delete_service_account_api_key

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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false and openWorldHint=true, so the safety profile is covered by structured data. The description adds nothing on top of that — no statement about irreversibility, permission requirements, or what happens to the service account after key 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?

It is short, but this is under-specification rather than conciseness — the single phrase is simply the tool name repeated. There is no front-loaded purpose statement, precondition, or consequence to justify the brevity.

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 destructive, idempotent delete operation with no output schema and two undocumented identifiers, the description supplies none of the missing context (auth scope, irreversibility, effect on dependent keys). Only the annotations carry any behavioral signal, leaving the description substantially incomplete.

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% for both required parameters (service_account_user_id, api_key_id). The description does not compensate at all, offering no format, source, or relationship guidance for either identifier, which is exactly the case where free-text parameter help is needed.

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 is a verbatim restatement of the tool name, capitalizing each word but adding no information. While 'delete service account api key' does identify a verb and resource, it is a tautology against the name/title rather than a description, and it does nothing to distinguish this tool from the many other delete_* siblings.

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?

There is no guidance on when to use this tool versus alternatives such as delete_secret_route, delete_auth_connection, or delete_service_account. No prerequisites, no mention of the create/edit counterparts (create_service_account_api_key, edit_service_account_api_key) that an agent might confuse it with.

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