CRITICAL: No tool definitions are visible in the source code. The validation script (scripts/validate_public_repo.py) only lists expected tool names in a set (EXPECTED_TOOLS) and validates that TOOLS.md documents them. The actual tool schemas, descriptions, input parameters, and output structures are NOT present in the provided source. The server is HTTP-based and points to https://mcp.grabbitapp.com/api/mcp, but the implementation details are hosted remotely and not inspectable. Per HARD SCORING RULES: 'If you cannot see the actual tool definition in the source (only inferred): cap that tool's overall at 50.' Since NO tool definitions are visible, only names are listed, all tools score 0 on schema and description. The validation script proves the server exists and exposes 23 tools, but provides zero evidence of definition quality.

• Publish tool definitions (schemas, descriptions, parameters) in the repository or in server.json. Remote-only definitions cannot be audited or version-controlled.
• Add comprehensive parameter descriptions for all tools, including type, format, constraints, and examples. Follow pattern:tool-description baseline of 50-200 chars per param.
• Document output schemas for all tools. Include field names, types, and which fields are required for chaining to downstream tools.
• Implement confirmation/dry-run for destructive operations (delete_item, delete_collection). Add idempotentHint and destructiveHint annotations per current MCP spec.
• Add error handling guidance: categorize errors as retryable/user-fixable/fatal, include invalid values and constraints in error messages, and suggest recovery steps.
