mf_accounting_list_departments

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

With no annotations and a minimal description, the tool does not disclose behavioral traits such as whether it is read-only, returns paginated results, requires authentication, or any rate limits. The description only restates the basic action.

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 a single concise sentence. However, it is somewhat vague and could benefit from more specificity without becoming verbose.

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 lack of annotations, output schema, and usage guidance, the description is incomplete for an agent to confidently invoke the tool. It does not mention authentication, return format, or any operational context.

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 takes zero parameters, so according to the rules, the baseline is 4. The description does not need to explain parameters, and it appropriately avoids unnecessary detail.

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 '部門一覧を取得する' (retrieve a list of departments) states a clear verb (取得/retrieve) and resource (部門一覧/department list). However, it does not distinguish from siblings like mf_accounting_list_sub_accounts or mf_expense_list_depts, leaving ambiguity about which list tool applies.

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 guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. The agent must infer usage context solely from the name.

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