wp_create_form_webhook

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states the bare action. It does not disclose whether the webhook is active by default, whether creating is idempotent or creates duplicates, what happens if the form_id doesn't exist, whether the URL is validated, or what side effects occur. For a mutation tool this is a significant transparency gap.

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?

A single sentence with no filler, front-loaded with the verb. It is efficiently written, though it earns its conciseness by sacrificing substantive content that other dimensions needed.

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 creation tool with 6 parameters, a nested headers object, no annotations, and no output schema, the description is too sparse. The agent is left without knowledge of the return value, default behaviors, or how this tool relates to the large cluster of sibling webhook tools (list/update/delete form, custom, WooCommerce).

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 only 50% — label, active, and headers have no schema descriptions. The description adds nothing about these undocumented parameters, nor does it clarify the relationship between form_id and the form targeted, or the behavior of the nested headers object. It fails to compensate for the coverage 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?

The description names a specific verb ('Create'), a specific resource ('Ninja Forms webhook action'), and a target ('on a form'), which clearly states what the tool does. The 'Ninja Forms' qualifier helps differentiate it from wp_create_custom_webhook and wp_create_woocommerce_webhook, though it does not explicitly name alternatives.

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 on when to use this tool versus siblings like wp_update_form_webhook, wp_delete_form_webhook, wp_list_form_webhooks, or the custom webhook tools. The agent must infer from the name alone that this is the create variant, with no context about prerequisites (e.g., form must exist) or scenarios where another webhook tool is more appropriate.

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