One library for your AI skills, synced to every agent
Skillbox keeps your AI skills in one library and syncs them to Claude Code, Cursor and Codex. Follow GitHub sources, review diffs, and scan each version for prompt injection. Trim shortens noisy command output so sessions last longer.
Hi Product Hunt, I'm Adenekan Wonderful, the maker of Skillbox.
I built this because my AI skills were everywhere. A few lived in GitHub repos, some sat inside project folders, and some were installed for Claude Code but missing from Cursor. A better version of one would turn up and I'd have no idea. Copying files was easy. Knowing what I had, where it came from, whether it had changed, and whether it was safe was the hard part.
So Skillbox does four things:
One library, and a smaller active set. Keep everything you've collected, and deliver only what each tool or project needs. Every skill your agent loads costs context, so we don't treat "saved" as "installed".
Sources stay attached. Skills added from GitHub or GitLab keep following their source. When one changes, you see the diff and decide whether to take it.
Trust, per version. Each version is scanned for prompt injection, data exfiltration, command injection, hardcoded secrets and obfuscated code, including by Cisco's Skill Scanner. Approval is tied to the exact content that was reviewed, so it doesn't carry over silently when a skill changes. A passing check is evidence, not a guarantee.
Trim. It shortens noisy test, git and build output before your agent reads it. The full output stays one command away, and your sessions last longer.
It syncs across Claude Code, Cursor and Codex. Trim currently covers more than that, but session insights are deepest on Claude Code.
There's a permanent free plan for the library, sync, updates and Trust. Trim and AI features are on Individual, with a 7-day trial.
I'd love to hear how your skills are scattered today, and what would make you trust a skill you didn't write. I'm here all day and will reply to everything.
