+title: Reusable agent skills across CLI and Registry
+sidebar_label: 'Apr 6: Agent skills'
+description:
+  ToolHive adds agent skills support across the CLI and Registry Server, letting
+  teams create, publish, and install reusable instruction bundles that teach AI
+  agents how to use MCP tools effectively.
+---
+
+ToolHive now supports agent skills - reusable bundles of instructions and
+configuration that teach AI agents how to perform specific tasks. MCP servers
+give agents the raw tools they can call; skills give them the knowledge of when,
+why, and how to use those tools effectively. With ToolHive, teams can create
+skills, publish them to a registry, and install them across supported AI clients
+from a single CLI.
+

+
+## ToolHive CLI: Install, package, and publish skills
+
+The ToolHive CLI adds full lifecycle management for agent skills, from discovery
+through distribution:
+
+- **Install skills from multiple sources** including the ToolHive Registry
+  Server, OCI registries, or Git repositories. ToolHive writes skill files to
+  your AI client's skills directory automatically, so the agent discovers them
+  without manual file management.
+- **Scope skills to users or projects** depending on whether you want a skill
+  available across all your work or limited to a specific codebase. User-scoped
+  skills install globally, while project-scoped skills activate only when
+  working in that repo.
+- **Build and publish skills** as OCI artifacts to share them with your team
+  through any container registry. The CLI handles validation, packaging, and
+  pushing using your existing registry credentials.
+
+Skills follow the
+[Agent Skills specification](https://agentskills.io/specification), an open
+standard for AI coding agents. See the
+[skills management guide](/toolhive/guides-cli/skills-management) for the full
+CLI reference and the
+[client compatibility page](/toolhive/reference/client-compatibility) for the
+current list of skill-capable clients.
+
+## Registry Server: Centralized skill discovery and versioning
+
+The [Registry Server](https://github.com/stacklok/toolhive-registry-server) adds
+an extensions API for publishing and managing skills alongside your MCP server
+registry:
+
+- **Publish versioned skills** with namespace isolation using reverse-DNS
+  notation to prevent naming collisions across teams. The registry tracks
+  multiple versions of each skill and automatically updates the latest pointer
+  as new versions are published.
+- **Search and filter skills** by keyword, status, or namespace with
+  cursor-based pagination, so teams can discover relevant skills from large
+  catalogs without scrolling through everything.
+- **Lifecycle management** lets you mark skills as active, deprecated, or
+  archived, giving platform teams clear controls over which skills are approved
+  for use across the organization.
+
+Skills are stored under a separate extensions API path and not intermixed with
+MCP server entries. See the
+[registry skills guide](/toolhive/guides-registry/skills) for the API reference
+and publishing workflow.
+
+:::note
+
+Skills management in the ToolHive Desktop UI is coming soon, bringing discovery
+and installation into the app alongside MCP server management.
