mute_off

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

Annotations indicate readOnlyHint=false, destructiveHint=false, idempotentHint=true, openWorldHint=true. The description does not contradict annotations, but it also doesn't add behavioral context beyond what annotations imply. For instance, since it's not read-only't it's a state-changing action, but the description doesn't clarify whether it affects all zones or only the current one. IdempotentHint is true, so calling repeatedly is safe, but that's not stated.

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 extremely concise ('Desactive le mute du Denon.' – one sentence). It is front-loaded with the essential action. Could be slightly more informative but no wasted words.

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 no params and no output schema, the description is minimal but sufficient to understand the basic action. However, it lacks any context about the device state or side effects. Additional context such as 'This only affects the master zone' or 'This is equivalent to toggling mute when mute is on' would improve completeness.

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?

Tool has 0 parameters and schema coverage is 100%, so the description need not add parameter info. The baseline for 0 params is 4, and there is nothing to add, so a 4 is appropriate.

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?

Purpose is clear: unmute the Denon device. The description uses a specific verb and resource, but is minimal and lacks context beyond the action. It distinguishes from siblings like mute_on and mute_toggle by its direct naming.

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?

No guidance on when to use this tool versus alternatives. It doesn't mention that mute_toggle could be used as a generic alternative, nor does it describe any prerequisites (e.g., device must be powered on). A better description would note that this is for explicitly turning mute off.

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