What problem does it solve? In a large bun/turbo monorepo with 20+ packages and 5 apps, developers often edit the wrong layer, hit stale dist/ builds, or run tests that silently skip packages. This Skill tells you exactly which package or app owns a behaviour and which commands to run. ## Core Features & Use Cases - Ownership Map: A lookup table routing behaviours (chat UI, document editor, search, PDF extraction, YouTube transcripts, MCP server) to the correct package and its dedicated skill. - App Coverage: Documents the five apps (Next.js web, Tauri desktop, WXT browser extension, VS Code extension, LobeHub build) that have no package skill of their own, including the Hocuspocus collaboration server inside the web app. - Build & Test Guidance: Explains the workspace build-order trap, why root bun run test skips some packages, and how to add a new workspace package. - Use Case: You changed research-agent-ui but the web app shows old behaviour — the Skill explains the app imports built dist/ output and tells you to run the prebuild script. ## Quick Start Ask which package owns the search results UI in the QwkSearch monorepo and how to rebuild it so the web app picks up the change.
