check_nsec_walkability

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, so the description adds limited behavioral context. It does specify the tool analyzes configuration and detects issues, but does not disclose additional traits like rate limits, data caching behavior beyond force_refresh, or how results are returned. No contradiction with annotations.

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 extremely concise with two short sentences. It front-loads the core purpose immediately and includes no extraneous information.

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 that an output schema exists (not shown) and annotations are rich, the description provides reasonable completeness. It explains the purpose and what the tool detects. However, it could mention that the domain must be DNSSEC-signed for this analysis to be meaningful, and it lacks a brief note on output interpretation (e.g., 'returns a risk score').

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%, so the schema already explains all three parameters adequately. The description does not add any additional meaning or context for parameters beyond what is in the schema.

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 tool assesses zone walkability risk by analyzing NSEC3PARAM configuration, with specific detection of plain NSEC zones, weak NSEC3 parameters, and opt-out flags. It uses a specific verb and resource, distinguishing it from sibling tools like check_dnssec or check_dnskey_strength.

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 alternatives. It does not mention prerequisites (e.g., DNSSEC must be enabled) or when the tool is not appropriate. No explicit when-to-use or when-not-to-use context is given.

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