Ln 404 Test Executor

Executes test tasks from your Story workflow, moving them from Todo through implementation to To Review. It's built for test execution only, not feature work. The skill enforces risk-based limits (priority thresholds, usefulness checks), blocks infrastructure and performance tests to keep focus on business logic, and includes a detailed failure analysis protocol that stops you from blindly fixing assertions when the real bug is in the code. Uses hex-line MCP tools when available for faster file operations. Leaves everything uncommitted for reviewer approval. If you're running a multi-worker Story setup where test tasks split from implementation tasks, this handles the test lane.
