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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the mutation profile is known. The description adds genuinely useful context beyond that: the API token will be exposed in the AI conversation, and authentication prerequisites are spelled out. It does not describe reversibility or what 'connecting' changes on the domain, keeping it short of a 5.

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?

Front-loaded with the action and purpose, followed by a security warning and the access requirement. Every sentence carries weight, though the ACCESS paragraph is somewhat long for what it conveys.

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 a 2-param tool with full schema coverage and annotations, the description covers purpose, the security implication of passing a token, and the auth prerequisite. No output schema exists, so no return-value explanation is required; the main omission is what changes on the domain after connecting.

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 100%, so both parameters (id as Domain ID, api_token as a DNS-edit token) are already documented in the schema. The description adds no syntax or format detail beyond that, 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?

States a specific verb (connect), resource (Cloudflare API token), and target (a domain) plus the outcome (automated DNS record management). The provider name inherently distinguishes it from siblings like connect_godaddy and connect_dns_provider, though it never explicitly contrasts 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?

The ACCESS block explains prerequisites (Proof account, PROOF_API_KEY, or start_login) which implies when the tool is callable, but it never states when to choose this tool over connect_dns_provider or connect_godaddy. Usage context is present but alternatives are not addressed.

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