  57. First observed

TDQS

A4.8/5.0
Behavior5/5

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

Annotations (readOnlyHint, idempotentHint, destructiveHint) cover behavioral aspects, and the description does not contradict them. The mention of pagination adds transparency about result streaming.

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

Conciseness5/5

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

The description is concise, with two sentences that state the action and pagination usage. It is front-loaded and contains no redundant information.

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

Completeness5/5

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

The description indicates the output (dataset IDs and BigLake namespaces) and the presence of an output schema (though not shown) means return values are already defined. No additional context is needed for a listing operation.

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

Parameters5/5

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

All three parameters (projectId, pageSize, pageToken) are described in the schema with clear meanings, and the description also references page_size and page_token, achieving 100% coverage.

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

Purpose5/5

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

The description clearly states the tool lists BigQuery dataset IDs and BigLake namespaces in a project, using the specific verb 'List' and identifying the resource. It distinguishes itself from siblings like list_table_ids, which lists table IDs.

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

Usage Guidelines4/5

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

The description provides explicit pagination instructions ('Use page_size to limit results and page_token to retrieve next page') and indicates the tool supports pagination. It does not explicitly contrast with sibling tools, but the purpose is clear enough for typical use.

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