TDQS

A4.2/5.0
Behavior4/5

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

Annotations declare the mutation/idempotency profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false), and the description adds value beyond them by stating 'This does not call an image model or charge credits' and that the quote is 'expiring'. It does not explain the confirmation-capability handshake or what happens when a quote lapses, which the schema only hints at.

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 tight sentences with no filler, front-loaded with the action and scope, followed by the operational ordering hint and the cost disclaimer. 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?

With an output schema present, return-value explanation is unnecessary, and the description covers the key concerns for a quote/preparation step: credit reservation, no model call, no charge, expiry. The main gap is the confirmation/idempotency retry flow, which is only covered inside the schema and not surfaced for the calling agent.

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 only 22%, so the description must carry more weight. It loosely maps meaning onto expectedVersion ('exact plan version'), referenceAssetIds ('owned reference IDs') and ideaId ('one saved AI image idea'), but says nothing about variationCount, requestId or messageId, leaving several required parameters unexplained in both places.

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 gives a specific verb and resource ('Prepare a native expiring image quote') scoped to 'one saved AI image idea at the exact plan version and owned reference IDs'. It also explicitly distinguishes itself from the sibling imageGenerationStart by naming it, so an agent can separate the two without opening schemas.

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?

It states the sequencing rule clearly: show the estimated/maximum credit reservation 'before requesting imageGenerationStart', which names the alternative tool and the condition that leads there. There is no explicit when-not or failure guidance (e.g. what to do if the quote expires), so it falls short of a 5.

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