work-loop

Use this skill whenever you're implementing a non-trivial change -- a feature, a multi-file bug fix, a refactor, a migration, a framework or dependency upgrade, a schema or API change, performance work, an infrastructure or build-system edit, or anything spec-driven. Also triggered by argless resume phrases -- "resume", "continue", "keep going", "pick up where I left off", "let's get going" (bare phrases only; "resume the X project" or "resume the X investigation" routes to desk-research-project-status). It enforces the project's plan -> execute -> self-review -> fix loop with mechanical gates (lint, typecheck, tests) and adversarial review. Default to this skill for any task larger than a one-line edit.
