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

No annotations are provided, so the description must disclose behavioral traits. It only says 'Cancel,' which implies a destructive action, but fails to explain consequences like irreversibility, permission requirements, or impact on signers. This is a significant transparency gap for a cancellation tool.

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 no wasted words. It is front-loaded with the core action. However, it is so terse that it sacrifices necessary detail, though conciseness itself is good.

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 destructive action with no annotations and no output schema, the description is incomplete. It lacks context about the envelope's state, the irreversibility of cancellation, or any follow-up behavior. A user would need to search elsewhere for critical operational details.

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 does not mention the 'envelopeId' parameter at all. It does not clarify what the parameter represents or how to obtain it. The description adds no semantic value beyond the schema's bare type definition.

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 and resource: 'Cancel a DocuSign envelope.' The verb 'cancel' is specific and distinguishes this tool from siblings like 'send_for_signature' and 'resend_signature_request'. No ambiguity exists about what the tool does.

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 provides no guidance on when to use this tool versus alternatives. It does not mention when cancellation is appropriate (e.g., envelope not yet signed), prerequisites, or any exclusions. The only hint is the tool name itself.

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