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

Annotations already flag destructive/not-idempotent/write, but the description adds real behavioral detail beyond them: checks are disabled then re-enabled, no alerts fire during the window, and the window is created inactive unless start_now=true starts it immediately. This lifecycle disclosure is exactly what an agent needs for a write tool.

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?

Front-loaded WRITE marker, then the effect and the inactive/start_now nuance, then the endpoint. Three compact sentences 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 no-output-schema write tool whose annotations carry the safety profile, the description covers lifecycle, effect and start behavior well. Minor gaps remain around auth/sub-account requirements and any rate or conflict behavior, but nothing an agent must know to invoke it 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?

Schema coverage is moderate (60%) and the schema already documents start_now's default and duration_minutes' max. The description reinforces duration_minutes and start_now semantics but adds little beyond the schema, and does not touch name or customer_id.

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?

States a specific verb (create) and resource (one-off maintenance window) plus the effect: disables the listed checks for duration_minutes and re-enables them afterwards. This clearly distinguishes it from sibling maintenance tools like get/list/delete_maintenance.

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 clear context (one-off maintenance that suppresses alerts), which implicitly differentiates it from recurring schedules or mute_check, but it never names an alternative or an exclusion condition explicitly. Clear context without explicit when-not guidance.

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