create_and_send

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's action (create and send for e-signature), output (returns envelope ID and signing URL), and input constraints (PDF options). However, it lacks details on error conditions, rate limits, or authentication requirements, which would be helpful for a mutation 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 efficiently structured in two sentences: the first states the core purpose and output, and the second clarifies the PDF input options. Every sentence adds essential information without redundancy, making it easy to parse and understand quickly.

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 complexity of a mutation tool with no annotations and no output schema, the description does a good job covering the action, output, and key input semantics. However, it could improve by addressing error handling or authentication needs, which are relevant for e-signature operations. The absence of an output schema makes the return value description valuable.

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%, so the schema already documents all parameters thoroughly. The description adds minimal value by mentioning the PDF input alternatives (pdf_path or pdf_base64), but does not provide additional context beyond what's in the schema. This meets the baseline for high schema coverage.

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 specific action ('create an envelope with a PDF document, add a signer, and send it for e-signature'), identifies the resource (envelope), and distinguishes it from siblings like 'send_envelope' (which presumably sends an existing envelope) and 'create_from_template' (which uses templates rather than raw PDFs). It provides a comprehensive overview of the tool's function.

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 usage by specifying the document input options (PDF path or base64), but does not explicitly state when to use this tool versus alternatives like 'create_from_template' or 'send_envelope'. No exclusions or prerequisites are mentioned, leaving the agent to infer context from the tool name and description alone.

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