Type: L2 Coordinator Category: 3XX Planning

Multi-Agent Validator

Evaluation-platform coordinator for:

• mode=story
• mode=plan_review
• mode=context

This skill uses the evaluation platform for:

• mandatory official-doc, MCP Ref, Context7, and current-web research
• parallel read-only evidence lanes
• sequential documentation, repair, merge, refinement, and approval
• runtime-backed worker plans, worker summaries, agent sync, and cleanup verification

Inputs

Mode detection:

• plan or plan {file} -> mode=plan_review
• context -> mode=context
• otherwise -> mode=story

Mandatory Read

MANDATORY READ: Load shared/references/environment_state_contract.md, shared/references/storage_mode_detection.md, shared/references/input_resolution_pattern.md MANDATORY READ: Load shared/references/evaluation_coordinator_runtime_contract.md, shared/references/evaluation_summary_contract.md, shared/references/evaluation_parallelism_policy.md, shared/references/evaluation_research_contract.md MANDATORY READ: Load shared/references/agent_review_workflow.md, shared/references/agent_delegation_pattern.md MANDATORY READ: Load references/phase2_research_audit.md, references/penalty_points.md

Worker Set

The coordinator uses these evaluation workers:

• ln-311-review-research-worker
• ln-312-review-findings-worker
• ln-313-review-docs-worker
• ln-314-review-repair-worker
• ln-315-review-merge-worker
• ln-316-review-refinement-worker

Worker Invocation (MANDATORY)

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

TodoWrite format (mandatory):

• Resolve target and build runtime manifest
• Load target artifacts and metadata
• Launch external agents and verify health
• Run research and findings workers in parallel
• Generate documentation updates
• Apply accepted low-risk repairs
• Sync agents and merge all evidence
• Run refinement (MANDATORY in ALL modes when Codex available — do NOT skip)
• Compute verdict and write review output
• Verify runtime cleanup and self-check

Parallelism Rules

Allowed overlap:

• external agents
• ln-311
• ln-312
• local repo inspection and evidence gathering

Sequential only:

• ln-313
• ln-314
• ln-315
• ln-316
• approval and status mutation

Workflow

Phase 0: Config

1. Resolve mode, identifier, and storage mode.
2. Resolve story, plan, or context target.
3. Build evaluation runtime manifest with:
   • expected_agents
   • required_research=true
   • exact phase_order
   • phase_policy
   • report path
   • extra_evidence_workers — optional list of additional read-only workers. Each entry: {"worker": "ln-511", "lane": "code_quality", "join_group": "evidence", "depends_on": []}. Default: empty list. Auto-selection in mode=story: label security → add ln-621, label performance → add ln-653.
4. Start runtime:

node shared/scripts/evaluation-runtime/cli.mjs start \
  --skill ln-310 \
  --identifier {identifier} \
  --manifest-file .hex-skills/evaluation/{identifier}_manifest.json

5. Checkpoint Phase 0.

Phase 1: Discovery

1. Materialize the exact target artifact.
2. Load only the metadata needed for the current mode.
3. In mode=story, resolve Story and child tasks.
4. In mode=plan_review, resolve the plan file.
5. In mode=context, materialize discussion context when needed.
6. Checkpoint Phase 1 with resolved refs.

Phase 2: Agent Launch

1. Run agent health check.
2. Exclude disabled agents from .hex-skills/environment_state.json.
3. If no agents are available:
   • record agents_skipped_reason
   • checkpoint Phase 2
   • continue
4. Otherwise:
   • build per-agent prompts
   • launch each available agent
   • register each launched agent:

node shared/scripts/evaluation-runtime/cli.mjs register-agent \
  --skill ln-310 \
  --identifier {identifier} \
  --agent {name} \
  --prompt-file {promptPath} \
  --result-file {resultPath} \
  --metadata-file {metadataPath}

5. Checkpoint Phase 2 with health_check_done, agents_available, agents_required, and optional agents_skipped_reason.

Phase 3: Evidence Lanes

This phase is the mandatory parallel evidence barrier.

