Type: L2 Coordinator Category: 8XX Optimization

Optimization Plan Validator

Coordinator for validating optimization plans before execution.

Mandatory Read

MANDATORY READ: Load shared/references/evaluation_coordinator_runtime_contract.md, shared/references/evaluation_summary_contract.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/optimization_review_focus.md

Purpose

• verify feasibility of optimization hypotheses
• require source-backed research before plan approval
• use parallel external agents plus local feasibility analysis
• keep merge and refinement sequential

Inputs

Primary input:

• .hex-skills/optimization/{slug}/context.md

Required context sections:

• performance map
• hypotheses
• suspicion stack
• test command

Runtime Contract

Runtime family:

• evaluation-runtime

Identifier:

• optimization-{slug}

Phase order:

1. PHASE_0_CONFIG
2. PHASE_1_LOAD_CONTEXT
3. PHASE_2_AGENT_LAUNCH
4. PHASE_3_RESEARCH_AND_FEASIBILITY
5. PHASE_4_MERGE
6. PHASE_5_REFINEMENT
7. PHASE_6_VERDICT
8. PHASE_7_SELF_CHECK

Worker Invocation (MANDATORY)

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

TodoWrite format (mandatory):

• Config
• Load context
• Agent launch
• Research and feasibility
• Merge
• Refinement
• Verdict
• Self-check

Representative invocations:

Skill(skill: "ln-311-review-research-worker", args: "{slug} optimization research")
Skill(skill: "ln-316-review-refinement-worker", args: "{slug} optimization refinement")

Workflow

Phase 0: Config

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

Phase 1: Load Context

1. Load .hex-skills/optimization/{slug}/context.md.
2. Fail if required sections are missing.
3. Materialize agent-readable context when needed.

Phase 2: Agent Launch

1. Run health check.
2. Launch available agents.
3. Register every launched agent in evaluation-runtime.
4. If no agents are available, record agents_skipped_reason and continue.

Phase 3: Research And Feasibility

Required work:

• run ln-311-review-research-worker
• perform local feasibility validation in parallel while agents work

Minimum research lanes:

1. official documentation or standards
2. MCP Ref
3. Context7 for involved libraries
4. current web best-practice research

Feasibility checks:

• files exist
• no invalid overlap across hypotheses
• every hypothesis traces to profiler or research evidence
• unsupported removal hypotheses are flagged
• high-level fixes are preferred over low-level churn when evidence supports them

Phase 4: Merge

1. Sync agents at the merge barrier.
2. Merge:
   • local feasibility findings
   • research findings
   • agent findings
3. Reject unsupported suggestions.
4. Apply accepted corrections directly to context.md.

Phase 5: Refinement

Refinement uses a 2-stage state machine (see ln-316-review-refinement-worker):

• 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
• no skip when Codex is available except runtime-backed failure or disablement
• cleanup evidence is mandatory

Phase 6: Verdict

Possible verdicts:

• GO
• GO_WITH_CONCERNS
• NO_GO

NO_GO when:

• critical feasibility gaps remain
• research does not support the plan
• both local validation and agent review reject the plan

Phase 7: Self-Check

Required checks:

• context loaded and validated
• mandatory research completed
• local feasibility check completed
• all required agents resolved before merge
• merge summary exists
• refinement trace exists when Codex was available
• cleanup verified
• coordinator summary recorded

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
• Optimization context validated
• Mandatory research completed
• Agents launched or explicitly skipped
• Feasibility analysis completed
• Merge completed after agent barrier
• Refinement executed or explicitly justified
• Verdict issued
• 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 optimization-plan verdict.
