verify_agent_contact_email

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

With no annotations, the description carries the full burden. It discloses a key behavioral trait: 'Does not expose the challenge secret.' However, it fails to mention other important details such as idempotency, side effects (e.g., sending an email), or what happens if the email is already verified.

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 extremely concise: two sentences with no wasted words. The first sentence states the purpose, and the second adds a critical behavioral note. Every word earns its place.

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?

Given zero parameters and no output schema, the description covers the basic purpose and a behavioral note. However, it omits information about return values (e.g., success/failure indication) and prerequisites (e.g., the agent contact email must be set). This leaves some gaps for an agent to fully understand the tool's context.

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 input schema has no parameters, so the description does not need to compensate. The baseline for zero parameters is 4, and the description adds no unnecessary parameter info.

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 tool's function: starting or resending an operator email reply challenge for the active agent contact email. It specifies the action (start/resend) and the resource (operator email reply challenge), distinguishing it from related tools like set_agent_contact and get_agent_contact_status.

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 usage after setting an agent contact email, but it lacks explicit guidance on when to use this tool versus alternatives (e.g., get_agent_contact_status to check verification status). No when-not-to-use or prerequisites are mentioned.

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