A4.2/5.0

Behavior4/5

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

Annotations already cover readOnly=false, idempotent=false, destructive=false, and closed-world behavior. The description adds meaningful context: the quote expires, shows estimated/maximum credit reservation, and does not charge or call a model. It does not explain the idempotency/confirmation protocol, but it adds substantial value beyond 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?

Three compact sentences, front-loaded with purpose and sequencing, and every sentence adds a distinct constraint or boundary.

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

Completeness3/5

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

The tool is complex: nine parameters, seven required, low schema coverage, and hidden retry/confirmation behavior. The description gives the high-level flow and no-charge guarantee, and an output schema exists, but it does not explain how to obtain or use _confirmationCapability or how _idempotencyKey and requestId should be handled.

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

Parameters2/5

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

Schema coverage is only 22% for nine parameters, so the description must compensate. It maps some concepts—saved idea, exact plan version, owned reference IDs—but leaves messageId, requestId, variationCount, the idempotency key, and the confirmation capability unexplained.

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?

States a specific verb ('Prepare') and resource ('native expiring image quote for one saved AI image idea'), with scope ('exact plan version and owned reference IDs') and an explicit boundary against imageGenerationStart.

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

Usage Guidelines5/5

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

Explicitly places the tool before imageGenerationStart and clarifies that it neither calls an image model nor charges credits, so an agent can see when to invoke this versus the generation start step.

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