get_ticket_offersUse this when the user wants tickets for one event, before quoting. Returns ticket options: provider, checkout link, estimated price, whether entry is free, whether autonomous purchase is supported, next_step, and the purchase policy. On the hosted connector Dizko does not buy tickets: next_step is hand_off_to_checkout.

-}New value: +nullDoes the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnly, idempotent, non-destructive), so the description earns credit for adding real behavior: it does not buy tickets and next_step is hand_off_to_checkout. That is essential context an agent cannot infer from annotations, though auth or rate-limit details are absent.
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?
Three sentences, front-loaded with the trigger condition, and the returns list is compact. The enumeration of return fields is slightly dense but each item is informative and none is filler.
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?
With no output schema, the description usefully enumerates the return fields and flags the key behavioral outcome (no autonomous purchase, handoff to checkout), which is what an agent needs to plan the next call. Permission or error behavior is the only notable gap.
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?
The single event_id parameter is fully documented in the schema (100% coverage), and the description only implies 'one event' without adding format, source, or validity guidance. Baseline 3 is appropriate when the schema carries the parameter detail.
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?
States a specific verb and resource ('tickets for one event') and names the exact return payload, which distinguishes it from quote_ticket_order and purchase_ticket_order by placing it 'before quoting.' An agent can select it without opening the schema.
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?
'Use this when the user wants tickets for one event, before quoting' gives a clear trigger and an implied ordering relative to the quoting/purchase siblings. It does not explicitly name those siblings or state exclusions, so it falls short of a full when/when-not rubric.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
