Toggle DNS record cloud (CDN proxy)

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the [WRITE] convention tag and the official API endpoint, but says nothing about idempotency, error/edge behavior, or side effects beyond what annotations provide.

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 short sentences, front-loaded with the [WRITE] marker and the core action, with the endpoint appended compactly. No wasted prose.

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 small 3-parameter mutation with no output schema, the description covers purpose and endpoint adequately. It omits how the operation relates to update_dns_record and what happens to the record's other attributes, leaving some gaps for a write tool.

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 67%; cloud and record_id are documented in the schema, and the boolean semantics of cloud are already explained there. The description adds no parameter meaning beyond the schema, so the baseline of 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 (toggle) and resource (cloud/proxy status of a DNS record), which is clear and distinct from generic record CRUD. It does not, however, explicitly distinguish itself from update_dns_record, which could plausibly also change the cloud flag.

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 (toggle CDN proxy on/off) but gives no explicit when-to-use versus alternatives such as update_dns_record. No prerequisites or conditions are stated, leaving routing to inference.

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