Chainguard Agent Skills overview

Fri, 05 Jun 2026 08:48:45 +0000

Chainguard Agent Skills is a catalog of hardened AI agent skills that Chainguard reviews, scopes, and publishes with a full audit trail. It lets teams extend their AI agents without extending their attack surface.

Note: Chainguard Agent Skills is in beta. Available to Chainguard Containers customers who sign up for the beta program. You can sign up by visiting the Chainguard Agent Skills product page and clicking Join the beta.

What is an agent skill?

An agent skill is a small, modular instruction set — typically a single SKILL.md file — that extends what an AI agent can do. Agents such as Claude Code use skills to perform tasks like browser automation, database management, and code generation.

Getting started with the Chainguard Skills Registry

Fri, 05 Jun 2026 08:48:45 +0000

The Chainguard Skills Registry lets you publish, manage, and distribute skills scoped to your organization. Use chainctl to upload original skills to uploads.cgr.dev, submit them for hardening, and install the hardened results from skills.cgr.dev.

This guide walks through enabling the registry for your organization, then uploading, hardening, installing, and running a skill. For job tracking, digest-based submissions, and browsing user folders, see Getting started with skill hardening.

Note: Chainguard Skills Registry is in beta.

Getting started with the Chainguard Agent Skills public registry

Mon, 08 Jun 2026 08:48:45 +0000

Chainguard publishes a curated set of hardened agent skills in a public registry at skills.cgr.dev/public. Anyone with chainctl can browse and install them — no entitlement and no legal terms required. The Chainguard Agent Skills public registry is pull-only: you can install skills from the registry, but you can’t push your own skills to it.

This guide walks through the full workflow: listing the available skills, inspecting one, pulling it to audit how Chainguard hardened it, installing it, and running it with an agent.

Using the Chainguard Agent Skills Public Skills MCP server

Tue, 04 Aug 2026 00:00:00 +0000

Chainguard serves its curated set of hardened agent skills to agents directly over the Model Context Protocol (MCP) through the Public Skills MCP server. Where the public registry is the chainctl way of browsing and installing public skills onto your machine, the Public Skills MCP server is the way an agent discovers and loads those same skills live — searching the catalog, inspecting a skill, and loading one in full to run, without a separate install step.

Getting started with skill hardening

Tue, 22 Sep 2026 00:00:00 +0000

Use chainctl skills harden to upload an agent skill, submit it for server-side hardening, and download the result with a report of the changes and scanner findings. You can submit a local directory or harden an artifact you have already pushed to your organization’s uploads registry.

This guide builds on Getting started with the Chainguard Skills Registry, covering hardening and job tracking before you install the skill.
