Skillbox is a library for AI agent skills that keeps them in one place and syncs them to the coding tools on your machines, such as Claude Code, Cursor and Codex.
You can import skills from your computer, add them from GitHub or GitLab by pasting a URL or owner/repo, or keep useful ones from the public Explore catalogue. Skillbox remembers where each skill came from, and collections group skills around a workflow such as frontend development or release preparation.
Activating a skill delivers it to the folders your tools read, either everywhere or only inside a specific project. Skills added from repositories keep following their source, and incoming versions are shown as diffs so you can promote them, skip them or set automatic updates.
Skillbox Trust checks new skill versions for prompt injection, data exfiltration, secrets and obfuscated code using Cisco Skill Scanner, with findings labelled in STRIDE and OWASP terms. Skills containing executables need your opt-in before they sync.
Other features include automatic maintenance that pauses unused installs and flags overlapping skills, Capture for turning a successful coding session into a reusable private skill, Skillbox AI for drafting and reviewing skills, Try in chat for testing a skill, and Skillbox Trim, which shortens noisy command output so agent sessions last longer.
A Mac app is available, and team workspaces let colleagues share a library, collections and required project standards.
Pricing: the Free plan costs nothing, needs no card and covers up to 3 devices and 100 followed sources. Individual is 6.99 GBP a month after a 7-day trial and adds Trim, Skillbox AI and Try in chat. Team is 12.99 GBP per active member a month.
It is suited to developers and engineering teams who use several AI coding agents and want one tidy, reviewed set of skills across machines and projects.
