Compare your skill library against everything in the AI for Impact Hub, find the skills worth adding, and sync the newer Hub versions into the ones you already have, without losing your customisations.
Download the file and drop it into your skills folder, or save it from Cowork. Then say "compare my skills to the Hub". Setup for every tool is below.
It reads your library, fetches the current Hub catalogue, and sorts everything into four buckets: up to date, update available, gap, and your own.
You get a report, then it adds or syncs only what you approve, one file at a time, with a backup made before it touches anything.
Everything in your library, sorted into four clear buckets so you can see exactly where you stand against the Hub.
Skills in the Hub catalogue that fit your goals but are missing from your library. Each one comes with a short note on why it might help, so you can decide what is worth adding.
Where the Hub has moved a skill forward, it merges the improvement into your version and keeps your customisations. You see the exact change before anything is applied.
Skills that already match the current Hub version. No action, no noise. It tells you they are current and moves on, so your attention stays on what matters.
Skills you built yourself that do not come from the Hub. These are recognised as your own and left untouched, never flagged as a gap or a thing to fix.
Pick the path that matches where you work. You only need the skill and Python, which almost every Claude environment already has.
~/.claude/skills/hub-gap-finder (or your project's .claude/skills/)..skill file and click Save skill to install.python3 scripts/compare_to_hub.py <your_skills_folder>python3 scripts/build_report.py hub_gap_data.json and open the HTML.It never overwrites or deletes your work. Syncing merges the Hub improvement in and keeps your customisations, so nothing you wrote is lost. Every change is shown first, backed up, and applied only on your yes. You decide, and you own every file.
