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

Beyond the annotations, the description discloses two important behaviors: the tool may show a confirmation prompt when the client supports it, and otherwise it operates using the token's scope. It also confirms the non-read-only and idempotent nature, giving an agent a clear model of side effects and repeatability.

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?

Three compact sentences front-load the core purpose and then add only high-value behavioral notes. Every sentence earns its place, with no redundant elaboration.

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 an output schema and full parameter documentation, the description covers purpose, effect, confirmation behavior, auth scope, and idempotency. Nothing essential to invoking it correctly is missing.

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 sole id parameter is fully documented in the schema, including its provenance from list_monitors, so schema description coverage is 100%. The tool description adds no additional parameter-level meaning, so the baseline of 3 applies.

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 opens with a specific verb and resource: 'Pause a monitor', and immediately clarifies the effect with 'stop its checks until resumed.' This makes the tool's purpose unambiguous and distinguishes it from siblings like resume_monitor and run_check_now by defining the state transition it performs.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no alternative tools are named. The intended use is implied by the purpose, but the description does not mention resume_monitor as the counterpart or run_check_now as an alternative for immediate checks.

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