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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds real context beyond that: it discloses paging behavior ('Paged') and enumerates the returned fields (attendee name, ticket type, price, check-in state, seating), which matters because no output schema exists.

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?

One dense, front-loaded sentence plus the REST endpoint reference; nothing is padded or redundant. The scope, filters, return fields, and paging all appear in a single pass.

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 read-only list tool with full schema coverage, the definition supplies what structured fields lack: the returned field set and the paging trait. The only gap is the absence of guidance on how overlapping list tools differ.

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 every parameter including enum values and ISO 8601 format is already documented. The description only loosely gestures at the date and status filters, adding no format or syntax detail beyond the schema.

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 ('List the tickets (attendees) for an event'), clarifies the plural collection scope, and enumerates the returned fields. The singular sibling get_ticket and the related list_orders are implicitly differentiated, but no sibling is named explicitly.

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 phrase 'optionally one date of it and complete or cancelled only' hints at the available filter dimensions, but never states when to prefer this list tool over humanitix_get_ticket or humanitix_list_orders, nor any prerequisites. Usage is only implied.

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