claude-extension-builder

Create Claude extensions using this builder, which guides you through scaffolding Skills, Slash Commands, Agents, and Hooks. It reads builder definitions, walks you through the process conversationally, and saves files to the correct global, project, or user scope location.

Run the extension builder to execute scaffolding directly from prescribed builder definitions. The Skill handles file placement, contextual guidance, and saves changes ready for commit, eliminating manual setup and integration errors.

You can both create and update existing Claude extensions. The builder reads your current definitions, guides modifications conversationally, and saves updated files to the correct scope—global, project, or user—for seamless integration.

The builder saves extensions to the correct location based on scope: global paths via Chezmoi, project-local directories, or user configuration folders. File placement is handled automatically based on the extension type and your environment.

No. The builder guides you through the process interactively and references linked builder definitions for each extension type. Contextual prompts walk you through structure and requirements without requiring prior knowledge of extension schemas.
