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

With no annotations, the description carries the full burden, and it does disclose one behavioral trait: the output contains no personal data ('aucune donnee personnelle'). It does not state whether the operation is read-only, whether it requires authorization, or how the counters are scoped, so the disclosure is partial.

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 short sentence with no filler, front-loading the return value and appending the privacy note. Efficient, though the parenthetical slightly interrupts the core statement.

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?

No output schema exists, so the description must convey the return shape, and it does indicate the response is counters of prepared entries. However, it leaves the domain of those counters and the tool's relationship to the action-related siblings ambiguous, which matters for correct invocation.

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 tool takes zero parameters, so the schema has nothing to document and the description's lack of parameter detail is expected. Baseline 4 applies for a no-parameter tool.

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 verb and resource ('Je renvoie les compteurs des ecritures preparees'), so it is not a pure tautology. However, the resource named ('ecritures preparees') does not obviously map to the tool name 'statut_actions', and there is no differentiation from siblings like confirmer_action or annuler_action. An agent could reasonably wonder whether this is accounting counters or action-status counters.

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 a sibling, no prerequisites, and no exclusions. The description merely states what is returned, leaving the agent to infer the context of use.

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