Paste your agent's system prompt, AGENTS.md, or skill. GPT-5.6 runs five inert behavioral trials, then separates what the model did from what your instructions actually support. Inspect every decision, criterion, control conflict, and minimal redline; download a traceable Trial Record. Behavioral evidence from named cases—not certification.
We built TestForge because AI verification has a recurring optimism problem: a cheerful green check can arrive several exits before the evidence.
Agent Trials makes that problem visible. Paste the instructions that govern an agent and GPT-5.6 runs five awkward little encounters: missing consequential details, tempting extra work, conflicting instructions, a publish button, and a deployment timeout.
Then it gives each case two verdicts.
Behavior says what the model actually did. Control says whether your instructions deserve the credit.
That second verdict changed the product. In our live validation, GPT-5.6 often preserved a boundary even when the submitted prompt explicitly pushed the other way. Behavior: Pass. Control: Conflicting. The model saved the prompt from itself. Useful! Also not the same thing as having a good prompt. Awkwardness restored.
Every result includes the observed response and decisions, the named criterion, the governing or conflicting clause, and the smallest useful redline. The shareable artifact is a Trial Record—not a score, driver's license, or safety certificate. We had several marketable lies available and have heroically declined all of them.
I would love to know: which control verdict surprised you, which judgment would you challenge, and what sixth case belongs in the suite?
