set_dnssec_nsec3

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

With no annotations provided, the description carries the burden. It adds a behavioral consequence ('prevents zone enumeration') but does not disclose prerequisites (e.g., DNSSEC must already be enabled), idempotency, or side effects. It is not misleading but lacks depth.

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 states the action and purpose with no redundant wording. It earns its place without wasting space.

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?

This is a simple tool with one parameter, and the description explains what it does and why. It is concise and generally complete for the tool's simplicity, though it could mention prerequisites or the companion tool for disabling NSEC3.

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 parameter 'domain' is fully described in the schema. The tool description adds no extra parameter semantics, but the baseline is 3 given the high schema coverage.

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 action: 'Enable NSEC3 for a DNSSEC domain'. It specifies both the verb (Enable) and the resource (NSEC3 for a DNSSEC domain), and the parenthetical adds a purpose. This distinguishes it from siblings like unset_dnssec_nsec3 and enable_dnssec.

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 implies usage context by saying 'for a DNSSEC domain', but it does not explicitly state when to use this tool versus alternatives or mention exclusions. No direct reference to unset_dnssec_nsec3 or prerequisites beyond the domain being DNSSEC-enabled is given.

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