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/research_tool_fallback.md

Purpose

• audit implemented architectural patterns against current best practices
• coordinate ln-641 through ln-647
• require research before pattern scoring

Runtime Contract

Runtime family:

• evaluation-runtime

Identifier:

• pattern-audit

Phase order:

1. PHASE_0_CONFIG
2. PHASE_1_DISCOVERY
3. PHASE_2_RESEARCH
4. PHASE_3_BOUNDARY_AUDITS
5. PHASE_4_PATTERN_ANALYSIS
6. PHASE_5_AGGREGATE
7. PHASE_6_REPORT
8. PHASE_7_SELF_CHECK

Worker Set

• ln-641-pattern-analyzer
• ln-642-layer-boundary-auditor
• ln-643-api-contract-auditor
• ln-644-dependency-graph-auditor
• ln-645-open-source-replacer
• ln-646-project-structure-auditor
• ln-647-env-config-auditor

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 audit report
• Verify cleanup and self-check

Representative invocations:

Skill(skill: "ln-641-pattern-analyzer", args: "{scope}")
Skill(skill: "ln-642-layer-boundary-auditor", args: "{scope}")
Skill(skill: "ln-643-api-contract-auditor", args: "{scope}")
Skill(skill: "ln-644-dependency-graph-auditor", args: "{scope}")
Skill(skill: "ln-645-open-source-replacer", args: "{scope}")
Skill(skill: "ln-646-project-structure-auditor", args: "{scope}")
Skill(skill: "ln-647-env-config-auditor", args: "{scope}")

Workflow

1. Start evaluation-runtime.
2. Discover candidate patterns and applicability.
3. Run mandatory research first:
   • official docs or standards
   • MCP Ref
   • Context7 when library/framework patterns are involved
   • current web best-practice research
4. Run boundary audits before pattern scoring.
5. Run pattern analysis only after boundary results and research exist.
6. Aggregate scores and produce the final pattern report.

Definition of Done

• Evaluation runtime started
• Pattern applicability resolved
• Best-practice research completed
• Boundary audit summaries recorded
• Pattern analysis summaries recorded
• Final report written
• 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.
