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

The description discloses important behavioral details beyond the annotations: it runs the exact same path as scheduled execution and includes history and dedup. This helps the agent understand side effects such as dedup counting and history recording, though it does not fully enumerate all possible downstream effects (e.g., notifications).

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—two sentences—and front-loads the core purpose. Every sentence adds useful information: immediate execution, same path as scheduled, and history/dedup behavior. No fluff or redundant wording.

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 description gives enough context to understand the tool's input and behavior. It does not describe the return value or error cases, but given the simple alert_id input and the absence of an output schema, the missing output details are not a significant gap.

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 only parameter, alert_id, is self-descriptive with its name and title, even though the schema does not provide a detailed description. The tool description does not elaborate on where to find the alert_id, but the parameter is straightforward enough given the sibling get_alerts tool.

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 verb 'Execute' and the object 'alert', with the specific purpose of immediate testing. It further clarifies that it runs the exact same path as scheduled execution, which distinguishes it from simple activation and makes its purpose unambiguous.

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 provides a clear use case: 'Execute an alert immediately to test it.' It does not explicitly name sibling tools as alternatives (e.g., activate_alert), but the mention of 'scheduled execution' and 'test it' strongly implies when this tool should be used versus merely enabling the alert.

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