What it does
Prek is an agent skill from bastani-inc/atomic. Use when setting up or running hooks with prek in any repository. prek is a Rust drop-in alternative to pre-commit for running Git hooks that check, format, lint, and validate code and repository files. Prefer it when speed, workspace mode, built-in hooks, shared toolchains, or native TOML configuration matter.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Linting and formatting. It works with Git and Rust. The repository describes itself as: The verifiable coding agent runtime. Define your coding agent's process in natural language with stages, checks, and approval gates instead of hoping it follows your…
When your agent uses it
- Running hooks with prek in any repository
- Tasks that involve Linting and formatting
Example prompts
- “/prek”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Check whether the repo already has .pre-commit-config.yaml or .pre-commit-config.yml.
- If it does, usually keep that config and switch the commands from pre-commit to prek.
- If migrating from pre-commit, reinstall the Git shims with prek install -f.
- If it does not, prefer creating prek.toml for a fresh setup.
- Install prek.
- Validate the config with prek validate-config.
- Install the Git shims and prepare hook environments with prek install --prepare-hooks.
- Run everything once with prek run --all-files.
- For monorepos, consider nested configs, .prekignore, and orphan: true.
What it can do on your machine
Read from SKILL.md and the folder at commit ad79904. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
cargouvbrewmise
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
Also links to:
prek.j178.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Prek loads about 2.1k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 820 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 820 words (~2,072 tokens).
“Use this skill when the user wants to set up or run Git hooks with prek.”
