send_agent_otp

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

No annotations provided; description only states action without disclosing side effects, rate limits, precondition requirements (e.g., email existence), or success/failure behavior.

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?

Single sentence with no redundancy; front-loaded with verb and resource. Every word serves a purpose.

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 OTP-sending tool with one parameter and no output schema, description is nearly complete. Minor improvement could mention relation to verify_agent_otp.

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 description coverage is 100%; description adds no further meaning beyond confirming the email parameter's role. Baseline 3 is appropriate.

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?

Description clearly states the tool sends a 6-digit OTP to the customer's email for in-chat authentication. It uses specific verb 'sends', identifies the resource, and differentiates from sibling tools like verify_agent_otp.

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?

Description provides context ('for in-chat authentication') implying use alongside verify_agent_otp, but lacks explicit when-to-use or when-not-to-use guidance or alternatives.

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