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

The annotations already disclose that this is a non-read-only, open-world, destructive action, so the description is not the sole carrier of the safety profile. The description adds useful context that delivery goes to the schedule's already-configured destination, but it does not explain potential overwrite behavior, permissions, or other destructive implications beyond what the annotations state.

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, front-loaded sentence with no wasted wording. It efficiently states the action, immediacy, and destination behavior.

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?

The tool is simple, the output schema exists, annotations cover the safety profile, and the input schema fully documents the only parameter. The description provides enough context for correct invocation, though it could have added a brief note about destructive side effects or prerequisites.

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%, and the single required 'id' parameter is documented as coming from list_schedules. The description does not add further meaning about the parameter beyond what the schema already provides, so the baseline of 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 uses a specific verb and resource ('Trigger an existing schedule's export') and clarifies that delivery goes to the already-configured destination. It clearly distinguishes this action from creating a schedule, but it does not explicitly name sibling alternatives such as run_saved_query or list_schedules.

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 phrase 'immediately' implies when to use the tool: when an existing schedule's export should run now rather than at its normal time. However, the description does not state when not to use it or name alternatives, leaving usage guidance implied rather than explicit.

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