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

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

CREATE/REPLAN Stories for Epic (5-10 Stories). Multi-epic routing: auto-groups Stories by correct Epic. Delegates ln-001 for standards research. Self-Check phase.

Generates .NET Clean Architecture backend structure from entity definitions

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

Coordinates logging, error handling, CORS, health checks, and API docs

Updates ALL task types (implementation/refactoring/test). Compares IDEAL plan vs existing tasks, categorizes KEEP/UPDATE/OBSOLETE/CREATE, applies changes in Linear and kanban.

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

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

Coordinates security scanning (secrets + deps). Delegates to ln-761 + ln-625(mode=vulnerabilities_only). Generates SECURITY.md, pre-commit hooks, CI workflow.

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

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Checks outdated packages, unused deps, reinvented wheels, vulnerability scan (CVE/CVSS).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.

Coordinates project structure: SCAFFOLD new or RESTRUCTURE existing to Clean Architecture

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

Research best practices via MCP Ref/Context7/WebSearch and create documentation (guide/manual/ADR/research). Single research, multiple output types.

E2E Critical Coverage audit worker. Validates E2E coverage for critical paths (Money 20+, Security 20+, Data 15+). Pure risk-based - no pyramid percentages.

Creates test infrastructure with Vitest, xUnit, and pytest

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

Scans codebase for hardcoded secrets. Returns normalized findings with severity and remediation guidance. Pre-commit hook integration.
