Agent Hooks Setup

If your AI coding assistant supports lifecycle hooks, configure these for this repo.

HookCommandPurpose
afterFileEditscripts/agent-hooks/format.shAuto-format files after AI edits
afterFileEditscripts/agent-hooks/yarn-install.shRun corepack yarn install when package.json changes
stopscripts/agent-hooks/sync-git-branches.shPrune stale refs and delete integrated temporary task branches
stopscripts/agent-hooks/verify.shHard-gate targeted build verification, lint, typecheck, and format checks; keep yarn npm audit informational and run yarn knip separately as an advisory audit when dependencies/imports change

Why​

  • Consistent formatting
  • Lockfile stays in sync
  • Workspace-relevant build/lint/type issues caught early without forcing the full multi-locale docs build on every task
  • Security visibility via yarn npm audit
  • Dependency/import drift can be checked with yarn knip without turning it into a noisy global stop hook
  • One shared hook implementation for both Codex and Cursor
  • Temporary task branches stay aligned with the repo's worktree workflow

Example Hook Scripts​

Format Hook​

#!/bin/bash
# Auto-format JS/TS files after AI edits
# Hook receives JSON via stdin with file_path

input=$(cat)
file_path=$(echo "$input" | grep -o '"file_path"[[:space:]]*:[[:space:]]*"[^"]*"' | sed 's/.*:.*"\([^"]*\)"/\1/')

case "$file_path" in
  *.js|*.jsx|*.ts|*.tsx|*.mjs|*.cjs|*.json|*.css) corepack yarn exec oxfmt "$file_path" 2>/dev/null ;;
esac
exit 0

Verify Hook​

#!/bin/bash
# Run targeted build verification, lint, typecheck, format check, and security audit when agent finishes

cat > /dev/null  # consume stdin
status=0
corepack yarn build:verify || status=1
corepack yarn lint || status=1
corepack yarn typecheck || status=1
corepack yarn format:check || status=1
echo "=== yarn npm audit ===" && (corepack yarn npm audit || true)  # informational
exit $status

By default, scripts/agent-hooks/verify.sh exits non-zero when a required check fails. Set AGENT_VERIFY_MODE=advisory only when you intentionally need signal from a broken tree without blocking the hook. Keep yarn knip out of the hard gate unless the repo explicitly decides to fail on advisory import/dependency issues.

Yarn Install Hook​

#!/bin/bash
# Run corepack yarn install when package.json is changed
# Hook receives JSON via stdin with file_path

input=$(cat)
file_path=$(echo "$input" | grep -o '"file_path"[[:space:]]*:[[:space:]]*"[^"]*"' | sed 's/.*:.*"\([^"]*\)"/\1/')

if [ -z "$file_path" ]; then
  exit 0
fi

if [ "$file_path" = "package.json" ]; then
  cd "$(dirname "$0")/../.." || exit 0
  echo "package.json changed - running corepack yarn install to update yarn.lock..."
  corepack yarn install
fi

exit 0

Configure hook wiring according to your agent tool docs (hooks.json, equivalent, etc.).

In this repo, .codex/hooks/*.sh and .cursor/hooks/*.sh should stay as thin wrappers that delegate to the shared implementations under scripts/agent-hooks/.
