Pattern Evolution Auditor

Mandatory Read

MANDATORY READ: Load references/evaluation_coordinator_runtime_contract.md, references/evaluation_summary_contract.md, references/evaluation_research_contract.md
MANDATORY READ: Load references/audit_final_report_contract.md
MANDATORY READ: Load references/architecture_audit_worker_boundaries.md
MANDATORY READ: Load references/research_tool_fallback.md
Conditional read: load references/epistemic_protocol.md only when source confidence or claim uncertainty affects issue validation.

Purpose

audit architecture/design evolution: pattern fitness, layer ownership, service/API contracts, dependency topology, modernization, physical structure, and configuration boundaries

coordinate exactly ln-641 through ln-647

require research before pattern scoring

Worker Invocation (MANDATORY)

Host Skill Invocation: Skill(skill: "...", args: "...") is mandatory delegation.

Claude: call the Skill tool exactly as shown.

Codex: if no Skill tool exists, locate the named skill in available skills, read its SKILL.md, treat args as $ARGUMENTS, execute that skill workflow, then return here with its result/artifact.

Do not inline worker logic or mark the worker complete without executing the target skill.

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

TodoWrite format (mandatory):

Resolve audit scope and build manifest

Load architecture patterns and layers

Run best-practice research

Run boundary and contract audits

Analyze pattern compliance and gaps

Aggregate worker findings

Generate final audit report and remediation plan

Verify cleanup and self-check

Representative invocations:

Skill(skill: "ln-641-pattern-fitness-auditor", args: "{scope}")
Skill(skill: "ln-642-layer-ownership-boundary-auditor", args: "{scope}")
Skill(skill: "ln-643-api-contract-auditor", args: "{scope}")
Skill(skill: "ln-644-dependency-topology-auditor", args: "{scope}")
Skill(skill: "ln-645-architecture-modernization-auditor", args: "{scope}")
Skill(skill: "ln-646-project-structure-auditor", args: "{scope}")
Skill(skill: "ln-647-configuration-boundary-auditor", args: "{scope}")

Workflow

Start evaluation-runtime.

Discover candidate patterns and applicability.

Run mandatory research first:

official docs or standards

MCP Ref

Context7 when library/framework patterns are involved

current web best-practice research

Run boundary audits before pattern scoring.

Run pattern analysis only after boundary results and research exist.

Aggregate scores and worker findings by reading every worker report_path, normalizing actions from references/architecture_audit_worker_boundaries.md, deduplicating issues, resolving worker conflicts, and validating actionable problems against references/evaluation_research_contract.md.

Write .hex-skills/runtime-artifacts/runs/{run_id}/audit-report/ln-640--final-report.md with remediation plan per references/audit_final_report_contract.md.

Remove temporary worker markdown reports and record cleanup evidence.

Write the evaluation-coordinator summary with report_path set to the final report.

Definition of Done

 Evaluation runtime started

 Pattern applicability resolved

 Best-practice research completed

 Boundary audit summaries recorded

 Pattern analysis summaries recorded

 Worker set remained exactly ln-641 through ln-647

 Worker conflicts resolved with architecture_audit_worker_boundaries.md

 Final report and remediation plan written

 Temporary worker markdown reports removed

 evaluation-coordinator summary written

 Runtime completed

Meta-Analysis

Optional reference: load references/meta_analysis_protocol.md only when the user asks for post-run meta-analysis or protocol-formatted run reflection.

When requested after the coordinator run, analyze the session per protocol section 7 and include the protocol-formatted output with the final pattern audit result.
