Critical failures across all dimensions. Of 39 tools, 35 have ZERO visible input schemas (tools 5-39 show 'Input: {}' with no properties). Only 4 tools (get_me, enable_toolset, list_available_toolsets, get_toolset_tools) have documented schemas. Descriptions vary wildly: get_me has 95 chars (good), but 35 tools lack descriptions entirely or are inferred from names only. No output schemas documented. No error handling guidance. Tool composition is reasonable (verb_noun naming), but schema and description deficits are disqualifying.

• Add complete input schemas to all 35 tools lacking them. Each schema must include 'type', 'properties', 'required', and per-parameter 'description'. Example: search_repositories should document owner, repo, query, limit, offset parameters with types and constraints.
• Write descriptions for all 35 tools. Follow the 50-200 char baseline. Format: 'ACTION what it does. WHEN to use it. RETURNS what fields.' Example: 'Search GitHub repositories by name, language, or stars. Use when user asks to find a project. Returns repo name, URL, stars, language.'
• Document output schemas for all tools. Specify which fields are returned, their types, and which are required for chaining. Example: search_repositories should document that it returns [{ name, url, stars, language, owner_login }] so downstream tools know what to expect.
• Add error handling guidance to tool descriptions. State common failure modes and recovery steps. Example: 'If repository not found, try search_repositories() with a partial name. If rate-limited, wait 60 seconds and retry.'
• Add destructiveHint and idempotentHint annotations to write tools. Mark create_repository, merge_pull_request, etc. with destructiveHint=true so agents know these are irreversible. Mark idempotent operations so agents can safely retry.
