Reusable pre-commit hooks for GitOps, security, and multi-agent workflows.

Add to your .pre-commit-config.yaml:

- repo: https://github.com/injectedfusion/pre-commit-hooks
  rev: v0.1.0
  hooks:
    - id: check-branch-staleness
    - id: trivy-deps
    - id: no-hardcoded-secrets

Then install:

pip install pre-commit  # if not already installed
pre-commit install

Some hooks (like require-signed-commits) enforce personal discipline that shouldn't be imposed on teammates. Use a global git hook instead — fires on every repo with zero per-repo setup:

mkdir -p ~/.config/git/hooks
git config --global core.hooksPath ~/.config/git/hooks

Create ~/.config/git/hooks/pre-commit:

#!/usr/bin/env bash
set -euo pipefail

# Personal check (e.g. signing)
gpgsign="$(git config --get commit.gpgsign 2>/dev/null || echo 'false')"
if [[ "$gpgsign" != "true" ]]; then
  echo "✗ Unsigned commit blocked: commit.gpgsign is not set to true"
  exit 1
fi
signingkey="$(git config --get user.signingkey 2>/dev/null || echo '')"
if [[ -z "$signingkey" ]]; then
  echo "✗ Unsigned commit blocked: user.signingkey is not set"
  exit 1
fi

# Chain to repo pre-commit config if present
repo_root="$(git rev-parse --show-toplevel)"
for config in "$repo_root/.pre-commit-config.local.yaml" "$repo_root/.pre-commit-config.yaml"; do
  if [[ -f "$config" ]]; then
    exec pre-commit run --config "$config" --hook-stage pre-commit
  fi
done

chmod +x ~/.config/git/hooks/pre-commit

Fetches the remote default branch and fails if the current branch is behind. Auto-detects the default branch (main, develop, master, etc.) — no configuration needed.

Designed for workflows where multiple developers or AI agents work concurrently on the same repo, preventing commits against stale state.

Behavior:

• Skips on the default branch itself
• Gracefully skips if offline
• Shows which commits are missing

Scans dependency lockfiles for known vulnerabilities using Trivy. Triggers on changes to:

Cargo.lock, package-lock.json, go.sum, requirements.txt, poetry.lock, pnpm-lock.yaml, yarn.lock, Gemfile.lock, composer.lock

Requires: trivy installed locally (brew install trivy).

Regex-based detection of hardcoded credentials in YAML files. Catches patterns like:

password: "AcT3kR9base64string..."
api_key: 'longSecretValue123...'

Ignores common templating patterns ($__env{}, secretRef, existingSecret).

• pre-commit >= 2.0
• git (for check-branch-staleness)
• trivy (for trivy-deps, optional — hook skips gracefully if missing)
