AG-X is the self-healing middleware that intercepts failures, applies autonomous vaccines, and ensures your production agents never repeat a costly error. One line of code. Zero changes to your agent.
Agents don't admit uncertainty. They pull from whatever's in their context — outdated pricing, deprecated policies, retired legal clauses — and act. By the time you notice, Step 6 is already done.
Stacktraces show what broke. They never show why the agent decided to do it. DoctorLLM reads the full chain-of-thought — not the output, the actual reasoning that led to the decision. You write a patch. You ship it. You hold your breath. That's not engineering. That's archaeology. Even the most advanced models drift, hallucinate, and get jailbroken.
A different input. A slightly different phrasing. Same catastrophic decision. The hard truth: when agents fail, they fail repeatedly — because they have no memory of their own mistakes. Prompt engineering is whack-a-mole. A vaccine is a permanent immune rule. One failure. One vaccine. Zero repeats. Across your entire fleet.
Point your SDK to the AG-X proxy or drop a single decorator on your agent function. That's it. No refactoring. No new infrastructure. We sit between your agent and reality — reading every call before any tool fires. Not the output. Not the log. The actual chain-of-thought.
Regex, JSON Schema, and forbidden strings — zero AI involvement, zero hallucinations. Every call is screened against every rule accumulated from past failures. Pattern matched → tool call cancelled. Your database never receives the query. The damage never happens.
DoctorLLM isolates the exact reasoning branch that triggered the failure and generates a vaccine — a compact, executable rule, not a vague prompt suggestion. It's backtested against 100+ historical runs before going live. Cannot be reasoned around, hallucinated past, or forgotten during a long context window.
One agent failed. Every agent in your fleet gets the vaccine before they ever encounter that situation. Your data agent, your SDR agent, your HR agent — one shared immune system. Network-effect security. The failure happened once. It will never happen twice.
Jump on a call directly with the founders. We walk through your stack, drop in two lines of code, and your first vaccine fires on the first real failure — same session. No docs. No handoff. No waiting.
