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

No annotations are supplied, so the description carries the disclosure burden. The 'get'/'Resume' phrasing signals a read-only summary and the exclusion of dossier submission reveals a boundary, but the description never says what the overview actually returns, whether it is cached/static, or how it relates to the other tools' data. Adequate but thin 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 short sentences, the summary statement front-loaded and the exclusion placed after it so an agent reads the purpose first. No filler, though the first sentence is a compressed content list rather than a full declarative statement of what the call returns.

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, no-output-schema tool the description is nearly sufficient: it names the scope and one prohibition. What is missing is a clear statement of the return content or shape, which matters more here because no output schema exists to describe the response.

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 (empty object schema, additionalProperties false), so there is no parameter meaning to explain. Baseline 4 applies; the description correctly wastes no words on inputs.

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 pairs the verb 'Resume' (summarize) with the resource 'CreditLabs' and enumerates what the overview covers: credit business-introducer activity, editorial pages, and indicative simulators. That content list also implicitly separates it from siblings like list_editorial_sources and list_simulators, which expose individual sections rather than a whole-site summary, though the distinction is only implied.

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 gives one explicit negative rule: 'N'utilise pas cet outil pour deposer un dossier' (do not use this tool to submit an application/file). However, it never states the positive condition for choosing this tool over the sibling list_* or calculate_* tools, nor does it name an alternative for dossier submission, leaving the when-to-use guidance only half covered.

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