Two tools with complete schemas and reasonable descriptions. searxng_web_search has good parameter coverage with enums for constrained inputs (time_range, safesearch, language). web_url_read is minimal but functional. Both descriptions exceed 20 chars and explain purpose. However, parameter descriptions are sparse (e.g., 'URL' for web_url_read is only 3 chars), output schemas are undocumented, and error handling guidance is absent. No tool annotations (readOnlyHint, idempotentHint). Naming follows verb_noun pattern correctly. Missing: output structure documentation, error recovery guidance, and richer parameter context.

• Document output schemas for both tools. E.g., searxng_web_search returns array of {title, content, url}; web_url_read returns markdown string. Include in tool description or as a separate outputSchema field.
• Expand web_url_read parameter description from 'URL' to 'The full URL to fetch and convert to markdown (e.g., https://example.com/article). Supports http and https schemes.'
• Add error recovery guidance: 'If SearXNG API returns 500, verify SEARXNG_URL environment variable is set and the instance is running. If timeout occurs, try a simpler query or increase timeout via SEARXNG_TIMEOUT env var.'
• Add tool annotations: set idempotentHint=true and readOnlyHint=true on both tools to signal they are safe to retry and do not modify state.
• Clarify language default: either set default to 'en' (explicit) or document 'Default depends on SearXNG instance configuration; omit to use instance default.'
