What problem does it solve? Keeping up with upstream open-source projects and deciding which of their ideas are worth adopting is manual, noisy work. This Skill tracks repos you admire, investigates only what changed since the last run, and filters every change against your project's profile so only relevant, actionable ideas land in a ranked backlog. ## Core Features & Use Cases - Profile-based relevance filtering: Establishes a one-time project profile (architecture, goals, non-goals) used to reject upstream changes that don't map to your real needs. - Incremental investigation with watermarks: Clones watched repos into .tmp/ and diffs only commits since last_investigated_commit, with a baseline snapshot mode for first runs. - Ranked idea backlog: Writes scored, labelled ideas (change_type, effort, impact, risk, confidence) with a candidate → shortlisted → accepted → implemented lifecycle to docs/research/opensource-ideas.yaml, one doc per project or monorepo sub-project. - Use Case: After adding mattpocock/skills as a source, run an investigation to diff its recent commits, extract three applicable patterns, and get a top-5 shortlist of quick wins to adopt in your own repo. ## Quick Start Track the repository facebook/react for ideas we could borrow and scan it for recent changes worth adopting.
