CLI tool for adding Galaxy UI components to Vue, React, Angular, Next.js, Nuxt.js, React Native, or Flutter projects
Galaxy Nebula CLI has 7 tools with basic schemas and descriptions, but significant gaps prevent production use. All tools have descriptions (10-50 chars, below the 50-200 char LLM-optimized baseline), and input schemas are present but sparse. Parameter descriptions are minimal or absent. No output schemas documented. Error handling and recovery guidance missing. Tool names lack clear verb-noun patterns (e.g., 'migrate tailwind' should be 'migrate_tailwind_project'). No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear read/write semantics. Composition is reasonable (tools are single-purpose), but descriptions do not guide LLM selection or explain when to use each tool.
Add components to your project
Diff installed components against the registry source
Diagnose your Galaxy UI setup
Initialize Galaxy UI in your project
List available Galaxy UI components
Migrate a Tailwind v3 project to the Galaxy UI v4 scaffold
Update installed components from the registry (with backup)
Tool descriptions are too short (10-50 chars) to guide LLM selection. Baseline for LLM-optimized descriptions is 50-200 chars. E.g., 'init' is 'Initialize Galaxy UI in your project' (36 chars), lacks context on when to use it vs other tools, what it modifies, or prerequisites.
No output schemas documented. LLMs cannot plan downstream calls or extract required fields. E.g., 'list' returns component names but schema does not specify structure (array of strings? objects with metadata?), pagination, or total count.
Parameter descriptions are missing or minimal. E.g., 'add' has 'components' (array) with description 'Component names to add', does not specify format, valid values, or how to discover available components. 'registryUrl' lacks explanation of integrity verification or when to use it.

No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear semantics. 'init', 'add', 'update', 'migrate tailwind' are destructive (WRITE risk) but not marked. 'list', 'doctor', 'diff' are read-only but not marked. LLMs cannot infer retry safety or side effects.
Tool name 'migrate tailwind' uses space instead of underscore and lacks clear verb-noun pattern. Should be 'migrate_tailwind_project' or 'migrate_to_galaxy_ui'. Ambiguous names reduce LLM clarity on intent.
