Create Webhook

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

With no annotations, the description carries the full burden, and it does add real behavioral context beyond the schema: the SSRF validation step, which implies a possible failure mode on URL submission. It stops short of covering permissions/scope required, what happens on duplicate name, or whether a signing secret is generated and returned — meaningful gaps for a mutation tool with zero annotation coverage.

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 short sentences, zero filler, with the hard constraint (HTTPS + SSRF validation) front-loaded right after the purpose. Nothing could be removed without losing information.

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 mutation tool with no annotations and no output schema, the description covers purpose and one validation constraint but omits the response shape (e.g., whether a webhook ID or signing secret is returned), permission requirements, and duplicate-name behavior. Adequate to invoke, insufficient to predict the result.

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 description coverage is 100%, so all five parameters are already documented in the schema (including the events/all_events interaction and defaults). The description only echoes the HTTPS constraint on url, adding nothing new about parameters; baseline 3 applies.

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?

Specific verb + resource: 'Create a new webhook in your workspace' leaves no ambiguity about the operation or the object. It does not, however, distinguish itself from siblings like update-webhook or create-domain beyond the name itself, so no sibling routing context is added.

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 offers no when-to-use, when-not-to-use, or alternative guidance — nothing tells an agent whether to call this instead of update-webhook for an existing endpoint, or what prerequisites exist (e.g., whether events must already be known). Usage is only implied by the tool name.

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