i̲m iAgentSim
Part of the iJarvis Agent Stack

Stress-test your agent before deploy.
Adversarial counterparties, prompt injection fuzzing, goal-drift scenarios.

iAgentSim will be the sandbox environment for testing agent behavior under adversarial conditions before deployment. Synthetic counterparty agents that attempt prompt injection, byzantine actors, resource pressure, and goal-drift scenarios. Cluster 3 roadmap 2028.

iagentsim.run(agent, scenarios=['injection', 'byzantine_counterparty', 'budget_pressure'])

iAgentSim will provide four primitives

Adversarial counterparties

Pre-built red-team agents that attempt prompt injection, output manipulation, and context poisoning. Fuzz your agent before real attackers do.

Scenario library

Budget pressure (force your agent to overspend), byzantine oracle (poisoned input data), goal drift (gradual prompt shift), social engineering simulations.

Regression tracking

Run the same scenario suite after every prompt change or model upgrade. Catch behavioral regressions.

Replay + fork

Replay real iAgentLog traces. Fork at any decision point and ask 'what if the counterparty had been malicious?'

The gap iAgentSim fills

You cannot catch adversarial behavior in unit tests

Traditional testing gives known inputs and checks outputs. Adversarial testing injects behaviors that real-world attackers will try, which unit tests never imagine.

LLM eval ≠ agent eval

LangSmith datasets, Braintrust evals are great for LLM output quality. Bad for adversarial agent-to-agent interaction testing.

Integrates with iAgentLog and iAgentSafe

Pull real behavior baselines from iAgentLog, validate iAgentSafe policies actually fire in adversarial scenarios.

Planned endpoints in Roadmap 2028 (Cluster 3)

iAgentSim is one layer

Sixteen products. One stack. One entity. Trust, discovery, observability, payments, safety, simulation, composition, memory, identity, legal, markets, and owned compute underneath. Each layer reinforces the others. Use one or use them all.
