Critical gaps across all dimensions. Tool definitions lack visible input schemas in the provided source code, cannot verify parameter types, descriptions, or constraints. No tool descriptions are visible in the sample code provided. The 7 tools appear to be registered in separate files (activities.ts, health.ts, training.ts) but the actual schema definitions are not shown. Without access to the complete tool registration code, per-tool scoring is severely constrained. Naming follows verb_noun convention (get_*, export_*) which is positive, but this alone cannot compensate for missing schemas and descriptions.

• Provide complete tool registration code showing input schemas with parameter types, descriptions, and constraints (enums, min/max, patterns) for all 7 tools.
• Add 50-200 character descriptions to each tool explaining WHAT it does, WHEN to use it, and any prerequisites (e.g., 'Retrieve a list of recent activities from Garmin Connect. Call this first to discover available activities before fetching details.').
• Document output schemas for each tool, including field names, types, and which fields are needed for chaining to other tools (e.g., activity_id for get_activity_details).
• Add parameter descriptions for all inputs, specifying format, range, and allowed values. E.g., 'activity_id (string): The unique Garmin activity identifier returned by get_activities.'
• Implement error handling that guides LLM recovery: 'Activity not found. Call get_activities() to list available activities.' instead of bare error codes.
