update_dns_record

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

Describes the preview-only behavior when confirm is false, adding value beyond annotations (which lack this detail). Aligns with idempotentHint and openWorldHint.

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 concise sentences cover purpose and key behavioral trait. No wasted words.

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?

No output schema, and description doesn't explain return format or sequence (preview then call with confirm true). However, essential prerequisites are in schema.

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 40%, but description does not clarify the many undocumented parameters (e.g., name, content, ttl). Only the confirm parameter is elaborated in schema and description.

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?

Clearly states it updates an existing DNS record via partial update. Distinguishes from create_dns_record and delete_dns_record by specifying 'update' and 'partial'.

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?

Explicitly mentions the confirm:true gate for actual mutation vs preview. Could more explicitly name alternatives, but siblings suffice.

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