32 tools with consistent naming (verb_noun pattern: get_, list_, create_, update_, delete_) and complete input schemas. All parameters have type definitions and descriptions. However, tool descriptions are uniformly terse (15-45 chars), falling below the 50-200 char baseline for LLM-optimized descriptions. No output schemas documented. Error handling and recovery guidance absent. Missing tool annotations (readOnlyHint, destructiveHint). Risk categorization present in metadata but not surfaced in descriptions.

• Expand tool descriptions to 80-150 chars. Include WHEN to use (e.g., 'Call this to fetch a single repo by owner/name; use list_user_repos to discover repos'), WHAT it returns (key fields), and any prerequisites (e.g., 'Requires repo push access').
• Document output schemas for all 32 tools. Specify which fields are returned, their types, and which are safe to pass to downstream tools. Example: 'Returns {id, name, owner, url, is_private, created_at}' so agents know repo_id is available for chaining.
• Add tool annotations: mark read-only tools with readOnlyHint=true, destructive tools (delete_*) with destructiveHint=true, and idempotent tools (get_*, list_*) with idempotentHint=true. This enables agent safety frameworks.
• Add error handling guidance to descriptions. Example: 'If repo not found, returns 404. Try list_user_repos to verify the repo exists. If permission denied, check that your PAT has repo scope.'
• Convert free-form state parameters to enums in JSON Schema. For list_issues, list_pulls, list_milestones: define state as enum ['open', 'closed', 'all'] instead of a string. Add min/max constraints to pagination (page >= 1, per_page 1-100).
