webmaster_get_host

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

With no annotations, the word 'Read' is the main behavioral signal, implying a non-mutating operation. The word 'exact' adds that lookups are exact-match, but the description does not disclose other behavioral traits such as error handling, authorization requirements, rate limits, or response behavior beyond what an output schema might already show.

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, front-loaded sentence that states the verb and resource without filler, repetition, or unnecessary detail. It is appropriately sized for a simple one-parameter read tool.

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?

For a one-parameter read operation with an output schema and no nested objects, the description is nearly sufficient. It is missing explicit guidance relative to the many sibling tools, but the core information needed to call it correctly is present.

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 only describes host_id as a string with 0% schema description coverage, so the description must compensate. The phrase 'exact Webmaster host identifier' clarifies that the parameter refers to a specific host and that matching is exact, but it does not provide a format, example, or source for the identifier.

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 uses a specific verb ('Read') and a specific resource ('metadata for an exact Webmaster host identifier'), clearly indicating a single-host lookup. It does not explicitly contrast with sibling get_* tools, but the phrase 'exact host identifier' helps distinguish it from list-oriented tools.

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 about when to use this tool versus alternatives such as webmaster_list_hosts or other webmaster_get_* tools. There is no mention of prerequisites, like obtaining a host_id, or exclusions, so the agent must infer usage entirely from the name and description.

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