list_allowance_reason_codes

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

No nnotations are providedso the description carries the behavioral burden . 'List' from a code list implies a non - damaging lookup and the output schema covers the return shape , but no further details such as authorization , ordering , or pagination are stated . This is minimal yet adequate for a simple listing tool .

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 sentence that states the action , resource , and source standard with no redundancy . It is front - loadedand efficient .

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 the low complexity , zero parameters , and presence of an output schema , the description is essentially complete for selecting and invoking the tool . A brief reference to the sibling check tool would be a nice improvement but is not necessary for correctness .

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?

The tool has zero parameters and an empty schema , so there is nothing for the description to explain about inputs . The baseline for 0 parameters is 4 , and no param info is needed .

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 uses a specific verb ('List') and resource ('allowance reason codes') and nameshte source standard (CEF EN 16931) . This distinguishes it from sibling tools like check_allowance_reason_code and list_charge_reason_codes without requiring schema inspection .

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 commit implies usage: call this tool to enumerate allellowance Reason codes from the code list . However , it does not explicitly contrast with check_allowance_reason_code or other list tools , so thewhen-to -use vs alternatives is left to inference .

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