This server exhibits severe deficiencies across all definition quality dimensions. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a trivial tool description. The source code provided shows only a stub MCP server that prints a JSON status message and references an external client class without exposing the actual tool implementation. No tool registration, parameter validation, error handling, or output schema documentation is visible. The code does not implement the MCP protocol spec, it merely outputs a static JSON string to stdout and exits, which is non-functional as an MCP server.

• Define the tool in mcp_server.py with explicit tool registration including name, description (10-1024 chars), inputSchema with parameter types and descriptions, and outputSchema documenting return fields.
• Rename the tool to reflect its domain and action more clearly. Consider 'calculate_backoff_delay' or 'get_retry_delay', these names convey that the tool computes exponential backoff timing for rate limit recovery.
• Add comprehensive parameter documentation. If the tool accepts 'attempt' (as suggested by client.py), describe it: 'The attempt number (integer, 1-based). Used to calculate exponential backoff delay. Max 10 to prevent overflow.'
• Define the output schema. E.g., { 'delay_seconds': { 'type': 'number', 'description': 'The number of seconds to wait before retrying. Calculated as 2^attempt.' }, 'next_attempt': { 'type': 'integer', 'description': 'The suggested next attempt number.' } }
• Add error handling: 'If attempt exceeds 10, return error "Backoff attempt too high. Max 10 attempts. Consider circuit breaker pattern instead." This guides the LLM to use a different strategy rather than retry indefinitely.
• Document any constraints: e.g., maximum backoff cap (e.g., 'Delay is capped at 3600 seconds (1 hour) to prevent indefinite waits'), jitter options if applicable, and when this tool should be used (e.g., 'Call this after receiving HTTP 429 or similar rate limit response').
