Plugin Claude Code
Bundles 1 skill, 1 agent · 82 tokens together
Frontend-only Next.js 16 kit for apps backed by a separate API: three layer-owning agents (UI, tests, review), workflow commands, code-style rules, and a rules-install skill.
Skill Claude Code
Plan and document a new feature or a change to existing functionality — inspects the codebase, then writes docs/ /brief.md and plan.md. Use when the user describes something to build or change and wants it thought through and written down before implementation, or says "plan this", "write a brief", "spec this out".
