setup-git-hooks

A command that installs Git hooks, which are scripts Git runs at events such as commits and pushes.

In plain words
What is it for?
Use it to detect the project type and existing checks, configure them interactively, and install pre-commit, pre-push, or commit-message checks.
Why use it?
It catches formatting, lint, test, and commit-message problems before changes are committed or pushed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

setup-git-hooks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/wrangler:setting-up-git-hooks

Set up Git hooks for automated testing and code quality enforcement.

Description

This command helps you configure and install Git hooks in your project to enforce testing and code quality standards before commits and pushes. It provides an interactive setup experience with smart project detection.

What It Does

  1. Detects your project type (JavaScript, Python, Go, etc.)
  2. Finds existing test/lint/format commands from project files
  3. Asks configuration questions with sensible defaults
  4. Generates hook configuration (.wrangler/config/hooks-config.json)
  5. Installs hooks to .git/hooks/ or .wrangler/config/git-hooks/
  6. Creates documentation templates (TESTING.md, security checklist, etc.)

Usage

Simply run the command:

/wrangler:setting-up-git-hooks

Follow the interactive prompts to configure your hooks.

Hooks Installed

Hook When What It Does
pre-commit Before each commit Runs formatter, linter, unit tests
pre-push Before push to protected branches Runs full test suite
commit-msg On commit (optional) Validates commit message format

Installation Patterns

Pattern A: Direct Installation (Default)

Hooks installed directly to .git/hooks/. Configuration in .wrangler/config/hooks-config.json.

Best for: Individual developers, small teams

Pattern B: Version-Controlled

Hooks stored in .wrangler/config/git-hooks/ and symlinked via install script.

Best for: Teams that want hooks in version control, consistent setup across team

Bypass Mechanism

For TDD RED phase or emergency fixes:

WRANGLER_SKIP_HOOKS=1 git commit -m "WIP: failing test for feature X"

Note: This bypass is only available to humans. AI agents cannot set environment variables, ensuring they always follow the enforcement rules.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
