validate_in_tableau_public

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

With no annotations provided, the description carries full burden. It states it opens the workbook and detects error dialogs, but fails to disclose behavioral aspects such as whether the tool modifies the workbook, whether it requires user interaction, how long it takes, or what happens to the screenshot after capture. The lack of side-effect clarity (e.g., destructive hint) is a significant gap.

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, front-loaded sentence that efficiently conveys the main purpose. However, it sacrifices necessary detail for brevity, leaving parameter semantics and usage unspecified.

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 tool has 3 parameters, no output schema, and no annotations, the description is incomplete. It does not explain 'Layer 3+4', what constitutes an error dialog, or how the screenshot is returned. The agent would need external context to use it 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?

Schema description coverage is 0%, and the description does not explain any of the three parameters (path, settle_s, screenshot_dir). The term 'settle_s' is ambiguous (likely a delay), and 'screenshot_dir' is not described. Without any clarification, the agent cannot correctly provide 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 clearly states the specific purpose: 'Layer 3+4 validation: open the workbook in Tableau Public, detect error dialogs, and capture a screenshot proving rendered content.' It uses a specific verb (validate) and resource (workbook in Tableau Public), and distinguishes from related siblings like 'open_in_tableau_public' and 'verify_published_workbook' by defining its unique validation layer.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, when not to use it, or how it differs from sibling validation tools like 'validate_workbook_spec' or 'verify_published_workbook'.

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