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

With no annotations provided, the description carries the full burden of behavioral disclosure. It usefully clarifies that this is a full replacement operation rather than partial update, which is important behavioral context. However, it doesn't mention permission requirements, whether changes are reversible, rate limits, or what happens to the response - significant gaps for a mutation tool.

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 extremely concise - just two sentences that both earn their place. The first sentence states the core purpose, and the second provides crucial behavioral context about full replacement. No wasted words or unnecessary elaboration.

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 8 parameters, no annotations, and no output schema, the description is incomplete. While it covers the full replacement behavior, it lacks information about permissions, error conditions, response format, and how this tool relates to siblings. The description does the minimum viable job but leaves significant gaps.

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 schema description coverage is 63%, and the description adds minimal parameter semantics beyond what the schema provides. The statement 'All fields are required' partially explains the full replacement behavior, but doesn't provide additional context about individual parameters. With moderate schema coverage, the baseline of 3 is appropriate.

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 the verb 'Update' and resource 'DNS record', making the purpose unambiguous. However, it doesn't explicitly differentiate this tool from its sibling 'create_dns_record' or 'delete_dns_record', which would require a 5.

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 by stating 'full record replacement, not partial update', which suggests this tool should be used when completely replacing an existing DNS record rather than modifying specific fields. However, it doesn't provide explicit guidance on when to use this versus alternatives like 'create_dns_record' or 'delete_dns_record', nor does it mention any prerequisites.

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