GitHub MCP has 13 tools with basic schemas and descriptions, but significant quality gaps. All tools have Zod schemas with type definitions and descriptions present, meeting minimum viability. However, descriptions are often generic (10-50 chars), parameter descriptions lack actionable constraints, and output schemas are undocumented. No error handling guidance, no pagination support for list operations, and destructive operations (delete-a-repo) lack confirmation patterns. Tool naming is reasonable (verb-noun style) but some names are ambiguous ('update-repo' vs 'update-user-profile'). The server follows a consistent pattern but lacks production-grade polish expected for A/B tier.

• Add output schema documentation to every tool. Define return type as JSON Schema with field names, types, and descriptions. E.g., get-repo-details should document: {name: string, owner: string, stars: number, url: string, ...}.
• Implement confirmation pattern for destructive tools. Wrap delete-a-repo and update-repo with a dry-run mode or require explicit confirmation parameter (confirm: true) to prevent accidental data loss.
• Add pagination to list operations. Introduce limit (default 20, max 100) and offset/cursor parameters. Return total_count and next_cursor in responses to enable multi-page iteration.
• Expand descriptions to 100-200 chars with actionable context. E.g., 'List all repositories for the authenticated user. Returns name, URL, and star count. Use this to discover repos before forking or starring.' instead of current 48 chars.
• Add error handling with recovery hints. Catch API errors and return structured responses like {error: 'User not found', suggestion: 'Try search_users() with partial name'} instead of letting exceptions propagate.
