Use when the user hands you a vague or half-formed feature ask and wants it turned into a lightweight PRD, or asks to "write a PRD", "spec this feature", "flesh this out", or invokes /lite-prd. Interviews the user by traversing a design tree of clarifying questions, persists every Q&A round to the repo, and emits a lite-prd.md.
Review React/Next.js code against the real vercel-react-best-practices skill, backlog the performance findings keyed to actual rule ids + impact tiers, rank the most over-subscribed tiers, then fix + test the top N in isolated worktrees. Use when the user wants to systematically harvest and fix React/Next.js PERFORMANCE refactors (waterfalls, bundle size, RSC fetching, re-renders, JS perf), or says "react refactor tournament", "find React performance refactors", "/react-refactor-tournament".
Mine recent Claude Code sessions for non-obvious, multi-file CLAUDE.md candidates, adversarially verify them, and propose paste-ready additions. Use when the user wants to harvest documentation-worthy patterns/gotchas from past coding sessions into a project's CLAUDE.md, or says "mine my sessions for CLAUDE.md", "what should be in my CLAUDE.md", "/mine-claude-md".
Use when the user wants a terse, opinionated, research-backed answer to a "what tech/tools/stack do I need for X" question, or asks how to approach building something. Triggers on "caveman search", "caveman research", "/caveman-search", and on tooling/architecture questions where the user wants the direct answer, not a survey. Runs decomposed research (local repo + live web), verifies, and renders in a compressed caveman voice that leads with the load-bearing truth.
Set up hierarchical Intent Layer (AGENTS.md files) for codebases. Use when initializing a new project, adding context infrastructure to an existing repo, user asks to set up AGENTS.md, add intent layer, make agents understand the codebase, or scaffolding AI-friendly project documentation.
Use when the user wants to create, draft, or scaffold a CLAUDE.md (or AGENTS.md) file for their project. Triggers on "scaffold CLAUDE.md", "write a CLAUDE.md", "set up CLAUDE.md", "/scaffold-claude", or any request to bootstrap project-level Claude/agent instructions. Produces a scratchpad draft that captures edge cases and tribal knowledge — not derivable facts.
Use when user provides a URL and wants to replicate or clone a website's UI, design, or visual style for their own product. Entry point for the full 4-phase SRIP pipeline.
Use when translating a PRD, feature spec, or raw product idea into screen-level prompts for web UX generators (Google Stitch, Figma AI, Pencil.dev, Claude Design, v0, or similar). Use before creating visual mockups or wireframes.
