download_workbook_twbx

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

With no annotations, the description discloses key behavior: it verifies the `allowDataAccess` flag before downloading, describes the .twbx contents, and states the return value (file path). Missing error behavior, but overall transparent for a simple download 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 concise (5 sentences) and front-loaded with the main action. Each sentence adds value: action, verification, file contents, return value, and next-step tool. No redundancy or fluff.

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?

The description covers the primary use, the verification step, return value, and a related tool. It lacks explicit error handling and prerequisites (e.g., authentication), but given the tool's simplicity and lack of output schema, this is reasonably complete.

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 description never mentions the single `workbookName` parameter. With schema description coverage reported as 0%, the agent gets no guidance on what value to provide. The parameter name is self-evident, but the description fails to reinforce or clarify it.

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 states the exact action: 'Downloads a Tableau Public workbook as a .twbx file for offline analysis.' It specifies the verb, resource, and output format, and naturally distinguishes itself from sibling `get_*` and `unpack_twbx` tools.

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 clear context for when to download (for offline analysis) and directs the agent to use `unpack_twbx` next. It does not explicitly state when not to use it, but the guidance given is adequate.

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