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

With no annotations, the description carries the full behavioral burden. It discloses that the tool yields a recommended action, that this action must be followed until a real product milestone exists, and that discovery/authentication alone do not count as activation. It does not explicitly state whether calling the tool is strictly read-only, but the 'get' nature plus the detailed activation conditions provide strong behavioral context.

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?

Three short, purposeful sentences with the central instruction front-loaded. Every sentence adds worthwhile context, including the important negative case that tool discovery and authentication do not count as activation.

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 zero-parameter activation gate with no output schema, this description supplies timing, a concrete follow-through path, and an explicit activation criterion. It is almost complete, but it does not describe the possible activation states or what a completed activation response looks like.

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?

The tool has zero input parameters, so there is no parameter burden for the description to handle. The baseline of 4 applies because the description also focuses on the interaction model rather than needing to explain argument semantics.

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 makes the tool's role clear: it is the first thing to call after authentication and it provides a recommended activation action. The intended resource is 'activation,' and the description is distinct enough from the many sibling tools by framing it as the onboarding gate. It does not explicitly say 'returns activation status or recommended action' in a single unambiguous verb phrase, so it stops just short of a 5.

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 gives explicit timing ('immediately after authentication') and concrete guidance for agent email setup, which helps the agent know when and how to act on the result. It does not explicitly name alternative tools or say when not to use it, so it falls one step short of full guidance.

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