793With `context: fork`, you write the task in your skill and pick an agent type to execute it. The built-in Explore and Plan agents [skip CLAUDE.md and git status](/docs/en/sub-agents#what-loads-at-startup) to keep their context small, so a forked skill using `agent: Explore` sees only the SKILL.md content and the agent's own system prompt. For the inverse, where you define a custom subagent that uses skills as reference material, see [Subagents](/docs/en/sub-agents#preload-skills-into-subagents).

The built-in Explore and Plan agents [start without CLAUDE.md and git status](/docs/en/sub-agents#what-loads-at-startup) to keep their context small. Put everything the task needs in your SKILL.md. A forked skill using `agent: Explore` starts with that content and the agent's own system prompt, and none of your CLAUDE.md files.
