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

Annotations already cover idempotency and non-destructiveness. The description adds meaningful state-lifecycle detail beyond annotations: the pause persists until an explicit resume or a ping re-activates it. This helps the agent predict side effects without contradicting the idempotentHint.

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 one efficient sentence that front-loads the action and resource, then adds the key lifecycle behavior. Every phrase earns its place with no redundancy or 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 one-parameter, non-destructive, idempotent tool with no output schema, this description is complete. It covers what the tool does, the effect on alerting, and how the paused state ends, which is everything an agent needs 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 coverage is 100% and the single required parameter 'id' is described as 'Monitor id.' The description adds no additional parameter guidance, but the baseline 3 applies because the schema already documents the only parameter sufficiently.

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 and resource: 'Pause a monitor so it stops alerting.' It also clarifies the behavioral scope with 'until resumed or pinged again,' which implicitly distinguishes this from siblings like resume_monitor and create_monitor. An agent can identify what this tool does and what it does not do.

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 usage: use this when a monitor should stop alerting temporarily. The phrase 'until resumed or pinged again' gives lifecycle context, but it does not explicitly name alternatives or state when not to use this tool. Guidance is adequate but left to inference.

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