What problem does it solve? Adding a new rule, skill, slash command, or sub-agent to a .claude/ configuration directory is error-prone: inconsistent frontmatter, mismatched tone, and forgotten index entries make new assets invisible or incoherent. This Skill provides the conventions, templates, and wiring steps to extend the config consistently. ## Core Features & Use Cases - Four asset templates: Provides copy-ready Markdown templates for rules, skills, commands, and agents with the correct frontmatter fields for each type. - Convention enforcement: Defines tone, cross-linking, and pairing rules (e.g., a scaffolding skill gets a matching slash command and reviewer agent) so new assets match existing ones. - Mandatory index wiring: Specifies exactly how to register each new asset in CLAUDE.md and README.md so it is discoverable. - Use Case: You want to add a new /new-controller slash command. The Skill gives you the command template, tells you to pair it with the corresponding skill, and lists the exact tables in CLAUDE.md and README.md to update. ## Quick Start Ask the AI to add a new rule, skill, command, or agent to the .claude directory following the extending_claude_config conventions and to update both index files.
