Critical gaps across all dimensions. Of 39 tools, 9 lack descriptions entirely (PostDmTool, PostMessageTool, PostWebhookTool, SearchModelsTool, GetModelInfoTool, GetModelSampleImagesTool, GetReadmeTool, WhoamiTool across multiple servers). Input schemas are visible for only ~15 tools; the remaining 24 tools have no visible schema definitions in the provided source. Parameter descriptions are sparse or missing. No output schemas documented. Error handling is absent from visible code. Tool names lack consistent verb-noun structure (e.g., 'PostDmTool' vs 'PostDm'). No evidence of idempotency, rate limiting, or secret injection patterns. The codebase registers tools but does not expose their full definitions in the provided excerpts, making comprehensive evaluation impossible.

• Add non-empty descriptions to all 24 undocumented tools. Each description should be 50 - 200 characters, stating WHAT the tool does, WHEN to use it, and any prerequisites. Example: 'Create a new product in Shopify with name, description, and price. Returns product_id for use in add_product_image.'
• Document input schemas for all tools. For each parameter, specify type (string, integer, enum), description (20+ chars), and constraints (min/max, regex, allowed values). Use JSON Schema format with explicit type definitions.
• Document output schemas. For each tool, list the fields returned, their types, and descriptions. Include IDs and references needed for downstream tool calls (e.g., if create_product returns product_id, ensure update_product accepts product_id).
• Add error handling guidance. For each tool, document: (1) what errors can occur, (2) whether they are retryable, (3) what the LLM should do next. Example: 'If user not found, call search_users() with a partial name.'
• Implement confirmation patterns for destructive tools (delete_*). Add a dry_run parameter or a separate confirm_delete tool. Gate deletions behind permission checks and log all destructive operations for audit trails.
