update_dns_static

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

The description simply repeats the update action without disclosing important behavior like whether the update merges with existing fields or replaces them. Annotations already provide idempotent and non-destructive hints, but the description adds no extra operational context, such as partial update semantics or required permissions.

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 a single, well-formed sentence with no redundant words, making it concise and front-loaded. However, it is so minimal that it borders on under-specification, though each word does earn its place.

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 substantial complexity (16 parameters, multiple DNS record types), a one-sentence description is grossly insufficient. It does not explain how to construct updates, which fields apply to which record types, or how the tool behaves with missing optional fields. The output schema exists, but the agent still lacks essential operational knowledge.

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 has 16 parameters with 0% description coverage, and the description does not compensate by explaining any of them. Fields like cname, text, device, regexp, and the SRV/MX parameters are left entirely undefined, providing no semantic help to the agent.

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 states 'Updates a static DNS entry' with a clear verb and resource, distinctly different from siblings like add, remove, enable, and disable. Though minimal, it unambiguously identifies the action and object.

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 add_dns_static, remove_dns_static, or enable_dns_static. There is no mention of prerequisites, typical use cases, or exclusions.

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