Audit repository test suites for low-value, brittle, duplicative, or AI-generated tests. Use when Codex needs to review tests across a single project or monorepo, identify tests to delete or merge, upgrade weak tests, consolidate repeated setup into helpers, or produce a precise test quality cleanup plan.
Use when you have a plan directory from decomposing-specs and need to execute it — loads phases on demand, dispatches phase-elaborator for sketched phases, runs implementers with size-scaled phase reviews, and validates the full spec at the end
Use when you have a design spec from writing-specs and need to break it into an implementable, phased task plan with behavior-focused verification before writing any code
Use when given a GitHub issue URL to autonomously implement — forks the repo, writes a spec if needed, decomposes into tasks, implements, and opens a PR
Use when given a GitHub issue URL to autonomously implement — forks the repo, writes a spec if needed, decomposes into tasks, implements, and opens a PR
Use when a GitHub issue receives new comments during autonomous work — decides whether to update the spec and re-decompose, or just make the change inline
Use when configuring a repository to run with Code Factory — creates `.code-factory/config.toml`, sets up a devcontainer if missing, and validates that build/lint/test work inside it. Triggers on "setup code factory", "configure code factory", "onboard this repo to code factory".
Use when starting any feature, system change, or bugfix that requires architectural decisions — before writing implementation plans or code. Triggers on new projects, multi-component changes, API design, or when the user says "design", "spec", or "architecture".
