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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false and idempotentHint=false, so the safety profile is covered by structured data. The description adds the registry-limited producer constraint and names the produced artifact, but it does not explain why the operation is non-idempotent or what execution entails, which is the one behavioral trait the annotations cannot convey.

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 short sentences, front-loaded with the action, so there is no filler. The terseness tips into under-specification rather than disciplined brevity, and the dense jargon makes the little text present harder to parse.

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 tool with a required nested object, no output schema, no parameter descriptions, and a domain-specific artifact ('producerControl/0.2'), the description does far too little. Naming the artifact helps slightly, but the caller still lacks the request shape, expected result, and workflow context needed to invoke it correctly.

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 0% for two parameters, so the description must carry the semantics. It clarifies that 'producer' must come from the delivered registry, which is genuinely useful, but the required nested 'request' object is left entirely unexplained in both schema and description.

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 names a verb ('Exécuter') and a resource ('un producteur enregistré') plus the returned artifact ('producerControl/0.2'), so it is more than a restatement of the name. However, the vocabulary is opaque jargon (Lens, producerControl/0.2, registre livré) and it never distinguishes itself from sibling tools like law_prepare_answer or law_publish_answer, so an agent cannot readily tell why this step comes first.

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 one implicit constraint – 'Le producteur n'est choisi que dans le registre livré' – but no statement of when to call this versus the many prepare/publish/ask siblings. No prerequisites, ordering, or exclusions are given, leaving the agent to guess at the workflow position.

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