The Bitrise MCP server provides 5 well-structured tools with generally solid naming conventions (all verb-noun style) and comprehensive input schemas. Tool descriptions are present and informative, ranging from ~90-210 characters. Parameter schemas are detailed with type information, enums, and descriptions. However, there are critical gaps: (1) Output schemas are not documented for any tool, the rubric requires 'Document the output schema' for tools to receive full credit; (2) Error handling guidance is absent, no recovery hints, categorization, or actionable error messages; (3) Some parameter descriptions are generic or lack constraint details (e.g., 'id' in create_connected_app just says 'uuidV4' without saying it's auto-generated if omitted); (4) The 'delete_app' description lacks severity warning and doesn't mention dry-run/confirmation patterns for an irreversible operation. The server demonstrates good fundamentals but falls short of production-grade tool design on critical dimensions.

• Add explicit output schemas for all 5 tools in tool definitions or documentation. Example for get_connected_app: 'Returns: { id: string, platform: string, store_app_id: string, workspace_slug: string, project_id?: string, created_at: ISO8601, ... }'
• Enhance delete_app description to include severity warnings and consequences: 'DESTRUCTIVE: Permanently deletes the app and all associated data. Cannot be undone. Affected workspaces will lose access. Consider creating a backup before deletion.'
• Add error categorization documentation. For example, document that 'invalid platform' is user-fixable (suggest valid enum values), 'workspace not found' is retryable with discovery (suggest search_workspace), and 'permission denied' is fatal (user needs elevated access).
• For create_connected_app, clarify parameter relationships in descriptions: 'If manual_connection=true, store_app_name and store_credential_id are required. If manual_connection=false, store_credential_id must be provided; store_app_name is ignored.'
• Add dry-run or confirmation support to delete_app. Modify schema to accept optional 'dry_run: boolean' parameter. When true, return what would be deleted without executing. This prevents catastrophic accidental deletions.
• Document list_connected_apps pagination metadata in response: include 'total_count: number' and clarify how page/items_per_page interact. Example: 'With items_per_page=10 and total_count=25, pages are [1..3]. Requesting page=3 returns items 21 - 25.'
• Simplify or add examples for complex nested params. For tester_groups in create_connected_app, provide a concrete example: { name: 'beta_testers', type: 'internal', auto_notify: true, user_slugs: ['user1', 'user2'] }
