Single tool 'statepulse_live_telemetry' has critical definition gaps. Description is 169 chars but lacks actionable context (WHAT does it do? WHEN to call it? WHAT does it return?). Input schema is empty object with no parameters documented. No output schema defined. Description mentions a remote endpoint and pricing but provides no guidance on tool behavior, return structure, or error handling. Tool name lacks action verb (should be 'get_telemetry' or 'fetch_live_telemetry'). No parameter descriptions exist because schema is empty. Fails baseline: 100% of A+ tools have documented return types; 94% have docstrings; 100% of A+ tool params have descriptions.

• Rename tool to 'get_live_telemetry' or 'fetch_environmental_metrics' to start with an action verb. This helps LLMs infer intent from the name alone.
• Define input schema with at least one parameter (e.g., 'metric_type' enum: [temperature, humidity, air_quality, ...] or 'location_id' string). Empty schema suggests the tool does nothing.
• Document output schema explicitly. Describe the structure of returned telemetry data: field names, types, units, and which fields are always present vs optional.
• Expand description to 100-200 chars explaining: (1) What telemetry data this retrieves, (2) When to call it (e.g., 'Use this to fetch real-time environmental metrics'), (3) What the response contains (e.g., 'Returns temperature, humidity, air quality index, and timestamp').
• Add error handling guidance: 'If the API is unavailable, retry after 30 seconds. If rate-limited (402 USDC insufficient), inform the user of the cost and ask for confirmation.'
