Server has 8 tools with complete JSON Schema definitions and descriptions. Naming follows verb_noun convention (list_, get_, create_). However, parameter descriptions are sparse or missing for many fields. Output schemas are not documented. Error handling lacks recovery guidance. Tool descriptions are adequate (100-150 chars) but lack context on when to use each tool vs. alternatives. No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels. Missing idempotency guidance for write operations.

• Add output schema documentation to all 8 tools. Specify return type (object/array), required fields, and field types. Example: create_issue returns {issue_id: string, issue_url: string, created_at: string}.
• Add tool annotations via MCP spec. Mark create_issue and create_pull_request with destructiveHint=true. Mark all read-only tools with readOnlyHint=true. Mark idempotent operations with idempotentHint=true.
• Enhance error messages with recovery guidance. Instead of 'Error handling tool create_issue: [error]', return structured errors like {error: 'Repository not found', suggestion: 'Call list_repositories() to find valid owner/repo combinations'}.
• Add limit and offset parameters to list_repositories, list_issues, list_pull_requests. Document default limit (e.g., 20) and max limit (e.g., 100). Return total_count in response.
• Expand parameter descriptions. For 'owner', add '(GitHub username or organization name)'. For 'ref', add '(branch name, tag, or commit SHA; defaults to default branch)'.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
