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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only says 'send' via DocuSign but does not explain side effects (e.g., email notification to recipient), authentication requirements, or whether the operation is reversible. Mutating behavior is implied but not detailed.

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 a single, focused sentence with a clear verb-object structure. It conveys the core purpose without unnecessary words, achieving high conciseness.

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 the tool has 6 parameters, no output schema, and no annotations, the description is too sparse. It does not mention what the return value represents (e.g., envelope ID), prerequisites (e.g., document content must be provided), or what happens after sending. The description is far from complete for effective tool invocation.

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 0% and the description adds zero information about parameters. It does not clarify the format of documentContent (e.g., base64, file path), the role of recipientEmail and recipientName, or the difference between message and subject. The description fails to compensate for the schema 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 clearly states the action (send), the resource (document), and the purpose (electronic signature via DocuSign). This distinguishes it from sibling tools like check_signature_status, resend_signature_request, and void_envelope, which address different stages of the signature lifecycle.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention conditions such as 'use when the document is ready for signature' or explicitly contrast with resend_signature_request or void_envelope, leaving the agent without decision support.

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