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

| Input | Required | Source | Description | |-------|----------|--------|-------------| | storyId | Yes | args, git branch, kanban, user | Story to process |

Resolution: Story Resolution Chain. Status filter: In Progress, To Review

Workflow

MANDATORY READ: Load shared/references/input_resolution_pattern.md, shared/references/tools_config_guide.md, shared/references/storage_mode_detection.md, shared/references/agent_review_workflow.md, and shared/references/agent_delegation_pattern.md.

Phase 0: Resolve Inputs & Tools Config

1. Resolve storyId (per input_resolution_pattern.md):

   • IF args provided → use args
   • ELSE IF git branch matches feature/{id}-* → extract id
   • ELSE IF kanban has exactly 1 Story in [In Progress, To Review] → suggest
   • ELSE → AskUserQuestion: show Stories from kanban filtered by [In Progress, To Review]

2. Extract: task_provider from docs/tools_config.md (per tools_config_guide.md).

Unique Steps (before shared workflow)

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

2. Get references:

   • IF task_provider = linear: get_issue(storyId) → extract URL + identifier. list_issues(filter: {parent: {id: storyId}, status: "Done"}) → extract Done implementation Task URLs/identifiers (exclude label "tests").
   • IF task_provider = file: Read story.md → extract path. Glob("docs/tasks/epics/*/stories/*/tasks/*.md") → filter Done tasks (check **Status:** Done), exclude label "tests".

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.
