TDQS

A3.6/5.0
Behavior3/5

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

Annotations already disclose readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false. The description adds useful context by specifying a seller EIP-191 challenge and the unchanged-proposal condition, but it does not explain state effects, retry behavior, or external dependencies beyond what annotations already mark.

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 definition is a single front-loaded sentence with no wasted language. The action and scoping condition are delivered immediately.

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?

For a one-parameter tool with annotations, the description adequately states the generated artifact and the proposal condition. It could clarify the prepare-vs-accept boundary or next step, but the core information an agent needs to invoke it correctly is present.

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%, and the single intent_id parameter is fully documented in the schema. The description only reinforces the 'unchanged, buyer-signed proposal' condition and adds no syntax or format detail beyond the schema.

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 states a specific verb ('Generate') and resource ('seller EIP-191 challenge') scoped to an unchanged buyer-signed proposal. It is clear what the tool produces, though it does not explicitly differentiate itself from siblings such as prepare_signed_offer or accept_purchase_intent.

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 phrase 'for an unchanged, buyer-signed proposal' gives an implied usage condition, but the description does not state when to use this instead of sibling tools or when not to use it. Guidance is present but relies on inference.

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