Skills & Subagents Frontmatter
Skills gained context: fork, paths:, and effort: options. Subagents gained isolation: worktree and memory: project/user/local for persistent knowledge.
"Customize Claude Code" Card
One of the most useful sections: a complete guide showing how to create every type of extension — slash commands, skills, subagents, rules, hooks, and MCP servers — each with a full frontmatter example and a decision guide for "where should this go?"
If you spot an error or a missing feature, feel free to reach out — I'll keep this cheatsheet updated as Claude Code evolves.
