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

Annotations already declare this a safe, idempotent, read-only, closed-world operation, so the safety burden is lifted. The description contributes only the fixed scope (ten families) and the inclusion of recent counts; it says nothing about caching, freshness of the counts, or output shape, leaving the disclosure modest.

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, front-loaded with the scope, zero filler words. The bilingual repetition is redundant textually but is plausibly justified for a French/German/Italian/English service, so it costs little.

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?

For a trivial fixed-cardinality read tool with annotations covering safety and a fully documented enum parameter, the description supplies enough scope and content detail. Nothing critical is missing, though it could note that the returned counts are recent/rolling demand volumes.

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 single parameter has 100% schema description coverage including an enum and default, so the schema carries the semantics. The description never mentions the langue parameter, adding no meaning beyond what the schema already provides; baseline 3 applies.

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?

States a specific verb and resource (list the ten trade families) and even enumerates all ten families, plus what is returned (identifiers and recent counts). That makes the tool's identity unambiguous, though it never names a sibling to contrast with, so an agent must infer differentiation from content alone.

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?

No explicit when-to-use or when-not-to-use guidance and no mention of alternatives such as chercher_demandes. Usage is only implied by the fact that it returns family identifiers and counts, which an agent would need to filter demandes by trade.

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