create_site_txt_record

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

No annotations are provided, so the description carries the full burden. It states 'Creates a DNS record,' which implies a write operation, but doesn't disclose behavioral traits such as whether it requires specific permissions, if it's idempotent, what happens on conflicts, or error conditions. The description adds minimal context beyond the basic action.

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 two sentences with zero waste: it states the purpose and constraint efficiently. It's appropriately sized and front-loaded, with every sentence earning its place by clarifying the tool's scope.

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's complexity (5 parameters, nested objects, no output schema) and lack of annotations, the description is minimal. It covers the basic purpose and record type constraint but doesn't address behavioral aspects, error handling, or output expectations. For a creation tool with no annotations, this 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?

Schema description coverage is 100%, so the schema already documents all parameters thoroughly. The description adds no additional meaning about parameters beyond what the schema provides, such as explaining the 'siteId' dependency or 'data' format specifics. Baseline 3 is appropriate when schema coverage is high.

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 action ('Creates a DNS record') and resource ('for a specific website'), and specifies that 'Only TXT records are supported.' However, it doesn't explicitly differentiate from sibling tools like create_site_a_or_aaaa_record or create_site_cname_record, which handle different DNS record types.

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 specifying 'Only TXT records are supported,' which suggests this tool should be used for TXT records rather than other DNS record types. However, it doesn't provide explicit guidance on when to use this versus alternatives like create_site_cname_record, nor does it mention prerequisites or exclusions.

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