Single tool 'getAccessScope' has critical definition gaps. No input parameters documented despite accepting none (empty required array suggests intentional zero-param design, but no description explains this). Tool description is present (67 chars) but lacks context on WHEN to call it, WHAT it returns, or WHY an agent would use it. No output schema visible in source. Tool name lacks action verb prefix ('get_' is present but 'getAccessScope' uses camelCase instead of snake_case convention). No parameter descriptions exist (N/A since no params, but this is unusual for a tool that queries permissions). Error handling and recovery guidance absent. Overall: minimal viable definition, far below production baseline of 194 chars avg description and 100% param documentation.

• Rename 'getAccessScope' to 'get_access_scope' (snake_case) to match Arcade naming convention and improve LLM parsing.
• Expand tool description to 100-150 chars: 'Queries the access scope of an API key to determine what permissions and projects are available. Call this first to verify the key has required permissions before attempting tracking operations. Returns: permissions array, project list, and role information.'
• Document output schema explicitly: { permissions: string[], projects: { id, name, role }[], expiresAt: ISO8601 }
• Add error handling guidance: 'If key is invalid, returns 401 Unauthorized. If expired, returns 403 Forbidden with expiration date. Suggest user regenerate key in Trackdolphin dashboard.'
• Expand tool set to cover core domain: add send_conversion_event, query_conversion_results, list_projects, create_pixel, update_pixel_config tools to match stated 'server-side conversion tracking' purpose.
