Agent Skills
Browse, discover, and invoke — 11,000+ open skills for AI agents.
Agent skills are reusable behavior packages that AI agents invoke at runtime to extend their capabilities. A skill is a SKILL.md file — structured markdown containing instructions, workflows, and domain expertise. Unlike static prompts, skills are discoverable, versioned, and composable — an agent can invoke a skill it has never seen before.

How Agent Skills Work
- 1
Agent encounters a task — Any task — writing a commit message, reviewing a PR, drafting documentation.
- 2
Agent queries the registry — Sends task context to Invoked via MCP. Receives matching skills ranked by relevance.
- 3
Skill is invoked — Agent reads the SKILL.md content and follows its instructions for the task. No human in the loop.

What are agent skills?
Agent skills are reusable behavior packages that AI agents invoke at runtime to extend their capabilities. A skill is a SKILL.md file — structured markdown containing instructions, workflows, and domain expertise that guide how an agent approaches a specific task. Unlike static prompts, skills are discoverable, versioned, and composable.
How do agent skills work?
An agent encounters a task, queries a skills registry like Invoked via MCP, receives matching skills ranked by relevance, then reads the SKILL.md content and follows its instructions for that task. No human installation step is required — discovery happens at runtime.
Where can I find agent skills?
The Invoked registry at invoked.sh indexes 11,000+ community agent skills. Connect your agent once via MCP and it queries the registry automatically at runtime.
What is the difference between agent skills and MCP tools?
MCP tools give agents new capabilities — functions they can call, APIs they can access. Agent skills give agents new knowledge — instructions and workflows that guide how they approach a task. The Invoked registry is an MCP server, but it delivers skills (instructional content) rather than tools (callable functions).
How do I publish an agent skill?
Add a SKILL.md file to any public GitHub repository and claim it on Invoked at invoked.sh/register. Your skill becomes immediately discoverable by agents querying the registry — no approval process required.
What is a SKILL.md file?
A SKILL.md file is a structured markdown file that defines an agent skill — its name, description, and the instructions an AI agent should follow when the skill is invoked. It is the standard format for skills registered in Invoked.
