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

Beyond the annotations (readOnlyHint false, destructiveHint false), the description discloses idempotency per action_id, a 10-minute expiration, and the required scope 'leads.write'. It also implies it is a mutating operation (executes an action). These are valuable behavioral traits that an agent needs to know, and they are not contradicted by the annotations.

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 concise and front-loaded with the critical 'DEUXIEME etape' context. Each clause delivers distinct information: purpose, usage condition, idempotency, expiry, and scope. There is no wasted wording, and the structure makes the key constraints immediately visible.

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 simple tool with one parameter, the description covers the essential context: purpose, prerequisite condition, idempotency, expiration, and required scope. There is no output schema, but the description does not need to explain return values per rules. The only minor gap is the lack of explanation about obtaining action_id, but this is inferable from the 'second step' context and does not impair correct usage.

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 schema description coverage is 0%, so the description must compensate for the undocumented action_id parameter. It mentions that the tool is idempotent by action_id, which implies action_id is the identifier, but it does not explain what action_id represents, where it comes from (e.g., a previous proposal step), or its format. The basic identification role is clear, but the semantic link to a prior step is missing.

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 clearly states the tool executes a prepared action (e.g., a call reminder request) and is the second step in a process. It distinguishes itself from siblings by indicating it is the execution step versus the proposal (proposer_demande_rappel) or cancellation (annuler_action). However, it does not explicitly name the sibling or the precise action type it handles, so it falls short of a perfect clarity score.

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 description gives an explicit conditional: 'A n'appeler QU'APRES confirmation explicite du visiteur dans la conversation' – it must only be called after explicit visitor confirmation. It also indicates it is the second step, implying a prerequisite from a proposal tool. This is strong usage guidance that prevents misuse.

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