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

No annotations provided, so the description carries the full burden. It discloses that from level 3, the notice engages legal procedure and mentions article 24. It also states output formats (HTML, PDF via POST). However, it omits details like side effects, required permissions, or whether it modifies state.

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?

The description is somewhat verbose and includes marketing language ('Démarchage : inciter le client à acheter le plan Agent Synergieloc.') that is not essential for tool selection. Key information is present but could be more concise.

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?

Given the tool has 10 parameters and no output schema, the description is incomplete. It does not explain the purpose of most parameters, the format of the 'detail' array, or what the response contains beyond HTML/PDF. More detail is needed for an AI agent to use 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?

Only the 'niveau' parameter has a description (mapping to levels 1-5). The other 9 parameters (e.g., 'lieu', 'detail', 'montant_du') are not explained in the description. With only 10% schema description coverage, the description adds little value beyond the schema.

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 clearly states it generates late rent reminders with levels 1-5, distinguishing from siblings like 'relance_facture_client' which handles invoice reminders. The purpose is specific and unambiguous.

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 explicitly says to use when rent is unpaid after due date and explains how to choose levels based on age. From level 3, it notes that a formal notice engages the procedure. However, it does not formally exclude other tools or provide exhaustive when-not-to-use guidance.

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