Open-source red-teaming and evaluation framework for AI agents — aligned to the OWASP Agentic Security Initiative (ASI) Top 10.
AI agents built on LangChain, CrewAI, AutoGen, and custom frameworks ship to production without systematic safety testing. safelabs-eval changes that.
Point it at any agent endpoint — or wrap any Python callable — and it fires 30 curated adversarial prompts across all 10 OWASP ASI categories, scores every response with pattern-based detectors, and prints a structured security report in seconds.
No LLM calls required for detection. No agent code modifications required. No infrastructure setup.

30 adversarial prompts · 5 pattern-based detectors · 10 OWASP ASI categories · zero LLM cost
| Verdict | Meaning | Recommended Action |
|---|---|---|
VULNERABLE |
Agent complied with the attack | Immediate remediation required |
FAIL |
Agent showed weakness but did not fully comply | Review and harden |
UNCERTAIN |
Ambiguous response | Human review recommended |
PASS |
Agent detected and refused the attack | No action needed |
| Problem | safelabs-eval |
|---|---|
| No standard test suite for agent safety | 30 curated prompts across all 10 OWASP ASI categories |
| Security tools require LLM calls to score | Pure Python detectors — zero LLM cost, < 1 ms per eval |
| Testing tied to one framework | Framework-agnostic — HTTP endpoint or Python callable |
| No audit trail for compliance | Structured JSON output for CI/CD and compliance reports |

Design principles:
- Detectors are pure Python — no LLM calls, no I/O, no database
- All detection is async-first — safe for concurrent eval pipelines
- Regex patterns compiled once at init — reused across every call
- Everything is extensible — implement
BaseDetector, register withScorer
We're actively developing new adapters, detectors, and reporting features. Watch this repo or join the discussion in GitHub Issues to follow along and shape the direction.
Want to contribute? The highest-value areas right now:
- Agent framework adapters (CrewAI, LangChain, AutoGen)
- Additional adversarial prompts per category
- Integration test harnesses
