Remove a Google account

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

With no annotations, the description carries the full burden of disclosure. It does state the destructive effect clearly ('delete its stored tokens'), which is useful, but it omits important side effects such as requiring re-authentication, breaking dependent Google tools, or irreversibility of the token deletion.

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?

One sentence with no filler, front-loading the key action. It is appropriately concise for a simple tool, though it could earn a 5 by including a short clause about re-authentication or side effects without becoming verbose.

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 low complexity and single well-documented parameter, the description is mostly adequate, but the lack of annotations and output schema leaves the return value, success/failure behavior, and impact on connected tools undisclosed. For a destructive account operation, slightly more context would make it complete.

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 already provides 100% coverage for the single parameter, describing 'name' as 'Account nickname to remove'. The description adds no further meaning, so the baseline of 3 applies because the schema handles the parameter documentation sufficiently.

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 precise verbs ('Disconnect', 'delete') and a specific resource ('stored tokens'), clarifying that this removes local credential access rather than deleting a Google account. This distinguishes it from sibling tools like google_account_add, google_account_set_default, and google_account_status.

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, nor any indication of prerequisites or consequences. The intended context can only be inferred from the tool name and the word 'Disconnect', which is not proactive enough for an agent deciding between account-management siblings.

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