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

The description says it executes a draft and notifies the team, which are clear mutating side effects, while the annotations declare readOnlyHint=true and destructiveHint=false. Executing a draft and notifying an external team is not a read-only operation, so the description directly contradicts the structured safety hints.

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 terse sentences with no filler, and the operational precondition is front-loaded before the workflow position. The mixed-language phrasing is compact but slightly ambiguous to a non-French reader.

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?

An output schema exists so return values need not be explained, but for a mutation-style tool the description omits what the draft contains, what happens on failure, and what the notification entails. Combined with the annotation contradiction, the agent cannot reliably judge safety or behavior.

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% for the single required parameter action_id. The description never mentions it, so an agent gets no meaning, format, or source for the identifier beyond the bare name in 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 names a specific verb and object ('Execute le brouillon') and situates the tool as step 2 of 2, with the precondition of witness confirmation. It is distinguishable from a cancel counterpart (annuler_action) by intent, though it never names that sibling explicitly.

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 a precondition ('APRES confirmation du temoin') and the ordinal position in a workflow ('Etape 2 de 2'), which implies when to call it. It gives no explicit when-not-to-use guidance and does not name the alternative steps or the sibling tools.

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