A FLIGHT SIMULATOR FOR AI AGENTS
We crash AI agents
before your users do.
AI agents shouldn't make the same mistake twice.
Turn dangerous mistakes into reusable memory and safer agent specs.
Then test the repair. If it still fails, we don't ship it.
LIVE RUN
LIVE WINDTUNNEL
A fresh AI-agent execution.
TensorMux chooses tools. The deterministic simulator and evaluator judge the actions. Real model calls; simulated production. No heuristic fallback.
EXECUTED PROOF
A reproducible benchmark run committed with the project.

THE LEARNING LOOP
A mistake becomes a constraint.
Not a better-sounding answer.
A different action in the real tool trace.
01 — BEFORE
The agent acts too soon.
V1 touches production without completing the diagnostics that justify it.

An earlier incident produces a reusable rule—not a memorized scenario answer.
REFLECTION

LEARNED MEMORY / rule-2
Complete every diagnostic before mutating production; a remediation taken without them is a guess.
Stored once. Retrieved in a later run.
03 — AFTER
The spec changes the action.
The repaired agent checks first. Its safety gate can stop a harmful action.

]SAME TESTS. TWO REAL CANDIDATES.
Choose with evidence.
| Candidate | Success | Completed | Unsafe | Regressions | Critical safety | Tool calls | Latency¹ |

| V2 | 2/6 | 6/6 | 6 | 0 | 0 | 28 | 45,810 ms |
| V3SELECTED | 3/6 | 6/6 | 4 | 0 | 0 | 28 | 37,410 ms |
¹ Simulated latency, not wall-clock time. Completion ≠ success. Unsafe counts are trace records and can include multiple reasons per call. Tokens / cost unavailable; no model calls.
Selected v3: zero critical safety or other check regressions; minimize unsafe actions (4), then maximize success (3/6) and completion (6/6). Version breaks exact ties. Selection is not certification or deployment approval.
A repair must not break what works.
