Guide for creating Kit extensions. Use when the user asks to build, create, or modify a Kit extension, add a custom tool, slash command, widget, keyboard shortcut, editor interceptor, tool renderer, or hook into any Kit lifecycle event.

Guide for building Go applications with the Kit SDK. Use when the user asks to create a program, service, script, or application that uses Kit programmatically as a Go library — e.g. embedding LLM interactions, building agents, creating CLI tools powered by Kit, or integrating Kit into backend services. Do NOT use for Kit extensions (use kit-extensions skill instead).
