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

Beyond the destructive annotation, the description discloses that activation causes enrolled owners to start receiving scheduled emails, texts, and mail, and that doing so uses credits. It also states the approval requirement. It does not explain what happens to already queued or in-flight messages when pausing.

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 two tight sentences with no wasted words. The primary activation effect is front-loaded, followed immediately by the key prerequisite and approval constraint.

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, open-world mutation with no output schema, the description covers the essential side effects, credit usage, and activation prerequisites. A fuller treatment would clarify pause behavior and possibly point to the step-template setup 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%, so the parameters are already documented in the schema, including the required true value for confirm during activation. The description reinforces the approval requirement but does not add parameter-level meaning beyond what the schema already provides.

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 uses a specific action pair, activate or pause, on a clearly identified resource: a workflow. It distinguishes the tool from siblings such as create, get, list, and enroll by focusing solely on lifecycle state changes.

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?

It provides clear conditions for activation: every send step must have a template and the user must explicitly approve. It does not, however, name any alternative tools or say explicitly when not to use this tool, such as directing the agent to set step templates first.

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