Thêm DNS qua Cloudflare

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

Annotations already declare a non-read-only, non-idempotent, open-world operation. The description adds genuinely new security behavior: the token is single-use and is neither stored nor logged, which is material for how an agent should handle the api_token. It does not cover failure/rollback behavior, but the annotation baseline keeps the bar low.

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?

Two sentences, front-loaded with the usage condition, and the bilingual pairing adds no real bloat since both halves are short and equivalent. Efficient and readable.

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 mutation tool with no output schema, the description covers safety of the token but is thin on the domain_id parameter and on what 'verify' entails or how success/failure surfaces. Given 33% schema coverage, more parameter context was warranted.

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 coverage is only 33% (only idempotency_key is documented), so the description should compensate. It clarifies that api_token is a Cloudflare token and that the domain is being verified, but it never explains what domain_id refers to or its expected format, leaving a real gap.

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?

States a specific verb+resource combo: it configures DNS and verifies the domain using a user-supplied Cloudflare token. This is distinguishable from generic siblings mail_domain_add/mail_domain_verify because it names the Cloudflare-token path, though it never explicitly contrasts itself with them.

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?

It gives a trigger condition ('when the user provides a Cloudflare token'), which implies when this path applies versus the generic add/verify tools. But there is no explicit when-to-use/when-not guidance or named alternative, leaving the agent to infer the routing.

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