webhooks_test

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It does disclose that the delivery is recorded in history and that it's synchronous with immediate outcome return. However, it doesn't state whether a successful response is required, what happens on failure, or any permission/authorization requirements. For a tool performing an outbound network action, additional transparency about side effects would strengthen this.

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?

Three tightly-worded sentences with zero wasted content. Front-loads the primary action, then adds the payload characteristic, then prerequisite and side-effect. Every sentence earns its place with concrete information.

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?

For a test/diagnostic tool with no output schema, the description could explain what the returned outcome looks like, how to interpret success vs failure, and how it relates to delivery history. The requirement that the webhook must be active is mentioned, which is useful, but without annotations or an output schema, more detail on the return value semantics would improve completeness for a tool that's explicitly about returning an outcome.

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%, so the schema already documents all three parameters. The description adds the context that eventType overrides the default webhook.test and that companyId overrides an env var, which adds some meaning beyond the schema. However, the description doesn't explain how to determine a valid webhook endpoint UUID or the relationship between companyId and the uuid parameter.

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 it sends a synchronous test delivery to a webhook endpoint and returns the outcome, specifying it uses a synthetic webhook.test event payload. It's specific about verb (send), resource (webhook endpoint), and behavior (returns outcome immediately). However, it doesn't explicitly distinguish from sibling tools like webhooks_deliveries or webhooks_delivery_detail, though the 'synchronous test' nature inherently separates it.

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 when to use it (to test a webhook endpoint before or during setup) but doesn't explicitly state when NOT to use it or mention alternatives like webhooks_deliveries for viewing past delivery history. The requirement that 'the webhook must be active' provides some usage context but there's no exclusion guidance against sibling tools.

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