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

Annotations only mark the operation as non-read-only and non-destructive. The description adds meaningful behavioral facts: checks and alerts are suspended during the window, selected status pages announce it, and the window is public once status pages are attached. This is valuable context beyond the annotations and with no contradiction.

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 two compact sentences with no filler. It front-loads the core action and effect, then states the important privacy/consent caveat in the second sentence. Every sentence earns its place.

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?

With 10 parameters, the schema fully documents field semantics, and the description supplies the behavioral and consent context that schema cannot convey. The description does not mention return values or error cases, but with no output schema this is a minor gap rather than a critical omission.

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%, so the baseline is 3. The description adds extra meaning by connecting the monitors parameter to 'checks and alerts stop' and the status_pages parameter to 'announce it'/'public', which clarifies the real-world consequences of those parameters beyond their schema definitions.

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 ('Schedule') on a maintenance-window resource and explains the concrete effect: checks and alerts stop for the named monitors, and passed status pages announce the window. This distinguishes it from maintenance-window lifecycle siblings like update_maintenance_window or cancel_maintenance_window.

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 gives one important precondition: 'confirm with the user first' if status pages are passed, because the window becomes public. However, it does not explicitly explain when to choose this tool over alternatives such as update_maintenance_window, cancel_maintenance_window, or complete_maintenance_window; that choice is left mostly to inference.

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