If you’ve been building AI agents in the legacy Agentforce Builder, it’s time to plan your move.
The new Agentforce Builder is powered by Agent Script – a fundamentally better way to build, control, and test your agents. Here are five reasons to migrate your current agents to the new architecture.
1. Your agents will do what you tell them, every time
One of the biggest frustrations with AI agents is inconsistency. Because LLMs can interpret the same prompt differently across sessions, they often deliver varying answers to identical questions. Business-critical processes cannot be left to chance; they require certainty. This unpredictability quickly erodes user trust, which is why so many AI agents never make it past the pilot phase into production.
Agent Script solves this by combining deterministic logic with LLM reasoning – an approach Salesforce calls hybrid reasoning. Instead of relying entirely on natural-language prompts the model can misinterpret, you define structured rules the agent follows precisely. This ensures your agent consistently adheres to your business processes, eliminating unpredictable model behavior.
Fabienne Leroux, Lead Business Analyst Salesforce at Meilleurtaux — one of France’s largest loan and insurance brokers — sees Agent Script as the piece that makes AI usable in a heavily regulated industry.
“In the financial sector, an agent can’t just function: it must comply with every rule, every time,” said Leroux. “Agent Script gave us this control with real acceleration.”
The bottom line: Your agent follows your rules exactly, every time.
2. Faster agents, better experiences
Latency sours the agent experience. When an AI agent has to re-evaluate every topic and action on every single interaction, response times suffer. Users feel the lag, and your token costs climb.
Agent Script agents follow structured logic paths that skip unnecessary re-evaluation and get to the right answer faster. That means snappier responses for the person on the other end of the conversation, and lower token consumption for you.
Datasite rebuilt its service agent in the new builder and case deflection climbed from the low 60s to 82%.
The bottom line: Faster responses elevate the customer experience.
3. Debug your agent like a pro
Troubleshooting an AI agent often can sometimes feel like guessing. Session traces gave you limited diagnostics, and figuring out why an agent gave the wrong answer took time you didn’t have.
The new Agentforce Builder includes purpose-built debug traces so you can:
- See a full summary of your agent’s reasoning for every message
- Search the trace to find exactly where things went sideways
- Pinpoint the fix with both text and code views, right down to variable state changes
Ivaylo Enchev, Sr. Salesforce Admin at Nexo sees the payoff for his customer-facing agent, Nora.
“I’m so excited to have a bigger and massive overview on what Nora does,” Enchev said. “Every single conversation, every single topic, every unsuccessful conversation. What we saw in the tool would simplify so much of the stuff we’ve done.”
The bottom line: You can’t improve what you can’t see.
4. Anyone on your team can build agents
The legacy builder lives in Salesforce Setup, requires admin-level permissions, and has no built-in AI assistance. That bottlenecks agent-building to a small group of technical users.
The new builder is embedded in Agentforce Studio – a unified hub for building, testing, and monitoring agents. Business analysts can build agents in natural language on Canvas, without admin permissions. Developers can write directly in Script view, use VS Code or the CLI, and work with AI coding tools like Agentforce Vibes, Claude Code, and Cursor.
The bottom line: Your whole team can build agents, not just your most technical few.
5. Future-proof your agents – access what Salesforce is building next
Salesforce has frozen development on the legacy builder. As of July 2026, new agents can only be created in the new builder. And all future innovation is being built in the new builder with Agent Script, including:
If you want to expand use cases, scale to more complex workflows, and keep pace with AI innovation, the path is clear.
The bottom line: The future of Agentforce lives in the new Agentforce Builder.
What happens to my legacy agent?
One question you may have is, “What happens to my existing agent when I rebuild it in the new builder?” Activating your rebuilt agent in the new builder automatically deactivates the original. Once you’ve validated the new version, you can leave the legacy agent in place, archive it, or delete it — your call. See the Agentforce Migration Guide for details.
