Create webhook

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

Annotations already declare this is not read-only and not destructive, and the description's 'Create' aligns with that. The description adds a behavioral detail about immediately subscribing via event codes, but does not disclose other traits like default enabled state or response behavior.

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 with no wasted words. It states the core action and the optional subscription capability concisely.

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 no output schema and five parameters, the description could be more complete regarding expected response or side effects. However, the schema describes most parameters, and the tool's CRUD context is evident from sibling names. The description provides a viable baseline for invocation but lacks deeper behavioral details.

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 80% with most parameters described. The description adds value by clarifying that 'subscriptions' can be event codes for immediate subscription, which is not fully specified in the schema. It does not cover the 'name' parameter, but the schema's high coverage compensates.

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 states 'Create a webhook endpoint' with a specific verb and resource, clearly distinguishing this from sibling tools like update_webhook, delete_webhook, and list_webhooks. It also adds a useful option about subscription event codes.

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 a clear use case (creating a new webhook) and mentions optional subscriptions, giving context for when to pass subscription codes. It does not explicitly compare with alternatives, but the tool name and sibling list make the usage obvious.

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