Prek

Skill MAHDTech/agent-skills/skills/tooling/prek

Run pre-commit hooks using the prek CLI tool. Differentiates between 'pre-commit' (the git hooks concept/lifecycle stage) and 'prek' (the actual binary command; pre-commit CLI is deprecated, use prek). Use when you need to run, configure, check, or troubleshoot git pre-commit hooks.From its SKILL.md

Prek (Pre-commit)

prek is a fast Git hook manager written in Rust, designed as a drop-in replacement for the deprecated pre-commit CLI tool.

[!IMPORTANT] Command Line & Package Discrepancy: The CLI binary is prek, NOT pre-commit. The pre-commit CLI tool is deprecated and MUST NOT be used.

Key Differences

Git concept / stage: "pre-commit" refers strictly to the Git lifecycle hook stage (e.g. .pre-commit-config.yaml).
Legacy CLI Tool (DEPRECATED): The Python-based pre-commit CLI tool is deprecated. NEVER add pkgs.pre-commit or pre-commit package/input to devenv.nix or package managers.
Active Hook Runner: prek is the CLI binary used to run and configure pre-commit hooks.

Running Hooks

When working inside a devenv shell, run:

SECRETSPEC_REASON="running pre-commit hooks" devenv --no-tui shell -- prek run -a

If not using devenv, run:

prek run -a

Use -a or --all-files to run hooks against all files in the repository.

Commands

prek run: Run hooks against modified files.
prek run -a: Run hooks against all files.
prek install: Install prek Git shims into Git's hooks directory.
prek uninstall: Uninstall prek Git shims.
prek validate-config: Validate configuration files (prek.toml or .pre-commit-config.yaml).
prek cache: Manage the prek cache (e.g., prek cache clean).
