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

No annotations are provided, so the description carries full burden but fails to disclose behavioral traits. It doesn't indicate if muting is reversible, requires specific permissions, affects alerting systems, or has side effects like stopping notifications. The single phrase offers no operational context beyond the basic action.

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?

While concise with three words, the description is under-specified rather than efficiently structured. It lacks front-loaded critical information (e.g., what 'mute' means operationally) and wastes no words but fails to provide necessary context, making brevity detrimental to clarity.

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?

Given no annotations, no output schema, and a mutation tool (implied by 'mute'), the description is incomplete. It doesn't explain the muting effect, return values, or error conditions. For a tool that likely alters system state, this minimal description leaves significant gaps in understanding its full context.

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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description doesn't add parameter details, which is appropriate here. Baseline is 4 for zero parameters, as the schema fully covers the absence of inputs.

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 'Mute a monitor' clearly states the verb ('mute') and resource ('monitor'), making the basic purpose understandable. However, it's vague about what 'mute' entails (e.g., silencing alerts, pausing notifications) and doesn't distinguish from siblings like 'unmute_monitor_v1' or 'mute_host', leaving ambiguity in scope.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing monitor), exclusions (e.g., cannot mute already muted monitors), or sibling tools like 'unmute_monitor_v1' for reversal, leaving the agent with no contextual usage cues.

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