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

Annotations already establish that this is a read-only, non-destructive, closed-world operation, so the description rightly focuses on quote behavior. It adds meaningful context by listing the returned quote contents and stating that the DEV reference is valid for 7 days and that no personal data is required. It does not explain error handling or why the operation is non-idempotent.

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 front-loaded sentence that covers the action, inputs, output fields, validity period, and privacy note without waste. Every clause 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?

With no output schema, the description usefully explains what the quote contains and its 7-day validity. For a simple read-only quote tool with one required parameter, this is nearly complete, though it could clarify default formula behavior or error cases.

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 description coverage is 100%, so all four parameters are already documented in the input schema, including the optional formula, activity, and residence country. The description reinforces that juridiction and formule drive the quote and that no personal data is needed, but it does not add syntax or format details beyond the schema.

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 states a specific verb and resource ('Rend un devis ferme') and scopes it to a jurisdiction and formula, with the returned quote fields enumerated. This clearly distinguishes it from the sibling tools for dossiers, jurisdiction details, jurisdiction listing and case tracking.

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 context implies this tool is used to obtain a firm quote for a given jurisdiction and formula, but there is no explicit 'when to use' or 'when not to use' guidance, nor a named alternative. The note that no personal data is needed is useful but does not fully establish usage boundaries.

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