Polarity is a sandboxed eval infrastructure for AI agents, providing isolated Docker environments with real backing services like Postgres and Redis. It scores agent behavior against invariants, detects non-determinism, and reproduces failures locally, ensuring accuracy for complex, multi-step agents.

How to use Polarity?
Use Polarity to test AI agents in production-like sandboxes before deployment. Define behavioral invariants, run evals, and get seed reproducers for failures. It catches issues like slow tool responses, hallucinated SKUs, or missed escalations, helping teams debug and optimize agent decision-making at scale.
Polarity 's Core Features
Sandboxed eval runtime: Runs each agent task in isolated Docker sandboxes preloaded with real services like Postgres, Redis, and S3, ensuring accurate testing.
Behavioral scoring: Scores agent runs against invariants and forbidden rules, measuring non-determinism via replicas for reliable results.
Seed reproducer: Ships every failure with a seed that recreates the identical sandbox locally with one command, simplifying debugging.
Production-like environments: Uses real backing services instead of mocked dependencies, catching stateful failures that prompt-level tools miss.
Automated monitoring: Tracks agent and user behaviors, surfaces regressions, and alerts teams to issues like model drift or missed escalations.
Triage with AI swarms: Deploys agent swarms to find similar failure cases, analyze impacted use cases, and narrow root causes.
Integration with Slack: Allows teams to investigate agent failures directly in Slack, with real-time responses and analysis.
Polarity 's Use Cases
AI developers: Test complex multi-step agents in sandboxes with real services to catch stateful failures before production deployment.
DevOps engineers: Debug agent failures with seed reproducers that recreate exact sandbox environments locally for quick fixes.
Product managers: Monitor agent decision-making and surface regressions like missed escalations or hallucinated data.
QA teams: Run behavioral evals against invariants to ensure agents follow rules and avoid forbidden actions.
Enterprise teams: Ensure compliance with SOC 2, GDPR, and HIPAA while deploying agents at scale with custom sandboxes.
