rm_create_webhook

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

Annotations already convey that this is a non-read-only, non-destructive operation, and the description aligns with that. However, the description adds little behavioral context beyond the word 'Register'—it does not explain side effects, delivery behavior, or any constraints on the webhook subscription.

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 sentence with no wasted words, front-loading the core action and resource while using examples to clarify the event_type parameter.

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?

The tool is relatively simple, has an output schema, and annotations cover the safety profile. However, the description omits guidance on callback URL requirements and the full range of valid event types, so an agent may need to rely on assumptions or external knowledge to invoke it correctly.

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?

With 0% schema description coverage, the description must compensate for the parameters. It provides example values for event_type, which is helpful, and the parameter name callback_url is fairly self-explanatory in the context of a webhook subscription. Still, callback_url semantics are not explicitly described, leaving a gap.

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?

States the specific action 'Register' and resource 'webhook subscription', with concrete event-type examples. This clearly distinguishes it from sibling tools like rm_list_webhooks and rm_delete_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?

Does not explicitly state when to use this tool rather than alternatives or any prerequisites. The verb 'Register' implies a creation scenario, but no guidance is given about event type validity, callback URL requirements, or cases where listing/deleting webhooks would be more appropriate.

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