CocoaSkills
An enterprise-grade package manager and security PKI for AI agent skills.
What it is
CocoaSkills is a dependency manager for AI agent skills — the reusable instruction packages that give coding agents specialized capabilities. It brings to a young, fast-moving ecosystem the tooling that mature package managers (Bundler, SPM, Cargo, Gradle) take for granted: declarative manifests, reproducible installs, and version pinning.
Why it matters
Skills are a new embodiment of source code. Even a plain-markdown skill can carry a prompt-injection payload, and as skills grow they pull in binaries that demand real supply-chain security. Content scanning alone cannot catch publisher impersonation, artifact tampering, silent mutation inside a pinned version, or post-install substitution — those require public-key cryptography. CocoaSkills closes that gap with an SSH-certificate signing model, hierarchical CA trust, and pluggable identity verification: a PKI purpose-built for agent-skill artifacts, working across both public and self-hosted registries.
Who it is for
Teams that run agents in production and need their skill supply chain to be reproducible, attestable, and auditable — the same rigor they already apply to code dependencies.
