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

The annotations already indicate readOnlyHint=true and destructiveHint=false, and the description's 'returns' is consistent. No additional behavioral context (e.g., error behavior, authorization needs) is provided, but because the safety profile is covered by annotations, this is neutral rather than misleading.

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 single sentence is dense and front-loaded: the verb, resource, and the conditional on the id parameter are communicated in one clean statement. There is no repetition or filler.

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 one-parameter read with an existing output schema, the description covers the key takeaway: the current versus historical version selection. Combine that with the readOnly and non-destructive annotations, and the agent has enough to call this tool safely and correctly.

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?

With 0% schema description coverage, the description attempts to compensate by explaining that omitting the parameter yields the current effective version while providing 'id' retrieves a historical one. It adds meaningful semantics to 'consentVersionId' but stops short of describing the ID's format or what happens for nonexistent values.

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 uses a specific verb and resource: "returns the currently effective ESIGN consent version", and it clearly differentiates the current vs. historical cases. This distinguishes it from sibling signature tools centered on envelopes or statuses.

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 its use case (obtaining consent documents), but it does not explicitly call out when not to use it or name any alternatives. Sibling tools like signature_get_signature_envelope could be confused with it, but no distinction is drawn.

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