Built 3 AI agents scored AAA, Zach Wilson broke them on purpose, then I fixed them better than before. Shoutout to the DataExpert.io team for putting together something really practical. What I appreciate is how each agent type is separated as its own  selectable mode so you can see exactly what happens under the hood.             Knocked out 3 agent assignments back to back: 1. Context Overflow Agent - fixed a tool dumping 571K tokens per query down to  133 tokens (99.98% reduction) 2. Infinite Research Agent - tamed a runaway agent from $12/query crashes to $0.001 with a BudgetManager that tracks every token in real time        3. MCP Middleware Agent - built a keyword router that cuts 25 tools down to 6-11 per query, eliminating tool confusion                                On top of the agents I added:                         - 46 tests across all 3 agents, all passing, all hitting real APIs  - Langfuse wired in for full observability               - Per-step cost tracking with live dashboards  - Token usage and latency monitoring on every single LLM call  - BudgetManager class with graceful degradation when cost limits are hit  - No mocks, no shortcuts, production-grade testing                                            Every small and mid-size company should have this kind of AI agent platform  running in their business. The tools exist now, the barrier is just knowing  how to wire them together.                                            Code: https://lnkd.in/didukzk7  Tech stack:  Python + LangChain + Claude Sonnet + Langfuse + pytest + Claude Code                                            So excited building AI agents. 2026 is the year of agents - not just chatbots that talk, but agents that actually do things, track their own costs, and know when to stop.  #AIAgents #LangChain #Langfuse #AIEngineering #BuildInPublic
