Single tool 'incidents' has critical definition gaps. Tool name lacks action verb (should be 'get_incidents' or 'list_incidents'). Description is adequate (67 chars) but parameters lack descriptions entirely, 'component' and 'time' have no guidance on format, constraints, or usage. Input schema present but incomplete: no type declarations visible in registration, parameters lack descriptions required by pattern:tool-description. No output schema documented. Error handling returns raw errors without recovery guidance. Tool does not follow verb_noun naming convention (baseline: 90% of A+ tools start with action verb).

• Rename tool from 'incidents' to 'get_incidents' or 'list_incidents' to signal read action and match verb_noun baseline (90% of A+ tools).
• Add parameter descriptions: 'component' → 'Optional component name to filter incidents (e.g., monitoring, networking)'; 'time' → 'Optional duration string for time range query (format: 1h, 24h, 7d; default: 24h)'.
• Document output schema: describe fields returned from Prometheus (e.g., component name, incident count, severity, timestamp) so LLM can extract and chain data.
• Wrap error handling with recovery guidance: 'Invalid duration format. Use Go duration syntax: 1h, 24h, 7d. Or call list_incidents without time parameter for default 24h range.'
• Add enum or pattern constraint for 'time' parameter to prevent hallucinated formats. Validate input early and return clear error messages.
