fiken_list_account_balances

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

With no annotations supplied, the description carries the full burden of disclosing behavioral traits. It only notes that amounts are in cents, but omits details on pagination, authentication, rate limits, or what operations are performed (e.g., read-only).

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 very concise, consisting of a single sentence plus a note. It front-loads the action but lacks structured detail. While efficient, it is borderline under-specified for a tool with multiple parameters.

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?

Given no output schema and no annotations, the description is too minimal to be complete. It does not explain the return format, pagination behavior, or filtering semantics for parameters like 'fromAccount' and 'toAccount'. More detail is needed for effective use.

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?

Since schema_description_coverage is 100%, the schema already documents all parameters. The description adds no additional meaning to the parameters themselves, though the note about amounts in cents provides context for the output (which is not in the schema). Baseline 3 is appropriate.

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 clearly states it lists account balances for a company, with a specific verb and resource. However, it does not differentiate from similar sibling tools like 'fiken_get_account_balance' or 'fiken_list_accounts', which could cause confusion about when to use this tool.

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?

No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or context for invocation. The description simply says 'for a company' without specifying scenarios or exclusions.

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