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

The annotations already declare this as non-read-only, destructive, non-idempotent, and closed-world. The description adds meaningful behavioral detail beyond that: it explains that the tool emails the team again and sends a real email, making the side effect concrete.

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, front-loaded with the core action, and every sentence carries useful information. The final sentence reinforces the important side effect without adding unnecessary length.

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 simple two-parameter action tool with annotations and no output schema, the description is largely complete: it identifies the action, the triggering condition, and the side effect. The main remaining gap is the missing semantics for the required agentId parameter.

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 only 50%, and the description repeats the schema's explanation for userId while giving no meaning for the required agentId parameter. Because agentId is undocumented in both schema and description, the description does not compensate for the coverage gap.

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 states a specific action and resource: re-sending the human-handoff notification for a conversation waiting for a human. It clearly distinguishes the operation from generic sending by naming the handoff-notification scenario, though it does not explicitly contrast with sibling tools such as notification_email.

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 gives a clear usage condition: the conversation must be waiting for a human, and this is a re-send rather than an initial notification. It does not list when-not-to-use cases or name alternatives, but the context is sufficiently clear.

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