check_cluster_health

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the burden. It explains parameter behavior (defaults, conditional applicability) and indicates the return type, but does not explicitly state whether the operation is read-only, requires specific permissions, or what constitutes a health check.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with purpose, Args, and Returns sections, each concise. The docstring format is slightly verbose but every sentence provides necessary detail without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers the essential context: purpose, parameters, and return value. With no annotations or output schema, it could be more detailed about the result structure and potential side effects, but is adequate for a health-check tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, but the description compensates fully by explaining each parameter's purpose, default, and inter-dependencies (e.g., rbac_namespace only when include_rbac_check is True, kubeconfig_path vs cluster_name precedence).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states a specific action: check Kubernetes cluster health, optionally with RBAC conflict detection. This distinguishes it from sibling tools like check_node_health and check_pod_health by focusing on cluster-level and the unique RBAC feature.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the purpose (check health), but no explicit guidance on when to use this over sibling health tools like check_node_health or check_pod_health, nor any exclusions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
