Is it possible to add Anthropic sdlc playbook inside agent-skills?

So it should follow these guides or something it's already there in agent-skills

The issue requests adding the Anthropic SDLC playbook and links to the source. No files or tests are named, so start by inspecting the repo’s documentation layout (README plus any skill/playbook index) to see how similar guides are organized. Add the new playbook entry in the same format and register it in the same listing/manifest it uses. Done when the playbook is discoverable in the docs alongside existing skills.
