Server has 6 tools with consistent naming, good descriptions, and complete input schemas. Tool names follow verb_noun convention (get_, resolve_). Descriptions average ~90 characters and clearly state what each tool does. All parameters have type definitions and descriptions. However, output schemas are not documented in the source code provided, and error handling guidance is minimal. Security posture is good (read-only tools, proper parameter typing), but the server lacks response field documentation and pagination guidance for list-like tools. Prompts feature is implemented with a detailed template. Overall quality is fair-to-good (C+/B- range) with clear room for improvement in output documentation and error recovery patterns.

• Document the output schema for each tool in code comments or jsdoc. Example: 'Returns {reviews: Array<{id, summary, status, actionable_comments}>}' so LLMs know what fields to expect.
• Add limit and offset parameters to get_coderabbit_reviews and get_review_comments with bounds (limit: 1-50, default 20). State in descriptions: 'Returns paginated results; use offset/limit to fetch large review sets without exhausting context.'
• Define error cases in tool descriptions. Example for get_coderabbit_reviews: 'Errors: If PR not found, suggests checking owner/repo/pullNumber. If rate-limited, retry after 60s.'
• Add destructiveHint and idempotentHint to resolve_comment and resolve_conversation in server.ts tool registration. Mark resolve_* as destructive=true so agents know these calls have side effects.
• Change pullNumber and reviewId parameter types from 'number' to 'integer' in JSON Schema for correctness.
• Add a tool annotation to get_comment_details clarifying it is read-only (readOnlyHint: true).
• Include in get_review_comments description: 'If results are large, use get_comment_details(commentId) to fetch individual comments by ID instead.' This guides agents away from context-heavy list calls.
• In resolve_comment and resolve_conversation, add examples of valid enum values in parameter descriptions to reduce hallucinated input.
• Validate that GITHUB_PAT environment variable exists at startup and log clearly if missing; return a structured error message if auth fails, not a raw exception.
