Thêm DNS qua Cloudflare

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

With no annotations provided, the description carries the full behavioral burden. It does well by disclosing that the token is single-use, not stored, and not logged, and that the tool modifies DNS and performs verification. It stops short of describing failure modes or DNS propagation behavior, but these are secondary to the main security-relevant disclosure.

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 compact, front-loaded with the triggering condition and main effect, and contains no filler. The bilingual phrasing is justified for mixed-language users, and the security note is integrated without bloating the entry.

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?

The description covers the core action and token-security behavior, but omits important context such as prerequisites (e.g., whether the domain must already exist, whether a Cloudflare zone is required), expected return/status information, and error behavior. Since there is no output schema and no annotations, these gaps matter for reliable agent invocation.

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 description adds meaning beyond the schema by identifying api_token as a user-provided Cloudflare token that is used once and never logged, and by implying that domain_id is the target domain. However, schema coverage is only 33%, and the description does not clarify where domain_id comes from or how it relates to the mail-domain lifecycle, so compensation is only partial.

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 states a specific action: when a user provides a Cloudflare token, add DNS records and verify the domain. It clearly distinguishes this from sibling tools like mail_domain_add and mail_domain_verify by making Cloudflare automation the central resource and process.

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 phrase 'Khi người dùng cung cấp token Cloudflare' explicitly names the triggering condition: use this when the user supplies a Cloudflare token. It does not name sibling alternatives or state when not to use them, but the context is clear enough for an agent to recognize the intended usage.

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