create_mwindow

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

No annotations are supplied, so the description carries the full burden. It provides no behavioral details such as side effects, required permissions, idempotency, error behavior, or what constitutes a successful creation. The phrase 'Create a new maintenance window' merely restates the tool's name.

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 a single sentence with zero verbosity, achieving high efficiency. However, given the tool's complexity (5 parameters), it is arguably too terse to be fully 'appropriately sized', but it is concise and front-loaded.

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 an output schema, the description lacks important context such as return value semantics, prerequisites, or usage scenarios. A 5-parameter creation tool without annotations or behavioral guidance is not adequately described by a single clause.

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%, with each parameter having detailed descriptions (type, recurrence, start_time, etc.). The tool description itself adds no parameter information, but the schema already handles it, so a baseline of 3 is appropriate.

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 uses the specific verb 'Create' and resource 'maintenance window', clearly differentiating it from sibling tools like get_mwindows, edit_mwindow, and delete_mwindow. It unambiguously states the tool's primary function.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, use cases, or when not to use it, so the agent receives no contextual help in selecting between create/edit/delete/get tools.

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