set_drive_tag

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does not mention whether tags are overwritten, whether the operation is reversible, any permission requirements, or what the response contains. As a mutation tool, this lack of transparency is a notable gap.

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, action-first sentence that delivers the core purpose without any fluff or repetition. It front-loads the verb and object, and the parenthetical example adds value without bloating the text.

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 no output schema and no annotations, the description plus schema are only minimally sufficient. It does not explain how to obtain drive IDs (though get_drives exists), what effects a tag has, or any failure modes. It is adequate for a simple tool but leaves several important 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 each parameter is already documented. The description adds example tag values but no deeper semantics or relationship between parameters. It does not mention the 'vin' parameter or its default behavior, leaving the schema to carry that information.

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 ('Sets a tag') and the target resource ('on one or more drives'), with concrete examples of tag values. It is easily distinguished from sibling tools, which are primarily vehicle controls or getters, and there is no other drive-tagging tool.

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 (tagging drives) but does not explicitly state when to use it versus alternatives or when not to. No exclusions or prerequisites are mentioned, though the sibling context makes the purpose fairly obvious.

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