This MCP server has 11 tools with significant definition quality gaps. Most tools have basic descriptions but lack detailed parameter documentation and output schema specifications. Two major issues dominate: (1) Four tools (tools 1, 2, 4, 5) are explicitly marked [LEGACY] and cover only 4-8% of their respective documentation, creating poor user experience and forcing LLMs to choose between inadequate options. (2) Parameter descriptions are minimal, most parameters have 1-2 line descriptions lacking format constraints, ranges, or usage guidance. Output schemas are not documented in the visible code, making it impossible for LLMs to plan downstream tool calls or validate responses. Tool naming is mostly strong (verb_noun pattern followed), but descriptions range from 40-150 characters with several generic or incomplete. Error handling is not visible in the code provided. The server does implement input validation patterns (regex constraints on some parameters), but this alone cannot compensate for missing output documentation and the fundamental design flaw of offering deprecated legacy tools alongside newer replacements.

• Remove or deprecate tools 1, 2, 4, 5 (the [LEGACY] tools). They create decision overhead and explicitly redirect users to better tools. If you want backward compatibility, mark them as hidden/internal so LLMs don't see them in tool listings.
• Document output schemas for all tools. For each tool, specify the exact JSON/text structure returned. Example: 'Returns text field containing markdown-formatted documentation with sections and code blocks. No pagination, full docs in single response (may exceed 100KB).' This enables LLMs to parse responses correctly.
• Expand parameter descriptions to 30-50 characters minimum. Instead of 'The documentation topic (e.g., 'routing', 'hooks')', write 'Topic key from list_sveltekit_topics: alphanumeric, hyphens, underscores, dots only. Max 50 chars. Examples: routing, error-handling, server-hooks.'
• Add error handling guidance to tool descriptions. Example: 'If topic not found, returns empty result. Try list_sveltekit_topics to see available topics, then retry with exact topic name.' This teaches LLMs how to recover from common failures.
• For tools returning potentially large results (get_svelte_full_docs, get_tailwind_full_docs), add a note in the description: 'Returns complete documentation in one call. Typical response size: 50-100KB. Use search_svelte_docs for targeted queries if context is limited.'
• Document the content structure returned by list_* tools. Example: 'Returns newline-separated list of category names. Each name matches the category parameter for list_snippets_in_category calls.'
