Hooks are supported both by GitHub Copilot (e.g. in VSCode) and Claude Code.

VSCode specifically reads hook configuration from .github/hooks/*.json files among others.

Hook json files can point to scripts in any location with relative paths, and those files make integral part of a hook - they must also be portable if we make hooks installable via apm.

APM could help distribute Hooks as primitives in a portable and composable way across projects.
