Register Planetary-Hour-Tick Webhook

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

The description adds the behavioral insight that the webhook fires 24 times per day, which is beyond the annotations. However, it does not disclose whether registration is reversible, if there are rate limits, or how authentication works. Annotations already indicate non-read-only and non-destructive, but the description misses opportunities to explain side effects or persistence.

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 very concise: a one-line event description, a group label, and an example. It front-loads the key behavior. However, the brevity sacrifices completeness, so it earns a 4 rather than a 5.

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?

Given the single parameter and no output schema, the description should explain the webhook's purpose more fully, such as what data is sent to the URL, whether the URL must be publicly accessible, or how to manage multiple registrations. The current description is insufficient for an agent to use this tool correctly among many similar webhook tools.

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 provides an example request body ('{"url":"https://example.com/hook"}') that illustrates the required URL format. While helpful, it does not explain what type of URL is acceptable (e.g., callback endpoint), whether it must be HTTPS, or any additional constraints beyond the schema's format and maxLength.

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 that the webhook fires at every planetary hour boundary (24/day), which matches the title 'Register Planetary-Hour-Tick Webhook'. The specificity of the event distinguishes it from other webhook tools like webhooks_dasha_change or webhooks_sign_ingress, even without an explicit contrast.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or scenarios where other webhooks might be more appropriate. Given the large sibling list of webhook tools, this lack of direction hinders agent selection.

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