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

No annotations provided, so description carries the burden. It explains input constraints and enrichment logic, but does not state whether the operation is synchronous or asynchronous, any side effects, or error handling. However, it does mention file size limits and required columns, which adds transparency.

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?

Description is concise with two paragraphs: first sentence states purpose, then follows with requirements, recommendations, file size note, and alternative tool. No fluff or redundant information.

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 output schema exists, return values are covered. The description provides enough context for input and differentiation from siblings. It lacks explicit mention of authorization prerequisites or whether creation is immediate, but overall it is complete for typical usage scenarios.

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 coverage is 100%, so each parameter is described. The tool description adds context beyond schema by specifying that the 'file' parameter should be CSV content (not a path), that the CSV must have a 'name' column, and that additional columns map to attributes. This enhances understanding.

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?

Description clearly states 'Create a new dataset by uploading a CSV file.' It specifies the action, resource, and method. Also explicitly distinguishes from sibling 'append_csv_to_dataset' by stating to use that tool for adding rows to an existing dataset.

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?

Description provides explicit guidance: when to use (creating new dataset), when not to use (use append_csv_to_dataset for appending), and tips on CSV content (require 'name' column, recommend 'domain'/'description' columns for better enrichment, and max file size is plan-dependent).

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