Provides a collection of skills and agents for tech research, documentation generation, codebase navigation, performance review, and design prototyping. Includes tools for answering architecture questions, creating CLAUDE.md files, generating PRDs, mining session logs, reviewing React/Next.js performance, cloning website UIs, and fact-checking recommendations.
Local-only repo research for caveman-search. Scans the current repository for the stack, existing patterns relevant to a topic, and conventions. Returns a terse digest plus a local_coverage count that feeds the escalation gate. Never touches the web.
Adversarial verification for caveman-search, spawned only when --verify is passed. Takes one recommendation claim and tries to refute it — is it the right pick, still current, and does it actually do what's claimed. Returns a verdict (holds / weakened / wrong) with evidence and a correction if wrong.
External research for caveman-search. Finds the specific, current tools/libraries/APIs for a topic via web search and official docs, runs a mandatory deprecation/existence gate on every candidate, and returns a terse digest with one reason + status + link per recommendation. Self-tags each recommendation as a verifiable claim.
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 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.
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 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.
