Quota France Student

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 does convey that the call is informational (displays budget and remaining limits), implying read-only and non-destructive behavior, but it says nothing about whether authentication or a France Student account is required, whether values are live or cached, when quotas reset, or what happens on an unauthenticated call.

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 well-formed sentence with the resource front-loaded and no filler. It is appropriately sized for a zero-argument status tool, with only the minor gap that the key scoping detail (France Student account) trails at the end.

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 zero-parameter read tool with no output schema and no annotations, the description covers what is returned at a high level but omits the return shape, whether a nested budget/limit structure comes back, and the requirement of a France Student account. Adequate but with clear gaps given that no structured fields compensate.

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 input schema has zero parameters, so the baseline is 4. The description correctly implies a parameterless, account-scoped call, though it does not explicitly state that no arguments are needed.

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?

"Affiche le budget de chat et les limites de débit restants" states a clear verb (affiche = displays) and two specific resources (chat budget, remaining rate limits), which distinguishes it from the listed siblings fs_generate_image and fs_list_agents. It is not tautological with the name fs_usage, though it does not explicitly name a sibling it is not.

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 description gives no when-to-use or when-not-to-use guidance and no prerequisites; the only contextual cue is "sur ton compte France Student", which quietly implies a scoped/authenticated account rather than a fleet-wide view. An agent must infer that this is a read-only status check and has nothing telling it what to do instead if this tool is unsuitable.

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