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

Annotations already declare idempotentHint=true, openWorldHint=true, and destructiveHint=true, so the safety profile is largely covered. The description usefully adds what actually resumes (scheduled checks and alerting), but it never explains the destructive framing or any notification side effects, so the added context is modest.

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?

One sentence, front-loaded with the action and the object, with the outcome clause earning its place. There is no filler or redundancy.

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 state-toggle tool with full annotation coverage, the description covers what the tool does and its effect. The only meaningful gap is that it does not relate the tool to the pause/unmute/restore family, though annotations pick up the rest.

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?

There is a single required parameter whose schema coverage is 100% ('Monitor id.'), and the description adds nothing about it. Per the high-coverage rule, the schema carries parameter semantics and baseline 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 gives a specific verb ('Resume') and resource ('a paused monitor') plus the observable effect (checks and alerts restart on schedule). It does not, however, distinguish this from closely related siblings such as vs_monitors_unmute or vs_monitors_restore, leaving the agent to infer that those are different operations.

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?

Use is only implied by the phrase 'a paused monitor' – the agent must already know the monitor is paused and must infer that vs_monitors_pause is the inverse. There is no explicit statement of prerequisites or of when to choose unmute/restore instead.

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