create_webhook

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

No annotations are provided, so the description must disclose behavior. It states the basic function but omits critical details like idempotency, side effects, authorization, or rate limits. The parameter 'webhook_data' is left entirely to external docs.

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 short (two lines) but includes 'Args:' which adds minor structure. It could be more concise by integrating the parameter info into the main sentence. However, the brevity is acceptable, though underspecified.

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?

With a complex parameter (object with additionalProperties), no output schema, and no annotations, the description is severely incomplete. It fails to explain how to structure the webhook_data, what events are available, or what the response looks like.

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 coverage is 0%, yet the description adds no meaningful information about the 'webhook_data' parameter. It merely repeats 'webhook data' and defers to external docs, failing to compensate for the schema's lack of description.

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 action (Register) and the resource (webhook URL for a specific store and events). It distinguishes from sibling tools like list_webhooks (listing) and create_checkout (different resource).

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?

No guidance on when to use this tool versus alternatives. The description references 'see LemonSqueezy API docs' but does not provide concrete usage context or exclusions.

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