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

Annotations already signal mutation (readOnlyHint=false), idempotency, and non-destructiveness. The description adds meaningful context beyond those: the buyer must complete a payment link to place the order, and if payment is already settled, acceptance confirms the order. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. The core behavior is front-loaded, and the settled-payment nuance is a compact addendum. Every sentence earns its place.

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

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

For a simple two-parameter tool with annotations covering safety and idempotency, the description explains the key return values and the payment-flow behavior. It does not cover error handling for non-ready quotes, but that is a minor gap given the schema already constrains the input.

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

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

Schema description coverage is 100%, so both rfq_id and confirm are already documented in the schema. The description reiterates the 'ready' status requirement but adds no new parameter-level meaning beyond what the schema provides.

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

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: 'Accepts a ‘ready’ quote.' It then states the outcome—returns an order_id and a secure payment link—and clarifies the settled-payment edge case. This clearly distinguishes it from sibling tools like get_quote or submit_rfq.

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

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

The description gives clear context: only quotes with status 'ready' should be accepted, and it explains the flow after acceptance. It does not explicitly name alternatives or state when not to use the tool, but the ready-status constraint is a practical usage rule.

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