debug_dns_config

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

No annotations are provided, so the description carries the full behavioral burden. 'Debug' and 'checks' imply a read-only diagnostic operation, and the enumerated checks give real scope information, but the text says nothing about permissions required, whether the checks are safe to run in production, what happens when pod_name is omitted, or what the result looks like.

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?

A single front-loaded sentence with no filler, and the three checks are listed compactly. It is efficient but so compressed that no guidance or behavior could be included.

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?

With no annotations and no output schema, the description must carry the definition, and it covers the scope of checks but not the return shape, permissions, or the difference between the optional pod-level path and the cluster-level CoreDNS path. Adequate but with clear gaps for a two-mode 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 description coverage is 100% for both optional parameters, so the schema already explains pod_name and namespace including the default. The description adds no additional semantics, such as what the pod_name check reports beyond policy, so the baseline of 3 applies.

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?

The description pairs a specific verb ('Debug') with a resource ('DNS') and enumerates the three concrete checks: CoreDNS health, Corefile config, and pod DNS policy. However, it does not differentiate itself from the sibling coredns_health_check, which appears to cover an overlapping portion of the same scope.

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?

There is no statement of when to use this tool versus coredns_health_check, check_service_endpoints, or trace_service_to_pods, nor any exclusion or prerequisite. The only usage hint is what the name implies.

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