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

With no annotations, the description carries the burden and does disclose important behavior: the API enforces the buyer-signed maximum, the buyer must separately sign the exact terms before payment, and merchant:work scope is required. However, it omits key mutation details such as whether quotes can be resubmitted or updated, idempotency, expiration behavior, and error conditions.

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?

The description is three tightly written sentences with the primary action front-loaded. Each sentence adds material context: submission condition, financial/signature constraint, and authorization scope.

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 financial quote mutation with no annotations, no output schema, and 0% schema description coverage, the definition is too sparse. It explains the high-level workflow but leaves essential invocation details for the five required parameters and the post-submission behavior undocumented.

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 0%, and all 5 parameters are required. The description only loosely gestures at price via 'buyer-signed maximum' and terms via 'these exact terms'; it does not explain ticketId, priceUSDC formatting, deliverable, contentType, or expiresInSeconds beyond what the schema names and constraints already show.

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 states a specific verb and resource: 'Submit one fixed quote', scoped to 'after claiming a ticket'. It is clear what the tool does, though it does not explicitly name a sibling alternative such as accept_work_ticket_quote to sharpen differentiation.

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?

It gives clear usage context: submit after claiming a ticket, with a required merchant:work scope. It also describes the downstream buyer-signature requirement before payment. It does not explicitly state when not to use it or name alternatives, 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.
