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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds pagination behavior (hasMore iteration) and a cross-tool dependency, which is useful, but says nothing about the result shape, default page size, or ordering.

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, front-loaded with the purpose and followed by the operational sequence; no filler. The second sentence packs prerequisite and pagination together, which is dense but still readable.

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?

With no output schema, the description does well to mention hasMore, but it leaves the returned item type and the meaning of q unexplained, and it is written in French while the tool name, title and annotations are English. Adequate to call the tool, not complete for using it confidently.

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% with three parameters, so the description must compensate. It only hints at the service parameter by pointing to describe_sales_journeys and at pagination via hasMore; the q search parameter is never explained, nor is the page numbering convention beyond the schema's exclusiveMinimum.

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?

"Lister les éléments du projet pouvant être associés à une action de parcours" gives a verb plus a resource, but "éléments du projet" is vague — the actual set of resources is only inferable from the service enum in the schema. Nothing in the description distinguishes it from siblings like list_collections, list_forms, or list_pages, which it partially overlaps.

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 supplies a concrete prerequisite (read describe_sales_journeys to obtain valid services) and a concrete follow-up (paginate via hasMore), which is real workflow guidance. It does not state when not to use it or how it differs from the other list_* tools, so it falls short of a 5.

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