create_settings_notifications_email

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

Annotations already identify this as a mutating, idempotent, non-destructive operation, and the description's 'Update' is consistent with readOnlyHint=false. It adds the prerequisite of discovering fields via GET/schema, but it does not describe whether the update merges or replaces existing settings, or any other behavioral consequences beyond what annotations provide.

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 short and front-loaded, with each line serving a purpose: the action, the endpoint, and the critical instruction to consult GET/schema. It is slightly terse but not padded, so it earns a strong score without being excessive.

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 tool with a single opaque body parameter and an output schema, the description supplies the key missing context: the exact endpoint and a reliable way to discover the expected payload shape. It does not explicitly exclude the sibling email_test tool or clarify update/replace semantics, but it is reasonably complete for this API style.

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 0%, so the description carries a heavy burden for explaining the single body parameter. It adds that 'body' is the request payload and points the agent to the matching GET or /schema endpoint to discover fields, which is useful but externalizes the needed field semantics rather than providing them.

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 clearly states the action ('Update') and the resource ('email notification settings'), so an agent knows what the tool operates on. It does not explicitly differentiate itself from the sibling create_settings_notifications_email_test, and the tool name says 'create' while the description says 'update,' which creates minor ambiguity.

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?

The description implies the use case: updating the email notification configuration, and it instructs the agent to consult the matching GET or /schema endpoint before supplying a body. However, it does not explicitly state when to use this tool over the sibling test tools or otherwise provide when-not guidance.

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