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

With no annotations the description carries the full burden, and it does disclose meaningful side effects: it sends invitations and generates per-signatory links, and it documents the failure mode when pdfPath/signataires are absent. It omits permissions, idempotency, and the demo/prod environment behavior, so it is strong but not exhaustive.

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 sentences, front-loaded with the action verb and its consequences, followed by the hard requirement. No filler; every clause adds information about behavior or preconditions.

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 7-parameter mutation tool with no output schema and full schema coverage, the description supplies what the structured fields cannot: the real-world side effects and the mandatory inputs. Return values need not be explained (no output schema), and the 'no link returned' note covers the key outcome, though environment/auth context is absent.

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 100%, so the schema already documents each parameter; baseline is 3. The description usefully reinforces that pdfPath and signataires are truly required (the schema lists 0 required) and ties the signature zone to the box concept, but adds no syntax or format detail 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 gives a specific verb and resource ('DEPOSE REELLEMENT le document prepare dans Tracea Sign') and enumerates the concrete actions performed (creates signatories, places the signature zone, produces a per-person link, sends invitations). It implies contrast with a mere check via the capitalized 'REELLEMENT', but never names a sibling tool such as tracea_check_demarche, so differentiation is left implicit.

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 states the operating condition that pdfPath and signataires are mandatory and that without them no link is returned, which effectively tells the agent when the call can succeed. However it offers no explicit when-to-use/when-not guidance relative to the other tracea_* tools or prerequisites like prior preparation.

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