Verify that a published Tableau workbook URL is accessible and responds correctly, confirming it is live and reachable.

Instructions

Layer 5 validation: load a public Tableau URL and confirm it responds. Read-only.

Behavior3/5

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

States it is read-only, which is crucial for safety. However, with no annotations provided, the description should disclose more behavioral traits such as error handling, timeout behavior, or what constitutes a successful response. The current description is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise, using a single sentence. It is front-loaded with 'Layer 5 validation', which may be jargon, but overall the structure is efficient. Could be slightly improved by moving the important 'read-only' claim earlier.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one parameter, no output schema), the description covers the basic action but lacks completeness. It does not explain what 'confirms it responds' means (e.g., HTTP status 200) nor how the output signals success or failure. Also fails to differentiate from siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter 'url' receives minimal additional meaning: it is described as a 'public Tableau URL'. With 0% schema description coverage, this is insufficient. The description should specify expected format (e.g., must start with 'https://public.tableau.com'), but does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool loads a public Tableau URL and confirms a response. It identifies the resource (public Tableau URL) and action (verify). However, it does not explicitly differentiate from sibling tools like validate_in_tableau_public, which may perform similar checks, and the jargon 'Layer 5 validation' is not explained.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies usage for verifying a published workbook is accessible, but provides no guidance on when to use this tool over alternatives (e.g., validate_in_tableau_public). No exclusions or prerequisites are mentioned, leaving the agent to infer context.

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