The original title is "Operable Over Sophisticated: What Shipping AI Agents at Scale Actually Looks Like"

Short summary

Teams shipping AI agents at scale consistently find that operability beats sophistication. Rippling's production experience yielded four principles: keep agents flat for debuggability, build generic composable tools, pass code schemas into LLM context instead of raw data, and use governed SQL for structured retrieval. Lyft's eval session reinforced that single-run eval scores are samples from a distribution, not measurements — shipping on one run is insufficient.

• •Flat agent architectures outperform hierarchical sub-agents in production due to debuggability
• •Generic composable tools and governed SQL interfaces scale better than task-specific bespoke tools
• •Agent eval scores are non-deterministic; single-run results are samples, not measurements
