Service to Monitor True AI Agent Execution Results

The author developed Witnessed to catch a common failure mode for AI agents in production:
- The agent appears to execute successfully internally
- But the real-world effect never actually happens
- With no errors or logs, the agent proceeds to make decisions based on false assumptions
The core idea is to treat this like an "accounting problem": comparing states before and after an action to independently verify if the result truly occurred. The author has built this concept into a small service, which is now live and offers a free tier.
