Test Alert Webhook

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

The description states the tool sends a test payload to verify delivery, which is consistent with the annotations (idempotentHint=true, destructiveHint=false). It adds context about verification without contradicting annotations. No additional behavioral details like auth or rate limits are provided, but annotations already cover safety.

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 that effectively communicates the tool's purpose. No filler or redundant information is present.

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?

Given the tool's simplicity, the description adequately explains the purpose. An output schema exists (not shown), so return values are covered elsewhere. Minor gaps exist, such as what the test payload contains or how verification is reported, but overall it's sufficient for a test tool.

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 4 parameters. The tool description does not add any additional meaning beyond the schema; it is a concise one-liner. With high schema coverage, baseline 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 clearly states the tool sends a test payload to a webhook URL to verify delivery before wiring it to an alert. The verb 'send test payload' and resource 'webhook URL' are specific, and the purpose is distinguished from sibling tools like create-alert which actually creates an alert.

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 mentions 'before wiring it to an alert', which implies the tool should be used to test webhook delivery prior to finalizing alert configuration. No explicit alternatives or exclusions are given, but the context is clear enough given the tool's specific purpose.

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