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

Annotation Contradiction: annotations declare destructiveHint=true, but the description describes a reversible suspension ('Pause...paused=true', 'still receives pings'), which is not destructive. The description does add context about alert suppression, but this direct conflict with the destructive hint is severe.

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 sentences, front-loaded with the action and effect, no filler. Every word contributes to understanding the tool's behavior.

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 one-parameter tool with no output schema, the description covers the essential behavior: alerting stops, pings continue. A brief mention that this is reversible via resume_monitor would be slightly more complete, but it is not strictly necessary.

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 100%, and the id parameter is documented as 'Monitor UUID.' The description adds no parameter-specific detail beyond the schema, which is acceptable under the baseline for full schema coverage.

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 states a specific verb ('Pause'), a clear resource ('a LastPing monitor'), and the immediate effect ('stops alerting'). This clearly distinguishes it from siblings like resume_monitor, snooze_monitor, and delete_monitor by specifying that the monitor continues receiving pings.

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 implies the use case: pause a monitor when you want to stop alerts while still accepting pings. However, it does not explicitly state when not to use it or point to alternatives such as snooze_monitor or delete_monitor, leaving some routing to inference.

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