A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is well covered. The description adds that the response includes timestamps and resource details, which is useful but not extensive. It does not describe pagination behavior, but the schema covers pageToken and pageSize. No contradiction exists between description and annotations.

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 concise sentences with no filler. The core action and scope are front-loaded, followed by helpful detail about returned fields and required inputs. Every sentence earns its place.

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

Completeness4/5

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

Given the robust annotations, complete schema coverage, and presence of an output schema, the description is largely sufficient for correct invocation. It states the resource, scope, required inputs, and key returned fields. It does not explicitly address pagination or alternative sibling usage, but those are either covered by the schema or secondary for a list operation.

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 four parameters clearly. The description mentions 'Requires project and region as input,' which restates schema-level requirements without adding new meaning. It does not elaborate on pageSize or pageToken behavior beyond what the schema provides, so the description adds only marginal value.

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

Purpose4/5

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

The description clearly states a specific verb and resource: 'Lists Compute Engine Commitments in a region,' which distinguishes it from list_commitment_reservations by resource type. It also enumerates the details returned, giving an agent a clear sense of scope. However, it does not explicitly contrast itself with sibling tools, so it falls short of full differentiation.

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 implies usage context by stating it lists commitments in a region and requires project and region as input. It does not explicitly say when to prefer this tool over alternatives such as list_commitment_reservations or get_commitment_basic_info. The guidance is adequate but mostly implied rather than explicit.

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