get_dns_record_tool

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

No annotations are provided, so the description carries the disclosure burden. 'Get' clearly implies a non-mutating read, and it notes that DNS record details are returned, but it says nothing about auth/permission requirements, error behavior for an unknown ID, or read consistency. Adequate for a simple read, but not rich.

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?

Front-loaded one-line purpose followed by a tidy Args/Returns block; every line carries information. Slightly formulaic structure but 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?

An output schema exists, so the description reasonably omits return-field detail. Both required params are documented with formats, which is what an agent needs to invoke it. The only gap is guidance on choosing this tool over list_dns_records_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 0%, so the description is the only source of parameter meaning – and it documents both params with a format constraint ('32-character hex string') that the schema itself lacks. That is real value beyond the schema, though it stops short of distinguishing zone_id from record_id scoping.

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 and resource ('Get a single DNS record by ID'), which clearly separates it from list_dns_records_tool and the create/update/delete DNS siblings. It does not, however, name an alternative or scope condition, so differentiation is implied via the name rather than spelled out.

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 when-to-use or when-not-to-use guidance. An agent must infer that this tool is for fetching one record when it already holds a record_id, versus list_dns_records_tool when it does not. Nothing in the description states prerequisites or routing logic.

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