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

Annotations already record idempotentHint=true, destructiveHint=false, and readOnlyHint=false. The description adds behavioral context by explicitly stating the operational effect ('no checks run and no alerts fire') and the underlying equivalence to update_monitor with paused=true, which goes beyond the structured fields.

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 entire description is one front-loaded sentence that immediately states the action, adds two concrete behavioral consequences, and gives the equivalent API. Every clause earns its place with no filler.

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 single-parameter, idempotent mutation with rich annotations and no output schema, the description covers what the action does, what it stops, and how it relates to the update_monitor sibling. Nothing essential is missing for an agent to invoke it correctly.

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 only parameter, uuid, is already described as 'UUID of the monitor to pause.' The tool description does not add parameter-specific detail, so the schema carries the semantic weight; baseline 3 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?

The description states a specific action ('Pause a monitor') and clarifies the exact behavioral scope by saying no checks run and no alerts fire. It also situates itself relative to update_monitor with paused=true, which makes the tool's identity unmistakable.

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 a clear usage context: use this tool when the goal is to pause a monitor so checks and alerts stop. It references update_monitor as the equivalent general alternative, but it does not explicitly mention when-not-to-use or the resume_monitor sibling.

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