get_webhook_event

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

No annotations are provided, so the description carries the full burden. It discloses the returned data (payload, snapshot, response, retry schedule) but does not mention behavior details like error handling, required permissions, or idempotency. For a simple read operation, the description is adequate but not rich.

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 two sentences with zero waste: the first states the action and returns, the second provides a clear usage case. It is efficiently 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?

For a single-parameter fetch tool without output schema, the description lists all expected return components (payload, snapshot, response, retry schedule). The sibling context (list and retry) supports its role. Some missing context like pagination or error states, but overall complete enough.

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% (only one parameter 'id' with description). The description adds minimal value beyond 'by numeric id,' not elaborating on the id's meaning or format. Baseline 3 is appropriate as the schema already documents the parameter sufficiently.

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 starts with 'Fetch one webhook event by numeric id,' providing a specific verb and resource. It further details the return values (full payload, endpoint snapshot, response status/body, retry schedule), clearly distinguishing it from sibling tools like list_webhook_events (list) and retry_webhook_event (retry).

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 ends with 'Use this to drill into why a delivery is failing,' explicitly stating when to use the tool (investigating delivery failures). However, it does not mention when not to use it or explicitly compare to alternatives, though the sibling list suggests retry_webhook_event as a follow-up.

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