What's the best way to build reliable AI agents in 2026?
I've been exploring AI agents and how to make them useful for real-world applications, especially in the Web3 ecosystem.
One thing I'm curious about is how other developers approach building reliable AI agents beyond simple demos.
A few questions for the community:
- Which frameworks are you using to build AI agents?
- How do you handle tool calling, memory, and multi-step tasks?
- What has worked best for making agents more reliable in production?
I'm particularly interested in practical experiences rather than just theoretical approaches.
Would love to hear what you're building and what's working for you! 🚀

What helps most in the agent setups I build: keep each step small, check tool output against a schema or a test instead of trusting the model, and put a human checkpoint before anything you can't undo (sending, paying, deleting). The framework has mattered a lot less than that for me.
Onchain adds a reliability problem most agent stacks never face: state you can't roll back, plus RPC data that goes stale or reorgs mid-task. Are you replaying failed runs against forked chain state to test agents, or relying on testnet runs before shipping?
Practical notes from running a paper-trading agent on live market data: 1) The model only proposes; code decides. It asks for a share of equity, code turns that into whole shares and refuses anything past the caps, and no model is asked anything at execution time. 2) Every refusal carries a named reason in a decision log (a cap, the cooldown, low confidence), so failures are debuggable instead of mysterious. 3) Split refusals that are final (leverage, already held) from ones that are only "not now" (cash, cooldown), or the agent keeps retrying things that can never pass. 4) Derive each order's idempotency key from what it executes, not from the tick, so a step that dies after the fill can't fill twice on retry. That last one matters even more onchain, where you can't roll back. Framework choice mattered far less than these. How we apply it to market risk: hpsilab.com/ — Haiyun
