What is an agent skill?

An agent skill is a Markdown file of instructions that a coding agent loads when a task matches it.

Last updated November 9, 2026

The short version

An agent skill is a Markdown file of instructions that a coding agent loads when a task matches it. It tells the agent which commands exist, the right order to run them in and how to handle failures. Skills are lighter than a custom integration because any agent that reads files can use one.
