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

Annotations already declare destructiveHint=true, so the bar is lower. The description does add real mechanism beyond that: "tous les paramètres à conserver" hints that this is a full replacement and that omitted settings are dropped, which is the key behavioral fact. However, it states this obliquely and never says plainly what happens to settings left out, nor whether permissions or a prior read are required.

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 with no filler, and the core action is front-loaded. The second sentence is dense but earns its place by carrying the read-then-write instruction.

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?

This is a destructive, full-replace mutation over an arbitrary nested object with no output schema and no documented keys. The description never explains what the settings object should contain or what the result of the call is, so an agent cannot reliably construct a safe payload from it. The language also differs from the surrounding English tooling, adding interpretation friction.

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% and the settings parameter is a free-form nested object with additionalProperties, so the schema explains nothing. The description partly compensates by indicating name plus the complete set of settings must be supplied, but it never enumerates or hints at the valid setting keys, leaving the object's shape entirely undisclosed.

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?

"Enregistrer les paramètres du projet" gives a verb plus resource, but it says "projet" while the tool is named and annotated for workspace settings, leaving a small terminology mismatch. It also does not distinguish itself from the sibling get_workspace_settings, so an agent must infer the write-vs-read split from the name 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?

"Relire puis fournir..." implies a read-before-write workflow, which points at pairing with get_workspace_settings, but this is only implied. There is no explicit statement of when to use this versus the getter, no preconditions, and no warning about when not to call it.

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