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

Annotations declare readOnlyHint=false with destructiveHint=false, so this is a mutation-capable but non-destructive, closed-world tool. The description's 'suivre' (track) reads like a read operation and never explains what side effect justifies the non-read-only annotation, what credentials the token needs, or what happens on repeat calls. It adds only the conversation-sheet scoping constraint.

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 scoping constraint, with no filler. The second sentence largely restates the title, which is the only wasted text.

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 three-parameter, mutation-capable tool with no output schema and zero schema documentation, the description should explain parameters and the effect of calling it. Instead it covers only the usage context, leaving the agent without enough information to invoke 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?

Schema description coverage is 0% across three parameters, and the description mentions none of them. In particular it leaves the near-duplicate 'jeton' and 'token' string parameters completely unexplained, forcing the agent to guess which identifier to supply and what 'simuler' toggles.

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?

It gives a verb and resource ('Suivre un paiement crypto') plus a scoping constraint ('réservé à la feuille de paiement Tchin affichée dans la conversation'), which hints at what it does. But it does not distinguish itself from close siblings such as tchin_crypto, tchin_suivi, etat_paiement or detail_paiement, so an agent cannot tell which one to pick from the description alone.

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?

The first sentence states a real precondition: the tool is only for the Tchin payment sheet displayed in the conversation. That is useful implied guidance, but no alternative tool is named for when that context is absent, and there are no explicit when-not rules.

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