pageSizeNoOptional. The maximum number of results to return in a single response page. If unset, the default page size of 5000 is used.
datasetIdYesRequired. Dataset ID of the table request.
pageTokenNoOptional. Page token, returned by a previous call, to request the next page of results.
projectIdYesRequired. Project ID of the table request.

Output Schema

  57. First observed

TDQS

A4.1/5.0
Behavior4/5

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

The annotations already signal read-only/idempotent/non-destructive behavior, and the description adds the pagination behavior. It does not describe potential errors or permissions, but annotations adequately cover the key side-effect profile.

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 two sentences, front-loaded with the core purpose, and contains no unnecessary detail.

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?

For a simple listing tool with pagination and an output schema, the description is complete: it states the scope, pagination support, and how to use the pagination parameters. The output schema is available, so return-value details are not required in the description.

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

Parameters3/5

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

Schema coverage is 100%, and the description adds semantic meaning for pageSize/pageToken. However, it refers to them as 'page_size' and 'page_token' in snake_case, while the actual schema properties are camelCase, which is a minor mismatch that could cause confusion.

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 action ('List') and the resource ('table ids in a BigQuery dataset or BigLake namespace'), making it distinct from sibling tools like list_dataset_ids or get_table_info.

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?

It provides pagination guidance ('Use page_size to limit results and page_token to retrieve next page') but does not explicitly explain when to choose this tool over alternative siblings such as execute_sql or list_dataset_ids.

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