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

No annotations are provided, so the description carries the full behavioral burden. It mentions pagination and filtering support, but that largely restates the page/limit/type/status parameters already visible in the schema, and it says nothing about ordering, result size, permissions, or default behavior.

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?

A single, front-loaded sentence with no filler; the core action comes first and supporting capabilities follow. It is efficient, though it may be undersized given the omitted behavioral context.

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 four optional parameters and no output schema, the description covers the basic read operation but leaves gaps: no return shape, ordering, or guidance on combining filters. Adequate but with clear room to add value.

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 each parameter is already documented in the schema; baseline 3 applies. The description's mention of deposits/purchases/refunds loosely maps to the type enum but adds no syntax or semantics beyond it.

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 transaction history") and enumerates concrete record kinds (deposits, purchases, refunds), which makes the scope clear. It does not, however, distinguish itself from similar retrieval siblings such as order_history or get_balance.

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?

There is no statement of when to use this tool versus alternatives like order_history or get_balance, and no prerequisites or exclusions. Usage is only implied by the phrase "transaction history".

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