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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), and the description adds real context beyond them: an access restriction (owners/admins) and the meaning of null values (default copy rendered in English and Spanish) plus the existence of substitution tokens. It does not discuss pagination or ordering, but the added behavioral detail is substantive.

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 the main body is a verbless fragment with a dense parenthetical, so the reader must reconstruct what action is being performed. The 'Owners and admins only' sentence is well placed at the end, but overall the phrasing is harder to parse than its length warrants.

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?

An output schema exists, yet nearly all the description's content restates the returned fields rather than establishing what the tool does or how it relates to update_notification / list_form_notifications. The permission note helps, but the definition leaves the agent without routing guidance for a read-only, zero-required-parameter tool.

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 100% and there is a single parameter, whose workspace_id description already explains sourcing from list_my_workspaces and when it is optional. The description adds nothing further about the parameter, so the baseline 3 applies.

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 names the concrete resource: the workspace setting of the two response notification emails, including sent status, subject/body, recipients and copy tokens. It is specific about content but has no operative verb (no 'list'/'returns'), and it never distinguishes itself from siblings such as list_form_notifications or get_form.

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 only guidance is a prerequisite: 'Owners and admins only.' That is genuinely useful for deciding if the agent can call it, but there is no when-to-use context and no indication of how this differs from list_form_notifications or when to reach for update_notification instead.

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