., "PROJ-123")

Workflow

MANDATORY READ: Load shared/references/agent_review_workflow.md for Health Check, Ensure .agent-review/, Load Review Memory, Run Agents, Critical Verification + Debate, Aggregate + Return, Save Review Summary, Fallback Rules, Critical Rules, and Definition of Done. Load shared/references/agent_delegation_pattern.md for Reference Passing Pattern, Review Persistence Pattern, Agent Timeout Policy, and Debate Protocol.

Unique Steps (before shared workflow)

1. Health check: per shared workflow, filter by skill_group = 513.

2. Get references: Call Linear MCP get_issue(storyId) -> extract URL + identifier. Call list_issues(filter: {parent: {id: storyId}, status: "Done"}) -> extract Done implementation Task URLs/identifiers (exclude label "tests").

   • If project stores tasks locally (e.g., docs/tasks/) -> use local file paths instead of Linear URLs.

3. Ensure .agent-review/: per shared workflow.

4. Build prompt: Read template shared/agents/prompt_templates/code_review.md.

   • Replace {story_ref} with - Linear: {url} or - File: {path}
   • Replace {task_refs} with bullet list: - {identifier}: {url_or_path} per task
   • Save to .agent-review/{identifier}_codereview_prompt.md (single shared file -- both agents read the same prompt)

Shared Workflow Steps

5-8) Load Review Memory, Run agents, Critical Verification + Debate, Aggregate + Return: per shared workflow.

• {review_type} = "Code Implementation" (for challenge template)

9. Save Review Summary: per shared workflow "Step: Save Review Summary".

Output Format

verdict: CODE_ACCEPTABLE | SUGGESTIONS | SKIPPED
suggestions:
  - area: "security | performance | architecture | correctness | best_practices"
    issue: "What is wrong"
    suggestion: "Specific fix"
    confidence: 95
    impact_percent: 15
    source: "codex-review"
    resolution: "accepted | accepted_after_debate | accepted_after_followup | rejected"

Agent stats and debate log per shared workflow output schema.

Fallback Rules

Per shared workflow, plus:

Condition	Action
Parent skill (ln-510)	Falls back to Self-Review (native Claude)

Verdict Escalation

• Findings with area=security or area=correctness -> parent skill can escalate PASS -> CONCERNS
• This skill returns raw verified suggestions; escalation decision is made by ln-510

Critical Rules (additional)

• MANDATORY INVOCATION: Parent skills MUST invoke this skill. Returns SKIPPED gracefully if agents unavailable. Parent must NOT pre-check and skip.
