To start, copy and send this to your AI agent:

Install skillsafe from https://skillsafe.ai/skill.md

Works with Claude Code, Cursor, Windsurf, Codex CLI, and more

Why does this exist?

AI skills can run arbitrary code on your machine. Most are installed from random GitHub repos with zero verification — no signature, no scan, no audit trail. SkillSafe fixes that.

Dual-Side Verification

Sharers scan before sharing. Consumers re-scan after download. The server compares both reports — tampered skills are flagged immediately.

Cryptographic Tree Hashes

Every file is SHA-256 content-addressed. The immutable tree hash means if a single byte changes, verification fails with a critical verdict.

Semantic Versioning

Strict semver enforcement, version yanking, changelogs, and delta downloads. Install exactly the version you need, every time.

Encrypted Vault

Back up skill configurations with client-side AES-256-GCM encryption. The server stores only ciphertext — zero-knowledge storage.

Built for AI Tools

Works with any AI coding tool that supports skills. One registry, universal compatibility across all platforms.

Free to Use

Back up your own skills with 10 MB storage free. Pay for more storage and priority verification. Dedicated enterprise skill sharing management.

Quick Start

Install

Send this to your AI coding tool:

Install skillsafe from https://skillsafe.ai/skill.md

Your AI tool reads the skill definition, downloads the client, and sets up SkillSafe automatically.

Sign In & Save

skillsafe auth
skillsafe save ./my-skill --version 1.0.0
