--- name: ln-640-pattern-evolution-auditor-28e5820df751 description: "Use when auditing architectural patterns through the evaluation platform with mandatory best-practice research, coordinated pattern workers, and structured summaries." license: MIT --- > **Paths:** File paths (`shared/`, `references/`, `../ln-*`) are relative to skills repo root. **Type:** L2 Coordinator **Category:** 6XX Audit # Pattern Evolution Auditor ## 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/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) 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: ```text 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 **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 pattern audit result. ## References - Workers: `../ln-641-pattern-analyzer/SKILL.md`, `../ln-642-layer-boundary-auditor/SKILL.md`, `../ln-643-api-contract-auditor/SKILL.md`, `../ln-644-dependency-graph-auditor/SKILL.md`, `../ln-645-open-source-replacer/SKILL.md`, `../ln-646-project-structure-auditor/SKILL.md`, `../ln-647-env-config-auditor/SKILL.md` - Shared pattern refs: `references/layer_rules.md`, `references/pattern_library.md`, `references/scoring_rules.md` --- **Version:** 2.0.0 **Last Updated:** 2026-02-08 --- Source attribution: boisenoise Original project: https://github.com/boisenoise/skills-collections/blob/e8c4cb5cbafb600fab08ffdf4b23359c9f608d9d/skills/levn-ln-640-pattern-evolution-auditor/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
