Building Joule Agents in Joule Studio: Agent Builder, Skills, Grounding and Evaluations

Keep this: job aid

Joule agent build and release card

• Know your edition: classic (SAP Build lobby) or new Joule Studio (intent-based, managed runtime); check region and entitlements.
• Design canvas first: goal, users, inputs, tools, knowledge, boundaries, escalation, success.
• Agent prompt = description + Expertise + Instructions + Additional Context + tool descriptions; no conflicting rules.
• Toolset is the boundary: read freely, change only through confirmed processes, keep high-exposure actions out.
• Skills: action project → destination variable → Call Action → Condition → outputs/Send Message → Release → Deploy.
• Principal propagation for business data; positive and negative role tests; no raw API errors.
• Grounding register: one current version per topic, owner and effective date; nothing restricted or personal.
• Evaluation set: ~10 case types incl. injection, authorization and confirmation; frozen; run 3 times per release.
• Gate: controls 100%, accuracy threshold, escalation followed, cost per case within budget.
• Cost = conversations × steps × rate + headroom; watch steps per conversation as a regression metric.
