Skillbox

Skillbox: one library for your AI coding agents' skills

Skillbox keeps your agent skills together, tracks their sources, scans each version for risky behavior, and delivers only the skills you choose to Claude Code, Cursor, Codex and 11 other coding tools on your machines.

How it works

• Bring skills in: import local skills, connect GitHub or GitLab, paste a repo link or README command, or keep one from Explore
• Choose what reaches your tools: a broad library, a small active set per tool or project
• Follow sources: upstream changes are held separately so you can compare and promote
• Sync everywhere: Skillbox for Mac or a terminal agent on macOS and Linux; Skillbox MCP for managing the library from your assistant

Skillbox Trust (every plan)

Checks instructions and bundled files for prompt injection, exfiltration, command injection, secrets and obfuscated code, labeled in STRIDE and OWASP terms, with Cisco Skill Scanner findings for public and shared skills. Approvals are tied to the exact version.

Skillbox Trim

Shortens noisy test, build, Git and search output before your agent reads it, keeps the full output on your machine, and reports tokens kept out of context. Works with Claude Code, Codex, Cursor, Gemini CLI, Copilot and more.
