Delete service account

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

With no annotations, the description carries the full burden, and it does disclose one genuine behavioral trait: deletion is 'not immediately reversible after ~30 days,' implying a soft-delete/recovery window. It omits the rest that matters for a destructive mutation – required permissions, what happens to bound keys and IAM bindings, and what occurs after the 30-day window.

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?

Two tight sentences with no filler, and the core action is front-loaded before the reversibility caveat. Appropriately sized for what it conveys.

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 mutation with no annotations, no output schema, and an undocumented required parameter, the description is thin. It notes the recovery window but does not cover permissions, cascading effects on keys/bindings, or failure modes an agent would need before calling it.

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 coverage is 50%, and the one parameter documented with a description in the schema (projectId) is the optional one, while the required 'email' parameter is bare in both schema and description. The description adds no meaning to either parameter, so it fails to compensate for the coverage gap.

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 ('Deletes a service account'), which separates it from gcp_create_service_account, gcp_get_service_account, and gcp_list_service_accounts. It does not explicitly contrast itself with the closely related gcp_delete_service_account_key, so it stops short of full sibling differentiation.

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 on when to use this versus revoking/disabling a service account or deleting its keys, and no prerequisites (needed IAM roles, whether the account must be empty) are stated. The agent is left to infer usage entirely.

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