Agent Script and the New Agentforce Builder

Agentforce & AIAgent Script and the New Agentforce BuilderMake agents predictable with hybrid reasoning: learn the Agent Script language (blocks, variables, subagents, logic and prompt instructions, actions, conditions, transitions and lifecycle hooks), build a complete order-support agent with deterministic identity verification, and manage .agent files with Agentforce DX.Advanced · about 90 minutesWhat you will learn

Explain why pure LLM reasoning is non-deterministic and how hybrid reasoning addresses it

Navigate the new Agentforce Builder and relate it to the underlying Agent Script

Read and write Agent Script blocks: config, system, variables, language, connection, start_agent, subagent, actions, reasoning and after_reasoning

Combine logic instructions (->) and prompt instructions (|) with variables, run, set, if/else and transitions

Gate actions and transitions with available when conditions and bind inputs deterministically

Create, validate, preview and publish authoring bundles with the Salesforce CLI
