Creates infrastructure.md (always) and runbook.md (if hasDocker). DevOps documentation worker.

Generates Docker and docker-compose configuration for multi-container development

Executes all test suites and reports results with coverage

Test suite audit coordinator: automated + manual tests. Delegates to 7 workers (Business Logic, E2E, Value, Coverage, Isolation, Manual Quality, Structure). Output: docs/project/test_audit.md.

Creates test infrastructure with Vitest, xUnit, and pytest

Checks blocking IO in async, unnecessary allocations, sync sleep, string concat in loops, missing to_thread, redundant copies. Returns findings with severity and effort.

Orchestrates test planning pipeline (research → manual → auto tests). Coordinates ln-521, ln-522, ln-523.

Checks transaction scope, missing rollback handling, long-held transactions, trigger/notify interaction. Returns findings with severity, location, effort.

Checks cyclomatic complexity, nesting, long methods, god classes, method signatures, O(n²), N+1 queries, constants management. Returns findings.

Checks outdated packages, unused deps, reinvented wheels, vulnerability scan (CVE/CVSS). Supports mode: full | vulnerabilities_only.

Worker that runs existing tests to catch regressions. Auto-detects framework, reports pass/fail. No status changes or task creation.

Checks structured logging, health check endpoints, metrics collection, request tracing, log levels. Returns findings with severity, location, effort, recommendations.

Checks DRY (10 types), KISS/YAGNI, error handling, DI patterns. Returns findings with severity, location, effort, pattern_signature.

Checks redundant fetches, N-UPDATE/DELETE loops, unnecessary resolves, over-fetching, missing bulk operations, wrong caching scope. Returns findings with severity.

Creates 2 backend docs (api_spec.md, database_schema.md). Invoked when hasBackend or hasDatabase detected.

Orchestrates task operations. Analyzes Story, builds optimal plan (1-8 implementation tasks), delegates to ln-301-task-creator (CREATE/ADD) or ln-302-task-replanner (REPLAN). Auto-discovers team ID.

Creates 4 core project docs (requirements.md, architecture.md, tech_stack.md, patterns_catalog.md). ALWAYS created.

Checks layer leakage in method signatures, missing DTOs, entity leakage to API, inconsistent error contracts. Returns findings with penalty-based scoring.

Coordinates linters, pre-commit hooks, and test infrastructure setup

Audits architectural patterns against best practices. Maintains patterns catalog, calculates 4 scores per pattern. Output: patterns_catalog.md.
