add_local_a_record

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

Discloses that the tool replaces any existing entry for the same host, which is a key behavioral trait. However, with no annotations, the description could also mention side effects, required permissions, or failure modes.

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 succinct sentences with no redundancy. Purpose is front-loaded, and every word contributes to understanding.

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?

With an output schema present, the description is fairly complete for a simple mutation tool. It could mention that changes take effect immediately or require admin privileges, but overall it covers the essential operation.

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?

Adds meaning to the 'host' parameter by noting it uniquely identifies the record and references replacement. The 'ip' parameter is left as basic. With 0% schema description coverage, the description provides some context but not detailed format expectations.

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 the action 'Add' and the resource 'local A record', with the mapping 'host -> IP'. Distinguishes from sibling tools like add_local_cname_record, and includes a key behavioral note about replacement.

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?

Implicitly guides usage by specifying that it replaces existing entries, indicating idempotent behavior. Lacks explicit alternatives or when-not-to-use guidance, but the context is clear given the tools name and siblings.

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