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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses the shape of the returned report (seven obligations, per-obligation states, identity sheet), which is valuable given there is no output schema, but it says nothing about read-only nature, error behaviour for an unknown immat, or data freshness.

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?

A single dense sentence that front-loads the resource and then enumerates the returned content. Every clause conveys information; the only mild weakness is that the list is a run-on that trails off with an ellipsis.

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 annotations and no output schema, the description compensates reasonably by enumerating the report's contents and the possible obligation states. It is close to complete for a single-key lookup, missing only edge-case and freshness behaviour.

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?

There is a single parameter with 100% schema description coverage, so the schema already explains the immat format (registration number or slug). The description adds no additional meaning about the key, so the baseline 3 for full schema coverage 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?

The description names a specific resource (a copropriété) and details what the response contains: seven compliance obligations with their state, required actions, and the building's identity sheet. It is far more informative than a restatement of the name. However, it never contrasts itself with the sibling tools (search_coproprietes, get_syndic), so sibling differentiation is left to inference.

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 statement of when to use this tool versus search_coproprietes (which presumably locates the immat) or get_syndic. Usage is only weakly implied by the singular lookup key. An agent gets no explicit routing guidance.

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