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

Annotations already indicate a non-read-only, non-idempotent write operation. The description adds no meaningful behavioral detail for the create action itself, such as duplicate handling, required permissions, or return data. The update/delete details are mostly irrelevant to the flattened create operation.

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 bulleted structure is compact and scannable, but it includes update and delete actions in a create-specific flattened tool, which is extraneous and potentially misleading. Abbreviations like 'opc' and Portuguese phrasing reduce clarity for non-Portuguese agents.

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?

With no output schema, weak annotations, and a nested data parameter, the description should explain return values, invocation prerequisites, and the exact role of 'account'. It explains the data object reasonably well but leaves these important aspects unaddressed.

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?

The schema provides zero descriptions, so the description compensates by listing meaningful data-object fields: required name and docx_url/base64_docx, plus optional first_signer, lang, observers, folder_path/folder_token, and redirect_link. However, the 'account' parameter is never explained, and 'template_token' is only contextualized through the irrelevant update/delete actions.

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 'create (data): cria template DOCX', identifying the specific action and resource. The '[Flattened action: create]' note anchors the tool's scope, though including update/delete actions alongside creates some confusion.

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?

There is no explicit guidance on when to use this tool versus sibling tools like zapsign_templates_write_update or zapsign_templates_write_delete. The description lists update/delete actions but does not clarify that this flattened tool is only for creation.

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