Update DNS record

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

With no annotations, the description must disclose behavioral traits like idempotency or partial update behavior. It only says 'Update', which is implicit from the name. There is no mention of whether unspecified fields are left unchanged, or any side effects.

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 short and to the point, but the parenthetical '(update_dns_settings)' adds no value and could be removed. It front-loads the core action.

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 the tool has 5 parameters and no output schema, the description is insufficient. It does not explain the update semantics (e.g., partial update, field usage) or the result of the operation. A more complete description would cover these aspects.

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 0%, so the description should explain parameters. It only mentions updating 'by id', implying record_id is used for identification, but does not describe record_aux, record_data, record_name, or record_type. This leaves the agent unsure about which fields are updatable.

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 clearly states 'Update a DNS record by id', which is a specific verb+resource. It differentiates from siblings like dns_add (create) and dns_delete (delete). However, the parenthetical '(update_dns_settings)' is redundant and slightly confusing.

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?

No guidance is provided on when to use this tool versus alternatives such as dns_add or dns_delete. The description does not mention any prerequisites or context for usage.

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