Re:Show HN: Health billing agent denies claims in 1.2s, offi... by keertahacker on Thursday April 16, 2026 @01:01PM (#47796308)
A doctor friend asked me about billing agents their mixed experience not being able to dispute the agent due to abstractions. Wanted your thoughts. I feel agents should prove they are trustworthy and transparent to the human in the loop as in the end user, not the developer.

I built a tool where every AI agent action gets an Ed25519 signed receipt, hash-chained, and exported as a folder anyone can verify with openssl. No vendor software needed to verify.

The demo runs 20 simulated insurance claims sessions — standard agents and rogue agents. Every action is signed. Rogue actions are blocked and the blocks are signed too.

$ pip install agentmint && python -m agentmint.demo.healthcare

Cross-patient access: 10 attempts → 10 blocked Auto-deny (no review): 10 attempts → 10 blocked Prompt injection: 10 attempts → 10 caught before LLM

To run it: clone then cd agentmint-python/ Verify: cd healthcare_evidence && bash VERIFY.sh GitHub: https://github.com/aniketh-maddipati/agentmint-python/tree/m...

Also Would love to hear: Should verification require zero dependency on the vendor, or is that overkill?

Tear it apart, tell me what I can do to make it better. If you have thoughts on ways to make trust a currency for agents, comment below
