Quality Coordinator

Evaluation-platform coordinator for story quality review.

Mandatory Read

MANDATORY READ: Load shared/references/evaluation_coordinator_runtime_contract.md, shared/references/evaluation_summary_contract.md, shared/references/evaluation_research_contract.md, shared/references/loop_health_contract.md MANDATORY READ: Load shared/references/agent_review_workflow.md, shared/references/agent_delegation_pattern.md MANDATORY READ: Load references/criteria_validation.md, references/gate_levels.md

Purpose

• invoke ln-511-code-quality-checker
• invoke ln-512-tech-debt-cleaner
• invoke ln-513-regression-checker
• invoke ln-514-test-log-analyzer
• run inline agent review in parallel with read-only evidence gathering
• keep merge, refinement, and verdict sequential
• return normalized quality results

Inputs

Primary input:

• storyId
• --previous-cycle-focus (optional, from ln-500): comma-separated blocking categories from prior FAIL cycle

Status filter:

• To Review

Critical Rule

Fast-track paths that skip research are not allowed.

Every quality run must include:

1. official documentation or standards
2. MCP Ref
3. Context7 when a framework or library is involved
4. current web best-practice research

Runtime Contract

Runtime family:

• evaluation-runtime

Identifier:

• quality-{storyId}

Phase order:

1. PHASE_0_CONFIG
2. PHASE_1_DISCOVERY
3. PHASE_2_READ_ONLY_EVIDENCE
4. PHASE_3_CLEANUP
5. PHASE_4_AGENT_BARRIER
6. PHASE_5_MERGE
7. PHASE_7_REFINEMENT
8. PHASE_8_VERDICT
9. PHASE_9_SELF_CHECK

Worker Invocation (MANDATORY)

Use the Skill tool for delegated workers. Do not inline worker logic inside the coordinator.

TodoWrite format (mandatory):

• Resolve Story and build runtime manifest
• Load Story metadata and detect changed files
• Run quality checkers and research in parallel
• Apply safe tech-debt cleanup
• Sync agents and wait for all evidence
• Merge and deduplicate all findings
• Run bounded refinement loop
• Compute quality verdict and score
• Verify runtime cleanup and self-check

Representative invocations:

Skill(skill: "ln-511-code-quality-checker", args: "{storyId}")
Skill(skill: "ln-512-tech-debt-cleaner", args: "{storyId}")
Skill(skill: "ln-513-regression-checker", args: "{storyId}")
Skill(skill: "ln-514-test-log-analyzer", args: "{storyId}")

Workflow

Phase 0: Config

1. Resolve storyId.
2. Build evaluation runtime manifest with required_research=true.
3. Start evaluation-runtime.

Phase 1: Discovery

1. Load Story metadata and completed implementation task scope.
2. Detect changed files and project stack.
3. Index semantic graph when available.

Phase 2: Read-Only Evidence

Parallel work allowed in this phase:

• inline research by the coordinator (per shared/references/evaluation_research_contract.md)
• ln-511-code-quality-checker
• ln-513-regression-checker
• ln-514-test-log-analyzer
• external agent launch

Rules:

• research is mandatory
• worker summaries are the only completion signal
• no merge or mutation occurs in this phase

When previous_cycle_focus is provided:

• Prioritize evidence collection for the listed blocking categories.
• ln-511 code quality checker should focus on the specified areas first.
• This does not exclude other evidence — it reorders priority.

Phase 3: Cleanup

1. Run ln-512-tech-debt-cleaner only after read-only evidence is collected.
2. Cleanup remains sequential because it mutates files.
3. Record the worker summary and any cleanup evidence.

Phase 4: Agent Barrier

1. Sync agents through evaluation-runtime.
2. Do not cross this barrier until all required agents are resolved or explicitly skipped.
3. Treat failure_class from agent results as transport evidence:
   • rate_limited, tool_missing, auth_missing, permission_denial, and asked_question are not quality FAIL findings by themselves.
   • timeout_productive can continue to merge/review only when output/log/session evidence exists.
   • repeated identical worker/agent failure without new artifacts pauses through loop health before another cycle.

Phase 5: Merge

Merge inputs:

• inline research evidence
• ln-511 summary
• ln-512 summary
• ln-513 summary
• ln-514 summary
• agent findings

Rules:

• deduplicate before scoring
• unsupported claims are rejected
• security and correctness issues remain high priority

Phase 6: Refinement

Refinement uses a 2-stage state machine per shared/agents/prompt_templates/iterative_refinement.md and shared/agents/prompt_templates/refinement_perspectives.md:

• Stage 1 (parallel): dry_run_executor, new_dev_tester, adversarial_reviewer
• Stage 2 (after merge): final_sweep

Rules:

• Stage 1 runs in parallel, Stage 2 after merge
• cleanup evidence required for spawned processes
• no research skipping

Phase 7: Verdict

Compute normalized quality verdict using:

• code quality
• cleanup result
• agent review
• criteria validation
• linter result
• regression result
• log analysis result

Final verdict values:

• PASS
• CONCERNS
• FAIL

Phase 8: Self-Check

Required checks:

• runtime started
• mandatory research completed
• all worker summaries recorded
• all required agents resolved before merge
• cleanup verified
• refinement trace recorded when applicable
• coordinator summary written

Summary Contract

Write summary_kind=evaluation-coordinator.

Recommended payload:

• status
• final_result
• report_path
• worker_count
• agent_count
• issues_total
• severity_counts
• warnings
• cleanup_verified
• research_completed

Definition of Done

• Evaluation runtime started
• Mandatory research completed
• Read-only evidence workers completed
• Cleanup worker completed or justified
• Agent barrier resolved
• Merge completed
• Refinement executed or explicitly justified
• Final verdict calculated
• evaluation-coordinator summary written
• Runtime completed

Meta-Analysis

MANDATORY READ: Load shared/references/meta_analysis_protocol.md

After the coordinator run, analyze the session per protocol section 7 and include the protocol-formatted output with the final quality verdict.
