configure_fiscal_year

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 only indicates a write/configuration action but does not disclose any side effects, reversibility, permission requirements, or impact on existing data. This is minimal transparency.

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 sentence, front-loaded with the purpose, and contains no fluff. It is concise but perhaps too brief to fully compensate for missing behavioral and parameter details.

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?

The tool is simple with one parameter and no output schema, but it is a configuration action with potential side effects. The description does not mention return values, errors, or prerequisites, making it incomplete for an agent to safely invoke without further 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 schema has one parameter with 0% description coverage. The description explains that 'start_month' represents the month number for the fiscal year start, adding some meaning beyond the parameter name. However, it lacks constraints like allowed range (e.g., 1-12) or examples, so it is only partially helpful.

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 configures the fiscal year start month, using a specific verb ('configurer') and resource ('mois de debut de l'exercice fiscal'). It distinguishes itself from sibling configuration tools by targeting this unique fiscal-year setting.

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 mention of prerequisites or contextual conditions. The description simply states the action without providing usage context.

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