# Setup Pre-commit Hooks (deprecated) **This skill was renamed to `setup-git-hooks` in 0.1.29. Invoke that instead.** Do not follow any procedure from this file. It retains no content — it exists solely so that an invocation of the old name yields a pointer rather than silence. ## Why it was renamed The old name was wrong on two axes at once: - **It named one of the two stages.** The skill's thesis is the two-stage split — fast checks on commit, thorough checks on push. The pre-push stage is roughly a third of the content and carries the checks that catch the expensive defects. - **It named one of the two supported hook managers.** The skill documents both `pre-commit` and `lefthook`; its "Install Hook Framework" step mentions `lefthook` more often than `pre-commit`, and roughly half the skill (`.editorconfig`, secret-detection architecture, `.gitignore` hardening, multi-remote protection) involves no hook manager at all. The practical effect was that maintainers on Elixir, Go or Rust projects read "pre-commit", correctly inferred "that is the Python hook framework", and never reached the content that had nothing to do with it. See workspace ADR-0013. ## Migration Replace any invocation of `setup-pre-commit` with `setup-git-hooks`. There is no behavioural change — same workflow, same steps, same outputs. ## Removal This stub will be removed at **0.2.0**. It exists only for the deprecation window, because the skill, plugin and marketplace manifests provide
