Building AI Agents: Lessons Learned over the past Year

Building production AI agents proved far harder than early prototypes suggested; agents initially struggled to generalize to all real-world scenarios across disparate data sources and businesses.

How it works
Common implementation structure
How this type of workflow is generally built, generalized across documented cases — not tied to any one vendor's stack. Click any stage to read what happens there. Specific products that implement these stages appear in “Tools commonly seen” below.
Stage 1 · User submits objective
A conversation starts with an objective and an agent system prompt.

Outcome

After extensive iteration, the team achieved a baseline of stability and performance across disparate data sources and businesses, with Fortune 500 users relying on the agent daily for data analysis.

What failed first

Agents on weaker models hallucinated table names instead of searching for real ones; agents silently ignored columns listed in tool-call responses due to markdown formatting; fine-tuned models degraded reasoning by causing agents to short-cut their directions.
