Get one or more realistic sample webhook payloads for a specific event type, matching the envelope a live webhook delivery would produce. Used by integration platforms (Activepieces, n8n, Zapier) to show the payload shape before any real event fires. Falls back to synthetic data when no applicable entity exists in the account.

+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds genuinely new behavior: the synthetic-data fallback when no applicable entity exists in the account, which an agent cannot infer from structured fields. Limit defaults and version semantics remain undisclosed.
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?
Three sentences, front-loaded with the core action before the audience rationale and the fallback caveat. The integration-platform list is slightly indulgent but not wasteful; each sentence carries 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?
With no output schema, the description should carry more of the return-value burden; it says payloads match a live envelope but not the format, size, or how multiple samples are structured. The fallback note helps, but version/limit semantics and return shape leave gaps for a 3-parameter tool.
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% and the description compensates only partially: it clarifies that 'event' is an event type and that 'one or more' results are returned, implying the limit parameter. The 'limit' bounds (1-10) and especially the 'version' parameter (min/max 1) are left entirely unexplained in both schema and description.
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?
States a specific verb and resource ('Get sample webhook payloads for a specific event type') with the scope qualifier 'matching the envelope a live webhook delivery would produce.' No sibling tool does anything comparable, so it is trivially distinguishable from the list/queue/maintenance siblings.
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?
Gives a concrete usage context — integration platforms (Activepieces, n8n, Zapier) previewing payload shape before a real event fires — which tells the agent when this tool is the right call. It stops short of naming exclusions or an alternative to avoid, but the context is unambiguous.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
