This server has significant definition quality gaps. While tool names follow verb_noun conventions (k8s_get_pod_logs, prometheus_query, alertmanager_silence), parameter descriptions are sparse or missing entirely. The k8s_get_pod_logs tool has basic parameter descriptions but lacks output schema documentation. Prometheus tools (prometheus_health, prometheus_cpu, prometheus_memory) lack any input parameter descriptions despite accepting parameters. Critical issue: alertmanager_silence accepts a 'duration' parameter described as 'Duration like "2h", "30m"' (an example in description, which violates rubric guidance) with no format constraint or validation documented. Output schemas are completely undocumented across all 9 tools, LLMs cannot predict return structure. Error handling is generic ('Error getting logs: {e}', 'Kubernetes API error') with no recovery guidance. The server implements 2 resources (k8s://pods, k8s://pods/all, k8s://deployments, etc.) and 2 tool groups (K8s and Prometheus/Alertmanager), but tools and resources are not cross-referenced with consistent naming patterns.

• Document the output schema for each tool, including field names, types, and what data is returned. E.g. k8s_get_pod_logs returns {logs: string, pod_name: string, namespace: string, tail: integer}.
• Add explicit input schema declarations for prometheus_health, prometheus_cpu, prometheus_memory, prometheus_services. If they accept no parameters, document {} with an empty object schema.
• Replace example values in alertmanager_silence description with a format constraint: 'duration: string matching pattern ^\d+(s|m|h|d)$ (e.g., 2h, 30m, 5d)'.
• Enhance error messages with actionable recovery guidance. Instead of 'Error getting logs: {e}', return 'Pod not found in namespace. Try list_pods(namespace) to find available pods.' or 'API rate limit exceeded. Retry in 60 seconds.'
• Add idempotentHint and destructiveHint annotations to tools. Mark alertmanager_silence with destructiveHint=true; mark read-only tools with idempotentHint=true.
• Document tool chaining: 'k8s_describe_pod returns pod metadata; use pod_name from result as input to k8s_get_pod_logs.'
• Add pagination support: alertmanager_get_alerts should accept limit (1-100, default 20) and offset parameters, and return total_count in response.
• Validate input on the server side. For alertmanager_silence, check that duration matches the format constraint and reject invalid formats immediately with clear feedback.
