set_department

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

No annotations are provided, so the description carries the full burden. It reveals the tool sets a field for the whole week, but does not mention overwrite behavior, permissions, idempotency, or return value. This leaves important behavioral gaps.

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 sentences with no redundancy. First sets purpose, second provides usage guidance. Every word earns its place.

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, no annotations, and moderate schema coverage, the description covers purpose and usage but lacks details on behavior when the field already exists, error conditions, and response format. Adequate but with notable gaps.

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 coverage is 50% (only date has a description). The description adds context for department by referencing list_departments and user confirmation, but does not specify format or accepted values beyond 'code'. For a 2-param tool, the description partially compensates but lacks full semantic clarity.

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 the tool sets the 'Abteilung/Sparte' field for a week. The verb 'Set' and resource 'field for the week containing the given date' are specific. It distinguishes from sibling tools like list_departments, get_week, and set_week_remarks.

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 explicitly instructs to call list_departments first and confirm the code with the user, providing clear when-to-use and when-not-to-guess guidance.

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