Changes confirmed high confidence

Salesforce ships Agent Script and a new Agent Builder, freezing the legacy builder

Agent definitions move from point-and-click configuration to versionable, testable code — a governance-relevant shift for enterprise SDLCs.

Salesforce released Agent Script — a code-first agent definition language — and a new Agent Builder in its July 1, 2026 wave, per the Salesforce developer blog. The legacy agent builder enters a freeze, with migration tooling and guidance for existing agents. Salesforce describes Agent Script as providing "deterministic control over agent reasoning" with versioning and testing hooks.

Context

Point-and-click agent builders democratized agent creation but produced artifacts that are hard to version, diff, test and audit. Moving agent definitions into code aligns agents with standard enterprise SDLC practice — code review, CI/CD, rollback — at the cost of narrowing who can author them. The shift lands the same week Salesforce made Agentforce Commerce generally available, signaling a platform-wide push from pilots to production discipline.

What changed

Why it matters

For enterprise governance teams, agent-as-code is a double win: agents become auditable artifacts with review trails, and changes become reversible. It also raises the skill bar for business teams that built agents in the legacy point-and-click builder — migration effort and retraining are the hidden costs of the freeze.

Details

Agent Script's stated differentiator is determinism — constraining agent reasoning paths rather than relying purely on prompt-level steering. Versioning and testing hooks let teams regression-test agents against defined behaviors before deployment, matching the governance direction of the wider market this month.

Limitations and caveats

Migration timelines and feature parity between legacy-builder agents and Agent Script were not detailed in the announcement; teams with large legacy agent inventories should pilot the migration tooling before committing. "Deterministic control" is a vendor claim about reduced, not eliminated, nondeterminism.
