create_webhook

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

No annotations are provided, so the description carries the full burden. It discloses the core behavior (POSTs events) but omits important details like payload format, retry policy, idempotency, or the need for an HTTPS endpoint. For a creation tool, this is a moderate 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?

The description is very concise at two sentences with no redundancy. It front-loades the key action and allows further detail in the schema. However, it could be slightly more structured to separate the main action from the optional scoping.

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 no output schema and moderate complexity (5 params, 2 required), the description does not cover what the tool returns (e.g., webhook ID) or any lifecycle details. The schema descriptions compensate somewhat, but the description alone is incomplete for an agent to fully understand the tool's behavior.

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 minimal value by mentioning optional project scoping, which corresponds to the projectIds parameter. It does not elaborate on teamId or slug parameters, nor on the url format beyond the schema.

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 the tool creates a webhook that POSTs to an endpoint on chosen events, with optional project scoping. It specifies the action (create), resource (webhook), and behavior (POSTs events), making the purpose unambiguous.

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 lacks guidance on when to use this tool versus alternatives like create_log_drain. It doesn't mention prerequisites, authentication, or scenarios where a webhook is preferred over other notification methods.

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