update_ticket_buyer_settings

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that the tool updates settings, which implies mutation, but it does not disclose whether the update is partial or full replacement, whether null values clear existing settings, whether the event must be in a certain state, or what the response contains. The output schema exists but the description adds no behavioral context beyond the verb 'Update'.

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 a single concise sentence that front-loads the action and resource. It wastes no words, though it could add a brief note about null semantics or the read sibling without becoming verbose.

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?

The tool is a simple 3-parameter update with an output schema, so the description does not need to explain return values. However, with no annotations and 0% schema coverage, the description leaves gaps around null-value behavior, units, and permissions. It is adequate for a basic update call but not fully complete.

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%, so the description must compensate. It does name the two updatable fields (refund policy, checkout time limit), which maps to the refund_policy and checkout_time_limit parameters, and event_id is implied by 'for an event'. However, it does not explain the meaning of null defaults, the units for checkout_time_limit (e.g., minutes), or the format of refund_policy, so the compensation is partial.

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 ('Update') and resource ('checkout settings ... for an event'), and names the two settings being modified (refund policy, checkout time limit). It is clear enough to distinguish from the sibling get_ticket_buyer_settings, though it does not explicitly name that sibling.

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 implies this tool is used when updating checkout settings for an event, and the sibling get_ticket_buyer_settings implies the read counterpart. However, it does not explicitly state when to use this tool versus alternatives, nor does it mention any prerequisites such as the event needing to exist or the user needing permission to modify it.

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