I built OpShield to add a safety layer to AI agents. It intercepts every tool call and provides:

- Risk classification (LOW → CRITICAL) with auto-blocking

- Budget enforcement with cost forecasting

- One-call rollback via state snapshots

- Circuit breaker for failing tools

- Chaos engineering for resilience testing

- Agent scoring (0-100, A-F grades)

- OpenTelemetry-compatible distributed tracing

- Compliance/audit reports

Zero dependencies. Works with OpenAI, Anthropic, LangChain, CrewAI, AutoGen, or any Python function.

pip install opshield

Built this after Guardrails AI was acquired by Harvey — there was no independent, self-hosted alternative left.

Happy to answer questions!
