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

No annotations are provided, so the description carries the full burden. It discloses that the domain must be published and that the output includes quantified findings and purchase questions that no page answers, suggesting a read-only analysis tool. However, it does not cover failure behavior, data freshness, or what happens when the domain is unpublished.

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 a single dense sentence that leads with the verb and resource, then lists the three output components. There is no filler, though the phrase about 'questions d'achat auxquelles aucune page ne pourra jamais répondre' is somewhat elaborate.

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 one-parameter tool with no output schema and no annotations, the description gives a reasonable outline of the return payload: weak axes, quantified evidence, and purchase questions. It leaves gaps around valid domain values and error behavior, but the low complexity makes this acceptable.

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 only indirectly defines 'domaine' as a published domain. It provides no format, allowed values, or reference to a sibling tool like secteurs_disponibles for valid inputs. The description adds minimal semantic value for the single parameter.

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 uses a specific verb 'Rend' (returns) and identifies a concrete resource: the weakest axes of a published domain, along with quantified evidence and purchase questions. This makes it distinguishable from siblings like 'secteur' or 'secteurs_disponibles', though it does not explicitly name them.

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 agent_readiness, secteur, or secteurs_disponibles. It implies the tool applies to a 'domaine publié' but does not state prerequisites, exclusions, or how to obtain a valid domain value. An agent must infer context from the name and sibling list.

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