What is the difference between a Claude Command and a Skill?

Commands are single-file workflows (.md) intended for simple tasks like /commit, while Skills are multi-file directories containing a SKILL.md and supporting assets for complex workflows.

What are the requirements for a valid SKILL.md file?

A valid SKILL.md requires a YAML frontmatter section with name and description fields, followed by a markdown body using standard headings like 'What It Does' and 'Usage'.

What does 'context: fork' do in a Claude skill?

Setting 'context: fork' creates an isolated subagent context with its own tool access rules, preventing the subagent from seeing the parent conversation for more focused tasks.

How should I handle large documentation within a skill?

Apply the 'Progressive Disclosure' pattern by keeping the main SKILL.md under 500 lines and moving detailed API refs or examples into separate markdown files within the same directory.

How do I inject shell command output into a skill?

You can use backticks with a '!' prefix (e.g., `!git branch`) to inject shell output directly into the skill prompt during execution.
