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

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.

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

Generates .NET Clean Architecture backend structure from entity definitions

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

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

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

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

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

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

Checks outdated packages, unused deps, reinvented wheels, vulnerability scan (CVE/CVSS).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

Builds all detected projects and verifies successful compilation

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

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

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

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

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

Creates test documentation (testing-strategy.md + tests/README.md). Establishes testing philosophy and Story-Level Test Task Pattern.
