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

Beyond the annotations, the description adds a concrete authorization requirement ('email:write') and explicitly declares that the call mutates server state, which also matches readOnlyHint=false. It does not describe side effects beyond 'changes server state,' but the annotations already cover idempotency and destructiveness.

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?

The description is compact and front-loaded: action first, then HTTP method, category, scope, and mutation flag. Only minor redundancy exists in the 'Category: Email' line given the tool name already contains 'email'.

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?

The body is an opaque open object ('Schema not statically declared'), no output schema is available, and the description never explains what account properties can be updated or what a successful response looks like. Annotations cover the safety profile, but for actually constructing a correct request an agent would need external API docs.

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 100%, with id documented as a path parameter and body documented as an application/json object whose schema is intentionally not statically declared. The free-text description adds no field-level meaning, so it neither improves nor degrades the baseline set by the schema.

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 states a clear action and resource ('Update email account') and includes the HTTP PATCH path, so the tool's basic purpose is unambiguous. It does not, however, say which account attributes can be changed or call out the sibling change-password operation, 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 is given about when to choose this PATCH over alternatives such as change_password, create, or delete; there are also no exclusions or preconditions beyond the scope line. The agent is left to infer usage from the tool name and path.

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