Plans automated tests (E2E/Integration/Unit) using Risk-Based Testing after manual testing. Calculates priorities, delegates to ln-301-task-creator.

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

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

Executes Story Finalizer test tasks (label "tests") from Todo -> To Review. Enforces risk-based limits and priority.

Researches real-world problems, competitor solutions, and customer complaints before test planning. Posts findings as Linear comment for ln-522 and ln-523.

Creates Stories from IDEAL plan (CREATE) or appends user-requested Stories (ADD). Generates 9-section documents, validates INVEST, creates in Linear.

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

Story-level quality orchestrator with 4-level Gate (PASS/CONCERNS/FAIL/WAIVED) and Quality Score. Delegates to ln-510 (quality) and ln-520 (tests), calculates final verdict.

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

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

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

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

Configures ESLint, Prettier, Ruff, mypy, and .NET analyzers

Creates design_guidelines.md for frontend projects. Invoked when hasFrontend detected.

Fixes tasks in To Rework and returns them to To Review. Applies reviewer feedback only for the selected task.

Coordinates 9 audit workers (ln-621..ln-629) in parallel. Research best practices, delegate, aggregate into docs/project/codebase_audit.md.

Universal platform artifact cleaner: Replit, StackBlitz, CodeSandbox, Glitch

Analyzes single pattern implementation, calculates 4 scores (compliance, completeness, quality, implementation), identifies gaps. Invoked by ln-640 or standalone.

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.

CREATE/REPLAN Epics from scope (3-7 Epics). Batch Preview + Auto-extraction. Decompose-First Pattern. Auto-discovers team ID.
