Quote Ticket Order

quote_ticket_order

Read-only

Use this when the user has chosen a ticket offer, quantity and constraints. Creates a signed, time-limited quote (quantity, ticket type, max total, currency, refund terms, delivery email, stop conditions) and returns a quote_token to pass unchanged to purchase_ticket_order plus the exact confirmation text to ask the user for. Without an integrated provider it only prepares a hand off to checkout.

A4.3/5.0

Behavior5/5

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

Beyond the annotations (readOnly, non-destructive, non-idempotent), the description discloses that the quote is signed and time-limited, that it returns a quote_token to forward unchanged, that it returns exact confirmation text, and that without an integrated provider it only prepares a checkout hand-off. These are exactly the behavioral traits an agent needs and they are consistent with idempotentHint=false.

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

Conciseness4/5

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

Two sentences, front-loaded with the trigger condition before the behavior and return semantics. The parenthetical field list is somewhat dense but every clause carries information an agent needs.

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?

No output schema exists, so the description correctly carries the return-value burden by naming quote_token and the confirmation text. It covers the degraded no-provider mode and the purchase hand-off, leaving only minor gaps around the undocumented boolean/event_id parameters.

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 67% and the description mainly restates parameter names (quantity, ticket type, max total, currency, refund terms, delivery email) without adding format or constraint meaning. 'stop conditions' is mentioned but not mapped to a parameter, and event_id/offer_id/add_to_calendar are not clarified further.

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 and resource ('Creates a signed, time-limited quote') and enumerates the quote contents. It clearly positions itself relative to siblings by naming purchase_ticket_order as the downstream consumer and get_ticket_offers as the upstream source of offer_id.

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?

Explicit trigger condition ('Use this when the user has chosen a ticket offer, quantity and constraints') and an explicit next step ('pass unchanged to purchase_ticket_order'). It does not spell out when NOT to use it or what to do if no offer has been chosen, but the workflow context is unambiguous.

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