get_user_profile

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

With no annotations provided, the description carries the burden of explaining behavior. It reveals that the tool returns 'the last 21 workbooks with direct URLs,' which is a meaningful behavioral detail. It also lists the types of metadata returned. It does not mention rate limits or error behavior, but for a read-only retrieval, this level of disclosure is adequate.

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 compact, two sentences, with the main purpose stated upfront. It efficiently lists the return contents without unnecessary elaboration. Every sentence contributes to understanding what the tool does and what it returns.

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?

There is no output schema, so the description must explain return values. It does so by listing the returned metadata and the 21-workbook limit. It does not cover potential error scenarios or authentication requirements, but for a simple tool with one parameter and no side effects, 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 'username' parameter explicitly, and the schema description coverage is 0%. It only refers to 'a Tableau Public user,' which implies the input but adds no details about format, constraints, or examples. The schema itself provides the only parameter description, and the description adds little beyond that.

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 tool retrieves comprehensive profile information for a Tableau Public user, enumerating specific data like workbook counts, followers, favorites, and the last 21 workbooks. It distinguishes itself from siblings like 'get_user_profile_basic' and 'get_user_profile_categories' by emphasizing 'comprehensive' and listing a broader scope of fields.

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 says 'Useful for getting a complete overview of a user's Tableau Public presence,' which implies its use case but does not explicitly contrast it with alternative tools such as 'get_user_profile_basic' or 'get_user_profile_categories'. There is no direct when-to-use vs. when-not-to-use guidance.

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