Server has 5 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have input schemas (Zod-validated) and descriptions present, but descriptions are generic (10-80 chars, well below the 194-char baseline). Parameter descriptions are minimal or absent. No output schemas documented. Error handling is absent, tools return raw success/failure without recovery guidance. No tool annotations (readOnlyHint, idempotentHint). Tools are read-only and well-named (verb_noun pattern), but lack the depth expected for A/B grades.

• Expand tool descriptions to 100-200 chars. Include WHAT the tool does, WHEN to use it (vs similar tools), and WHAT it returns. Example: 'Fetch the 10 most recent posts from the Solana forum, ordered by creation date. Use this to discover new discussions; use GET_TOP_POSTS for trending content. Returns array of {title, author, url, category, replies_count}.'
• Document output schemas explicitly. Define the structure of the 'posts' array: [{title: string, author: string, url: string, category: string, replies_count: number, views_count: number, ...}]. This enables LLMs to plan downstream calls and extract the right fields.
• Add error handling with recovery guidance. Catch network timeouts, invalid URLs, and parsing failures. Return structured errors: {status: 'error', code: 'TIMEOUT', message: 'Forum request timed out. Retry in 5 seconds.', retryable: true}.
• Add tool annotations. Mark all tools with readOnlyHint: true and idempotentHint: true so LLMs know they are safe to retry without side effects.
• Add parameter descriptions. For SEARCH_POSTS, describe 'keyword' as 'The search term (1-100 chars). Supports partial matches and boolean operators (AND, OR, NOT).' For GET_POSTS_BY_CATEGORY, describe each enum value: 'sRFC: Solana Request for Comments, Research: peer-reviewed research, Governance: DAO governance proposals, ...'
