Build, launch, and drive the piano roll app to verify changes end-to-end (dev server + Playwright with the preinstalled Chromium).

A emantic RAG store partitioned by PROJECT. One store on disk; every project is its own embedded + cross-encoder-reranked index, and the active project is auto-resolved from the working directory (so an agent working inside a repo just gets that repo's retrieval, hsci-style). Supports per-project search AND global cross-project search that merges + reranks hits from every project. Use this whenever the user wants to "search my docs/notes/ codebase", build a local RAG / retrieval index, "index this project", give a local LLM or agent grounded project-scoped retrieval, set up a vector DB over files, ask questions across one repo or across all their projects, or wire semantic search into an MCP — even if they don't say the word "vector". Trigger on phrases like "semantic search over X", "index this repo", "RAG for my projects", "search across all my projects", "vector DB keyed by project", "what did we decide in project", or "let the agent search the current project".

Build production-quality three.js WebGL scenes with vanilla three.js (no R3F). Use this skill whenever the user mentions three.js, WebGL, 3D scenes in the browser, isometric games, voxel worlds, infinite/endless scrollable 3D, procedural geometry, instancing/BatchedMesh, billboards, particle systems, shader effects, glitch effects, bloom, lens flares, god rays, depth of field, chromatic aberration, stereoscopy, anaglyph, film grain, HUD transitions, camera controls (orbit/follow/pan-zoom), touch-friendly 3D controls, three.js performance optimization, draw-call reduction, LOD, post-processing chains, EffectComposer, GLSL ShaderMaterial, or LLM-driven programmatic generation of three.js content. Also trigger when the user wants to build a 3D web experience, mounts a `canvas` for three.js, asks "how do I make this run smooth", needs frame-rate capping, or wants to generate 3D assets from text prompts via Gemini / ai-sdk function tools.
