design-playbook

Agent plugin: Design I/O for product UI (Claude Code / Codex).

Declarations + contracts — not a style CSV pack. Compose with ui-ux-pro-max and Anthropic frontend-design for aesthetics; this package owns pipeline and acceptance.

Install (Claude Code)

Path of record (published) - the marketplace catalog lives at the repo root, not in this package:

/plugin marketplace add https://github.com/Bandersnatch0x/design-playbook.git
/plugin install design-playbook@design-playbook

Local dev / self-test:

claude --plugin-dir /packages/design-playbook      # dev load, no install
# or local marketplace (point at the repo root, where the catalog lives)
/plugin marketplace add 
/plugin install design-playbook@design-playbook

Install (Codex)

Same GitHub repo / monorepo root catalog. Codex-native manifest lives at .codex-plugin/ (MCP uses relative paths).

codex plugin marketplace add Bandersnatch0x/design-playbook
codex plugin add design-playbook@design-playbook

Local monorepo:

codex plugin marketplace add 
codex plugin add design-playbook@design-playbook

Details + skills-only fallback: codex/AGENTS.md.
