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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds the authorization constraint (workspace owners only) and narrows the target to email/password accounts in a connector project, which is genuine added context. It does not disclose downstream effects, such as whether credentials, connections, or sessions tied to the account are also removed.

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 short sentences, zero filler, with the action stated first and the permission constraint second. Every sentence earns its place.

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 simple two-parameter destructive tool whose annotations already carry the destructive and idempotency signals, the definition covers action, target, and authorization adequately. The main residual gap is consequences of deletion and how it relates to sibling tools.

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%: project_id is documented, while email relies only on format and pattern constraints. The description compensates partially by framing email as the email/password account identifier and project_id as a connector project, but adds no format or lookup semantics beyond that.

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 ('Delete') and resource ('email/password account from a connector project'), which distinguishes it from siblings like reset_connector_account_password, list_connector_accounts, and add_connector_account. It stops short of explicitly naming those alternatives, so it is clear but not maximally differentiated.

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?

'Workspace owners only' gives a clear eligibility prerequisite, which is useful. However, there is no explicit guidance on when to choose this over reset_connector_account_password or remove_member, nor what happens if the account does not exist.

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