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

Annotations already declare destructiveHint, idempotentHint, and openWorldHint, yet the description adds substantial context: confirmation is mandatory, permissions are enforced across workspace/project/account, and the provider returns a queued job that does not report completion until success. The idempotency mechanism (reuse requestId on retry) is explained concretely rather than left to the annotation.

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 with the core action and confirmation requirement, and each sentence carries operational value. The sentence about item updates requiring the current version from get_tasks/get_items/get_workspace is somewhat off-topic for a trash operation with no version parameter in the schema, which is minor noise.

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, the description correctly explains that the call returns a queued job rather than a completion signal, which is the key expectation an agent needs. It does not mention polling get_operation or otherwise how to learn the job's outcome, which is a modest gap for a destructive async 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 description coverage is 0%, so the description must compensate, and it largely does: 'confirm' is explained as required explicit confirmation, 'requestId' is explained as unique-and-reused-on-retry, and 'id' is implied to identify the authorized Google file. It never explicitly ties the id to a UUID file identifier, leaving a small gap for a fully undocumented parameter set.

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 ('Queue moving an authorized Google file to trash'), including the scope qualifier 'authorized' and the async nature of the action. This is clearly distinguishable from siblings like google_create, google_export, and item_archive without opening any schema.

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?

Gives actionable usage context: explicit confirmation is required, and requestId must be unique and reused on retries of the same action. It stops short of naming alternatives or stating when NOT to use this tool (e.g., versus item_archive for internal items), so it earns a 4 rather than a 5.

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