Set configuration value

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=false, so the safety profile is covered structurally. The description's word 'mutable' merely restates that, adding nothing about persistence, scope, whether the prior value is overwritten, or device-scoping behavior — all important for a destructive mutation.

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?

One short, front-loaded sentence with no padding, so it is concise. But it is under-specified rather than efficient-the sentence is small because it omits necessary content, not because it is tight.

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 destructive, non-read-only mutation with four undocumented parameters and no output schema, a single generic sentence is inadequate. An agent cannot determine valid keys, value typing, or the effect of the device parameters from this definition.

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 four parameters (key, value, deviceId, deviceName), so the description carries the full burden of explaining them. It mentions none — not even the format of key/value or what deviceId/deviceName do in a device-scoped config write.

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?

States a verb (Set) and a resource (a mutable Raccoon compatibility setting), so the basic operation is inferable. However, "Raccoon compatibility setting" is vague about what settings exist or where they live, and it gives no differentiation from siblings like get_config or resource_governor_configure.

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?

There is no explicit when-to-use, when-not-to-use, or alternative named. The only implied guidance is that a 'set' tool changes a value; nothing tells the agent when this tool is preferable to editing a config file or using resource_governor_configure.

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