Critical gaps across all dimensions. Tool names use placeholder {provider}_ prefix, making them non-functional and unparseable by LLMs. Descriptions are minimal (10-30 chars) and lack context on WHEN to use each tool or what they return. Input schemas present but sparse, most parameters lack descriptions entirely. No output schemas documented. No error handling guidance. No parameter constraints (enums, ranges). Tool composition is poor: create_instance requires 'location' as optional but no guidance on valid values or format. No idempotency markers. Security: credentials injected via environment but no audit trail or permission gates visible. Overall, this reads as an early prototype rather than production-ready tooling.

• Replace {provider}_ placeholder naming with concrete provider names (aws_list_instances, azure_list_instances, gcp_list_instances) or use a single canonical tool name (list_compute_instances) with a 'provider' parameter. Current pattern breaks LLM parsing.
• Expand all descriptions to 50 - 150 characters. Include WHAT (action), WHEN (use case), and WHAT IT RETURNS. Example: 'List all compute instances in the selected region. Returns instance ID, name, state, and IP address. Call this first to discover available resources before starting/stopping.'
• Add descriptions to every parameter. For 'size', specify format: 'Instance size/flavor (e.g., t2.micro, t2.small, t3.medium for AWS; Standard_B1s, Standard_B2s for Azure). See provider docs for valid options.' For 'location', add: 'Cloud region (e.g., us-east-1, us-west-2 for AWS; eastus, westus for Azure). Defaults to provider default if omitted.'
• Document output schemas for all tools. Example for list_instances: 'Returns array of {id: string, name: string, state: string (running|stopped|terminated), ip_address: string, region: string}.' This enables LLMs to extract and chain results.
• Add confirmation step for destructive tools. Implement a dry-run parameter or a separate 'confirm_delete_instance' tool that requires explicit confirmation before deletion. Include recovery guidance: 'Deletion is permanent. To undo, restore from backup or recreate the instance.'
