A4.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds useful behavioral context beyond those annotations: pagination is supported, page_size limits results, and page_token fetches the next page. No contradiction with annotations exists.

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 with no filler. The core purpose is front-loaded, and the pagination guidance is directly actionable. Every sentence earns its place.

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 read-only list operation, the description is complete when combined with the rich schema and annotations: the output schema covers return shape, annotations cover safety, the schema covers parameters, and the description covers purpose and pagination behavior. Nothing essential is missing.

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 description coverage is 100%, so the schema already documents all three parameters. The description's pagination sentence mostly restates what pageSize and pageToken already say in the schema, and it does not add new meaning about projectId. A baseline 3 is appropriate because the schema carries the parameter documentation burden.

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 opens with a specific verb and resource: 'List BigQuery dataset IDs in a Google Cloud project.' This clearly states what the tool does and distinguishes it from siblings like list_table_ids and get_dataset_info. The pagination note further clarifies the scope without ambiguity.

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?

The description gives clear context for when to use the tool and how to paginate results, but it does not explicitly compare it with alternatives or state when not to use it. An agent must infer from the tool name and sibling names that this is for dataset IDs rather than table IDs or dataset metadata.

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

A4/5.0
Disambiguation5/5

Each tool targets a distinct concern: full SQL execution, read-only SQL execution, and specific metadata lookups for datasets and tables. The two SQL tools overlap intentionally but are clearly separated by the read-only restriction and explicit guidance to prefer the read-only variant.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern: execute_sql, get_dataset_info, list_table_ids. The readonly suffix on execute_sql_readonly is predictable and does not break the overall naming convention.

Tool Count5/5

Six tools is a well-scoped count for a BigQuery server: two query tools for read-only and full execution, plus four metadata discovery tools. Every tool serves a clear purpose without unnecessary bloat.

Completeness4/5

The set covers the core BigQuery workflows of running queries and discovering datasets/tables, with execute_sql capable of DDL, DML, and ML operations. Minor gaps exist around job management and project-level discovery, but these are not critical for most agent workflows.
