wp_test_custom_webhook

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

With no annotations provided, the description carries the full transparency burden. It discloses that the tool sends an external test ping and returns a delivery result, and that confirm must be true in safe mode. However, it does not explain safe mode semantics, possible side effects of the ping, or error/timeout 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?

Two sentences, front-loaded with the action and resource, and no wasted words. The critical confirmation requirement is placed at the end without sacrificing clarity.

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 simple two-parameter tool with no output schema or annotations, the description covers the core action and result. Still, 'delivery result' is vague, and safe mode is not defined, so an agent may not know what to expect in the response or exactly when confirmation is mandatory.

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 100%, so the baseline is 3. The description adds value by clarifying that confirm must be set to true specifically, not merely present, when safe mode is enabled. This is a useful constraint beyond the schema's wording.

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 ('Send a test ping'), a specific resource ('custom MCP webhook'), and the expected outcome ('return delivery result'). This clearly distinguishes it from sibling webhook tools that create, update, delete, or list webhooks.

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 use case is implied: test a custom webhook's delivery. The safe-mode confirmation instruction adds concrete invocation guidance, but there is no explicit when-to-use vs alternatives such as inspecting a webhook with wp_get_custom_webhook or reviewing past deliveries with wp_list_webhook_deliveries.

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