search_dns_host_overrides

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

Annotations already declare the read-only and non-destructive nature. The description adds only that filtering and pagination are supported, which is also evident from the schema parameters. No further behavioral traits are disclosed, but the annotations carry the safety burden, so this is adequate.

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?

The description is a single, front-loaded sentence that efficiently conveys the core purpose. Every word earns its place with no redundancy or fluff.

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?

Given the full schema, output schema, and annotations, the description is minimally adequate. However, it lacks any context about how this tool differs from very similar siblings like 'search_dns_forwarder_host_overrides', which would be valuable for an agent navigating a large toolset.

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?

The schema description coverage is 100%, with each of the 6 parameters already documented in detail. The description itself adds no parameter-specific semantics beyond the schema's existing information, 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 clearly states the verb 'search' and the resource 'DNS host overrides', with an additional scope of 'filtering and pagination'. It does not explicitly differentiate from similar sibling tools like 'search_dns_forwarder_host_overrides', but the resource name is specific enough to distinguish in most contexts.

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?

The description provides no guidance on when to use this tool versus similar search tools, nor any exclusions or alternatives. The generic phrase 'with filtering and pagination' does not help an agent choose between this and related DNS search tools.

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