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:

• PHASE_0_CONFIG

• PHASE_1_DISCOVERY

• PHASE_2_RESEARCH

• PHASE_3_BOUNDARY_AUDITS

• PHASE_4_PATTERN_ANALYSIS

• PHASE_5_AGGREGATE

• PHASE_6_REPORT

• 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:

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

• 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 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.
