simulate_stripe_event

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

With no annotations present, the description carries the behavioral burden. It discloses the key side effect: building and sending the event to a webhook, and adds important detail that the event is signed with Stripe-Signature. It also clarifies that app overrides set_app for this call only, giving useful scoping behavior beyond the raw schema.

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 two concise sentences with no wasted words. The main action and signing behavior are front-loaded, and the app parameter note is direct and relevant. It is appropriately sized for the tool's complexity.

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?

The description leaves significant gaps: it does not explain what event_type values look like or are accepted, what overrides can contain, what the resulting behavior/return value is, or what happens if no app or registered webhook exists. Given no output schema and no annotations, more context is needed for an agent to invoke this tool with confidence.

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 0%, so the description must compensate. It explains only the app parameter and its override behavior. The required event_type is not described, and overrides is an unconstrained object with no explanation of its purpose or allowed keys. This is insufficient for an agent to reliably construct a correct call.

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 states a specific action ('Build and send') and resource: a simulated Stripe event, signed with Stripe-Signature, sent to a registered webhook. This clearly differentiates it from sibling simulation tools like simulate_github_event or simulate_facebook_event by naming Stripe and the webhook target.

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 intended use is implied: simulate a Stripe webhook event to test the registered webhook. The app override is explained. However, there is no explicit guidance about when to prefer this tool over sibling simulators, nor any stated prerequisites such as needing a webhook registered first.

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