Enable DNSSEC for a Cloudflare zone

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

Annotations already declare non-read-only, idempotent, non-destructive, open-world, so the safety profile is covered. The description adds real context beyond that: enabling is inert until a DS record is published at the registrar, and the call returns that DS record — useful for an agent planning follow-up steps. It does not mention required token permissions.

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; the action comes first and the caveat second. Every clause carries information the agent needs.

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?

For a two-parameter, fully documented, output-schema-backed mutation with rich annotations, the description covers what it does and the key downstream dependency (registrar DS publication). Only missing piece is any permission or zone-state prerequisite.

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%, with both zone and account fully documented in the schema. The description adds no syntax or format guidance for either parameter, so the baseline 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?

Names a specific verb and resource ("Turn DNSSEC on for a zone") that is unmistakable and naturally pairs against the sibling cloudflare_zone_dnssec_disable. It does not explicitly name the disable sibling, but the operation is unambiguous.

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 action plus the caveat that the change is harmless until the registrar publishes the DS record, which tells the agent this is step one of a two-step workflow. There is no explicit statement of prerequisites (e.g. zone must be active) or of when to prefer the disable sibling.

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