HubSpot agent tool config describes the run you can prove
Write the agent tool's type, action description, inputs, and outputs as a contract you can demonstrate on every successful run.
Why this can grow a startup
The weakest agent listings treat configuration as metadata and the actual run as a separate concern. HubSpot treats them as one thing. `toolType` has to match the operation, `llmConfig.actionDescription` has to follow description guidance, and every configured output has to be returned in the promised format. That forces the product page, tool schema, and live behavior to agree. When they agree, the review process is faster and the buyer sees a workflow instead of a prompt-shaped guess.
Company example
HubSpot says `GET_DATA`, `GENERATE`, and `TAKE_ACTION` should match the real job of the tool, and if the output config includes a `success_message` string the tool should return that property in the expected format on every run.

Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
