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

With no annotations provided, the description discloses the key behavioral effect: alerts and notifications are suppressed during maintenance. It also mentions support for one-time and recurring windows, adding useful context beyond the basic create operation.

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 concise at two sentences, front-loaded with the main action, and contains no redundant or vague phrasing. Every word contributes to understanding the tool's purpose and effect.

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?

Despite having 7 parameters and no output schema, the description only covers the basic purpose and suppression behavior. It does not explain how to configure recurrence (the isRecurring and recurrence relationship) or mention what the tool returns, leaving the agent to infer these details from the schema.

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 input schema has 100% coverage with descriptions for all parameters, so the baseline is 3. The description adds minimal parameter information beyond the schema, only hinting at daily/weekly recurrence without explaining the isRecurring/recurrence dependency.

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 clearly states the action with a specific verb ('Schedule') and resource ('maintenance window for a target'), and explains the core purpose (suppress alerts/notifications). It distinguishes from sibling tools like list_maintenance_windows and delete_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 implies usage context by mentioning alert suppression during maintenance, but it does not explicitly state when to use this tool versus alternatives like create_muting_rule or create_automation_rule, nor does it provide exclusion criteria.

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