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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the endpoint path and the shape of returned records, but says nothing about pagination behavior or result volume beyond what the schema's page/limit fields imply.

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?

Two tight sentences with zero filler; the core listing purpose and its return fields come first, followed by filtering options and the endpoint. Every clause carries information.

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 returned fields (id, created_at, result, total in cents, is_test, order), which is real added value. Pagination mechanics are left to the schema, which is acceptable, though it stops short of noting anything about result ordering or total counts.

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 (page, limit, with, result, filters, created_after/before) is already documented in the schema. The description only restates the result/date-range/filters options at a high level without adding syntax or defaults, so baseline 3 applies.

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 payment transactions'), enumerates the returned fields, and names the exact filtering dimensions plus the underlying endpoint GET /v1/transactions/. It is clearly distinguishable from the singular cratejoy_get_transaction 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 says how to filter (by result, creation range, or `filters`) but never states when to choose this tool over cratejoy_get_transaction for a single record or cratejoy_list_orders for order data. Usage is implied by the plural 'list' framing rather than stated.

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