It supports the use of deprecated repository references for Codex CLI, including workflows based on hooks.json layers, event matchers, stdin\/stdout contracts, and hook scripts.

Users are advised to test repositories from the Git root rather than assuming session current working directory (cwd). The documentation encourages minimal initial implementations and advises validating stdin\/stdout against event contracts. This approach aids in debugging and the resolution of repository-local commands, reinforcing hooks as workflow guardrails rather than security boundaries.\u003c\/p\u003e\n\u003c!-- mcpcart:static-blocks:start --\u003e\n\u003chr\u003e\n\u003ch3\u003eSource \u0026amp; Licence\u003c\/h3\u003e\n\u003cp\u003eThis package is built on open-source work published by \u003cstrong\u003enarumiruna\u003c\/strong\u003e (\u003ca href=\"https:\/\/github.com\/narumiruna\/skills\" rel=\"nofollow noopener\" target=\"_blank\"\u003enarumiruna\/skills\u003c\/a\u003e) and distributed under \u003cstrong\u003eMIT\u003c\/strong\u003e.
