Frequently asked questions

What is Agent builders?

Platforms for designing, testing and publishing agents rather than a single prebuilt agent product. Jobs: agent design canvases; tool registration; eval and publish of custom agents.

What should not be listed as Agent builders?

Products whose buyer job is a finished agent SKU, orchestration fabric, or generic low-code app builders. Those belong on their own category page so search queries are not split.

Has AI Trustmark independently assessed every Agent builders supplier?

No. A category listing is descriptive. Independent assessment is shown only on company or product pages that carry Trustmark evidence.

What are Agent builders?

Platforms for designing, testing and publishing agents rather than a single prebuilt agent product. Jobs: agent design canvases; tool registration; eval and publish of custom agents.

What should buyers check when an AI agent can take actions?

Ask which tools, systems and write actions are allowed, whether those actions require human approval, and how they can be stopped. Category membership as an AI agent is a topic label, not permission to act in a buyer environment.

How is an AI agent different from workflow automation?

Workflow automation follows a designed path, even if a model fills a step. Agents choose steps toward a goal. Both can write to systems; the control model differs. Do not treat an RPA bot or a predefined workflow as an open-ended agent in procurement language.

Should agent actions require human approval?

Human approval is a control, not a default. Buyers should specify which action classes need approval, who can grant it, and whether the agent can proceed unattended after a session starts. Independent assessment records the approval model that was evidenced.

What evidence should buyers request from an AI-agent supplier?

Request the named product, permitted actions, logging, approval model, independent assessment depth if any, and the live certificate record rather than a badge image. Supplier-stated answers are not the same as documented, demonstrated or independently verified evidence.