1. Build worker_plan with:
   • ln-311 lane research (mandatory)
   • ln-312 lane findings (mandatory)
   • optional audit lanes from manifest extra_evidence_workers
2. Runtime gate: For each extra worker, verify it emits an evaluation-worker summary with worker, status, operation, and warnings. Skip unknown or non-evaluation summary formats with a warning.
3. Launch all planned workers in parallel.
4. While those workers run, continue local repo inspection and collect additional evidence.
5. Sync agents opportunistically, but do not block on them until merge.
6. Record each worker summary with:

node shared/scripts/evaluation-runtime/cli.mjs record-worker-result \
  --skill ln-310 \
  --identifier {identifier} \
  --payload-file {childSummaryArtifactPath}

Research is mandatory in every mode:

• official documentation or standards
• MCP Ref
• Context7 when a library or framework is involved
• current web best-practice research

For mode=story, findings must still produce penalty-point evidence and coverage analysis.

Phase 4: Docs

1. In mode=story, run ln-313-review-docs-worker when documentation changes are required.
2. In mode=plan_review and mode=context, skip only when there is no documentation delta to create.
3. Record the worker summary or explicit skip rationale.

Phase 5: Repair

1. Apply accepted low-risk repairs through ln-314-review-repair-worker.
2. Do not merge repair logic into research or findings lanes.
3. Record summary and any cleanup evidence.

Phase 6: Merge

Preconditions:

• all planned evidence workers resolved
• all required agents resolved or explicitly skipped

Steps:

1. Sync agents once at the merge barrier:

node shared/scripts/evaluation-runtime/cli.mjs sync-agent --skill ln-310 --identifier {identifier}

2. Run ln-315-review-merge-worker.
3. Deduplicate:
   • local findings
   • worker findings
   • agent findings
   • prior review history
4. Reject unsupported claims.
5. Apply only verified accepted changes.
6. Checkpoint Phase 6 with aggregation_summary.

Phase 7: Refinement

NEVER SKIP THIS PHASE. Phase 7 applies to ALL modes: story, plan_review, context. The ONLY valid skip reason is Codex unavailable in health check. Mode is NOT a skip reason. Complexity is NOT a skip reason. Time is NOT a skip reason. If you are about to checkpoint Phase 7 without running ln-316 — STOP. You are making an error.

Phase 7 is MANDATORY when Codex is available. The coordinator MUST NOT checkpoint Phase 7 without a recorded review-refinement worker summary from ln-316. The runtime advance command will reject the transition if Codex was available in health check but no refinement summary exists.

Run ln-316-review-refinement-worker. Refinement uses a 2-stage state machine:

• Stage 1: 3 parallel Codex sessions (dry_run_executor, new_dev_tester, adversarial_reviewer)
• Stage 2: 1 sequential Codex session (final_sweep) after merging Stage 1 results

Rules:

• all 4 perspectives are mandatory
• Stage 1 runs in parallel, Stage 2 runs after Stage 1 merge
• each perspective = independent Codex process via agent_runner.mjs (NOT Claude sub-agents)
• every launched process requires cleanup evidence
• refinement trace is mandatory
• wait for Codex results via Claude Monitor tool with 2-minute cycles

Phase 8: Approval

Story mode:

1. Compute final gate from post-merge and post-refinement state.
2. Final Assessment Model:

3. Gate rules:
   • GO = penalty_after=0 AND no FLAGGED items AND ac_coverage=100%
   • NO_GO = otherwise
   • Coverage: 80-99% = +3 penalty and forced NO_GO
   • Coverage: <80% = +5 penalty and forced NO_GO
4. On GO: mutate Story status to Todo; update kanban_board.md to APPROVED.
5. Retry status transition once; if failure → NO_GO.
6. Write user-facing review output with per-criterion penalty before/after breakdown.

Plan/context mode:

• write final review output without workflow mutation

Write coordinator summary:

node shared/scripts/evaluation-runtime/cli.mjs record-summary \
  --skill ln-310 \
  --identifier {identifier} \
  --payload '{...evaluation-coordinator summary...}'

Phase 9: Self-Check

Required checks:

• runtime started
• discovery checkpoint exists
• agent health recorded
• mandatory research completed
• all required worker summaries recorded
• all required agents resolved before merge
• merge summary exists
• refinement trace exists when Codex was available
• background cleanup evidence recorded
• cleanup verified
• coordinator summary recorded
• final result recorded

Then:

node shared/scripts/evaluation-runtime/cli.mjs complete --skill ln-310 --identifier {identifier}
