18 tools with explicit schemas and descriptions, but critical gaps undermine quality. All tools have descriptions (10-50 chars, mostly generic), and input schemas are present but severely underdeveloped. Parameter descriptions are minimal or absent (e.g., 'RFCDocument' with no explanation of structure). No output schemas documented. No error handling guidance. No tool annotations (readOnlyHint/destructiveHint). Naming is verb-forward (get_, set_, add_, update_) but many tools are granular getters (get_title, get_abstract, get_copyright) that could be consolidated. The 'document' parameter appears in 14 tools but is never explained, LLMs cannot infer it's a complex object. No pagination, no result limits, no chaining IDs. Security: no secrets exposed, but no permission gates or audit trails. Composition: heavy reliance on passing RFCDocument objects between tools creates tight coupling and requires LLMs to manage state manually.

• Document the RFCDocument object schema explicitly. Show required fields (rfc_number, title, sections, etc.), types, and constraints. Either inline in parameter descriptions or as a shared definition.
• Consolidate 8 getter tools (get_title, get_abstract, get_copyright, get_status_of_memo, get_toc, get_acknowledgements, get_contributors, get_authors_address) into a single 'get_rfc_metadata' tool that returns all metadata fields at once. Reduces call count and token waste.
• Add output schemas to all tools. For load_rfc and download_rfc, document the RFCDocument structure returned. For getters, document the exact field type (string, array, object). For save_rfc, document success/failure response.
• Add error handling guidance: 'If file not found, check the filepath. If parse fails, ensure the file is a valid RFC TXT format.' Include recovery hints for network errors (retry with exponential backoff).
• Add tool annotations: mark get_* tools with readOnlyHint=true; mark save_rfc, create_rfc, set_*, add_*, update_* with destructiveHint=true; mark idempotent operations (e.g., set_title with same value) with idempotentHint=true.
