When Your AI Agent Is Just an Overpriced Cron Job

Today I reviewed a client's case: automating weekly API reports. The task: extract data, transform it, send to Slack. Textbook use for n8n or a simple Python script.

But the client insisted on a "full-fledged agent." The result:

• LangChain orchestrator
• Two GPT-4 calls to "analyze" template data
• A bill 3x higher than necessary

• This reminded me of Vertu Alphafold—where complexity becomes a feature. But in business, you pay per token.

  Where's the Actual Value Add?

  Comparing two approaches for the same task:

  1. Classic ETL: 12 lines of code, $0.002 per run
  3. "Agent": 3 services, $0.7 per report + latency

  4. A 350x cost difference for identical output. Yet the client is thrilled—they now have "AI-powered analytics."

     Automation ≠ agency. Sometimes you just need working glue code.
