How Salesforce Standardizes Agent Evals with LangSmith
LangChain
The Signal
Salesforce’s Agentforce team has adopted LangSmith to standardize quality control for its enterprise coding agents. As the internal volume of generated code has surged to over 100 million lines, the team moved away from fragmented, team-specific validation tools to a centralized evaluation framework. The core tension lies in maintaining reliable code quality at extreme scale.
The Case
The Shift to Centralization
- Before adopting LangSmith — the evaluation and testing platform for AI agents — Salesforce teams built their own custom MCP tools to generate components and metadata, leaving each group to independently figure out how to validate their outputs.
- The team now uses LangSmith to inspect execution traces and diagnose unexpected behavior before any code reaches customers, replacing the previous reliance on ad hoc, team-by-team validation.
Scale and Standardized Metrics
- To manage the scale required by Agentforce 5 — the latest iteration of the enterprise 'vibe coding' product launched in October 2025 — the company runs thousands of test cases through a shared scoring layer.
- Teams evaluate outputs against four named performance dimensions: instruction following, coherence, factuality, and deployability.
- The team credits this standardized evaluation with enabling them to pass a milestone of over 100 million lines of accepted code, though the causal link between this testing framework and overall product reliability is asserted by the company rather than verified by external data.
The 1 Minute Signal Take
While the move toward centralized evaluation is a logical step for managing large-scale code generation, the internal claim that this tool ensures quality remains a corporate assertion. The real takeaway is the industry-wide shift toward treating agentic code production with the same rigorous, trace-based testing standards previously reserved for traditional software engineering.
