Agent Skills: Pre-Commit Hooks

Pre-Commit Hooks

This project uses prek as the pre-commit hook runner. Do NOT use pre-commit run — always use prek run.

Running Hooks

Run all hooks across all files:

prek run --all-files

Run hooks on specific files:

prek run --files path/to/file.rs

Run hooks on files changed since last commit:

prek run --last-commit

When to Run

Always run prek run --all-files after implementing code and before committing, as part of the STDD workflow:

1. Tests pass (GREEN)
2. Run prek run --all-files ← here
3. Fix any issues raised
4. Commit

Installing Hooks

On a fresh checkout, install the git hooks with:

just setup

Which runs:

prek install
prek install --hook-type commit-msg
prek install --hook-type pre-push

Hook Stages

Hooks are split across two stages:

• pre-commit (prek install): formatting, linting, style checks — run on every commit
• pre-push (prek install --hook-type pre-push): heavier checks like cargo deny — run on push
