Create webhook

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is known. However, the description adds nothing beyond that: it does not mention the secret-handling constraint, the confirm requirement, the payload vs payload_file vs body-flags mutual exclusivity, or any side effects of registering a webhook.

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 sentence is short and front-loaded, but this is under-specification rather than conciseness. There is no wasted text because there is almost no text; it fails to earn its place by conveying any useful detail.

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 9-parameter mutation tool with deep nested JSON:API payloads, a secret field, and no output schema, a three-word description is completely inadequate. Nothing about authentication, required relationships, or payload construction is conveyed.

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 only 56% across 9 parameters, and the description supplies no parameter meaning at all. Critical semantics such as store_id, test_mode, and the payload/payload_file/account/confirm relationship are left entirely to the schema, which only partially documents them.

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?

"Creates a webhook" is a tautological restatement of the tool name and title, adding no distinguishing information. It does not clarify scope (per-store? per-account?), nor differentiate it from the siblings update_webhook, delete_webhook, or get_webhook.

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?

There is no guidance whatsoever about when to use this tool versus the related webhook tools, nor any stated prerequisites (e.g., needing a store ID, or the confirm flag requirement). The agent is left to infer everything.

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