journal_ventes_csv

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

With no annotations, the description carries the full behavioral burden. It discloses two real traits: the required accounting permission and the output formatting conventions. However it says nothing about date-range scoping, defaults, pagination, or what 'dossier' controls, leaving meaningful gaps for an unannotated tool.

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 compact clauses with no padding; the format specifics are front-loaded and the permission note is appended efficiently. Nothing is wasted, though it is terse rather than maximally informative.

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 3-parameter export tool with no annotations, no output schema, and 0% schema description coverage, the description is too thin: parameters, defaults, and error/precondition behavior beyond the permission note are all missing.

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 description coverage is 0% and the description never addresses 'debut', 'fin', or 'dossier'. An agent must guess that debut/fin are a date range and that dossier selects a file/entity. The format details given are output traits, not parameter semantics, so the 0%-coverage gap is largely uncompensated.

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 specific verb+resource (exports the sales journal as CSV) and pins down the exact format conventions (semicolon separator, decimal comma, French accounting-software import). This distinguishes it from the sibling journal_ventes, though the differentiation is implied by format rather than stated outright.

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?

It implies the usage context ('tel que l'importe un logiciel de compta français') and states a prerequisite ('Permission comptabilité'), which is useful. But it never explicitly says when to prefer this over the plain journal_ventes sibling, leaving the choice to inference.

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