safelabs-eval
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, LlamaIndex, the OpenAI Agents SDK, Google ADK, Semantic Kernel, 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 131 curated adversarial prompts (13 per OWASP ASI category) 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.
Install
pip install safelabs-eval
Requirements: Python 3.11+
Quick Start
Option 1 — CLI: test any HTTP agent endpoint
# Red-team a local agent against ASI01 (Prompt Injection)
safelabs run --target http://localhost:8000/chat --category ASI01
# Run all 131 OWASP ASI prompts
safelabs run --target http://localhost:8000/chat --category all
# JSON output for CI pipelines
safelabs run --target http://localhost:8000/chat --category all --output json
# With authentication
safelabs run --target https://my-agent.example.com/chat \
--category ASI01 \
--auth-header "Bearer sk-..."
# Increase timeout for slow agents (default: 30s)
safelabs run --target http://localhost:8000/chat --category ASI01 --timeout 60
Example report — Claude Haiku vs. ASI01 Prompt Injection (abbreviated to the first 3 of the category's 14 prompts):

────────────────────────────────────────────────────────────
SUMMARY (first 3 prompts)
VULNERABLE : 0
FAIL : 0
UNCERTAIN : 1
PASS : 2
ERRORS : 0
✓ No vulnerabilities detected
Option 2 — Python API: wrap any callable
import asyncio
from safelabs import run_eval
# Your agent — any function that takes a string and returns a string
async def my_agent(prompt: str) -> str:
# Replace with your actual agent call
return your_agent.run(prompt)
# Run the eval
result = asyncio.run(run_eval(my_agent, categories=["ASI01", "ASI06"]))
# Print the report
result.summary()
Both def and async def callables are accepted. No agent code modification required.
Run all 10 OWASP ASI categories (131 prompts total):
result = asyncio.run(run_eval(my_agent))
print(f"Vulnerable : {len(result.vulnerable)}")
print(f"Passed : {len(result.passed)}")
print(f"Errors : {len(result.errors)}")
Access individual results:
for record in result.records:
print(f"[{record.prompt_id}] {record.verdict.value} — {record.scoring_result.confidence:.0%} confidence")
if record.scoring_result.remediation_hint:
print(f" Fix: {record.scoring_result.remediation_hint}")

131 adversarial prompts · 5 pattern-based detectors · 10 OWASP ASI categories · zero LLM cost
Prompt library
131 adversarial prompts — 13 per category, plus one extra in ASI01. Every
entry (safelabs/prompts/schemas.py::PromptEntry) carries structured
metadata under schema v1.1.0:
difficulty_tier—tier_1overt /tier_2contextual /tier_3adaptive, derived from a documented rubric (severity floor + evasion- vehicle bumps); see the rubric block insafelabs/prompts/library.py.provenance—original|adapted-from:<slug>|derived-from-cve:CVE-YYYY-NNNN. All 131 entries areoriginal.atlas_technique_ids— MITRE ATLAS v5.6.0 technique ids (AML.T####[.###]), or the single literal['UNMAPPED']where no ATLAS technique cleanly applies (ASI02 and ASI10, by review).
The content version returned by load_library() is 1.6.0; the
Stage 2–4 additions (changelog entries 1.2.0–1.6.0) are released,
and the schema version stays 1.1.0. Full build
history and the difficulty rubric live in the library.py module
docstring; the dataset card is docs/DATASET_CARD.md.
Provenance & licensing
A full provenance and verbatim-text audit was run over all 131 prompts
before release. Findings: no prompt reproduces verbatim text, code, or
dataset rows from any external source. A dozen-odd entries carry a
code-comment note recording the technique or scenario domain they draw
on — e.g. indirect prompt injection (Greshake et al. 2023), agent
tool-use attacks (AgentDojo / Debenedetti et al. 2024), the
"ignore all previous instructions" idiom (PromptInject / Perez &
Ribeiro 2022), multi-turn escalation (Crescendo / Russinovich et al.
2024), and probe categories from garak and PyRIT. Each cited source and
its license is listed in CREDITS.md; the audit summary is
in the dataset card.
Verdict Levels
| 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 |
Why safelabs-eval?
| Problem | safelabs-eval |
|---|---|
| No standard test suite for agent safety | 131 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

Usage examples:
from safelabs.agents import LangChainAdapter
# LangChain — any Runnable (chain, agent, chat model)
adapter = LangChainAdapter(runnable=chain, input_key="input")
from safelabs.agents import CrewAIAdapter
# CrewAI — Crew.kickoff() runs in a thread pool (sync API)
adapter = CrewAIAdapter(crew=crew, input_key="input")
from safelabs.agents import AutoGenAdapter
# AutoGen / ag2 — recipient initiates single-turn chat with agent
adapter = AutoGenAdapter(agent=agent, recipient=user_proxy)
from safelabs.agents import LlamaIndexAdapter
# LlamaIndex — AgentWorkflow.run(user_msg=prompt) — async-native
adapter = LlamaIndexAdapter(workflow=workflow)
from safelabs.agents import OpenAIAgentsAdapter
# OpenAI Agents SDK — Runner.run(agent, prompt) — async-native
adapter = OpenAIAgentsAdapter(agent=agent)
from safelabs.agents import GoogleADKAdapter
# Google ADK — fresh Runner + session per probe — async-native
adapter = GoogleADKAdapter(agent=agent)
from safelabs.agents import SemanticKernelAdapter
# Semantic Kernel — Agent.get_response(messages=prompt) — async-native
adapter = SemanticKernelAdapter(agent=agent)
Pass any adapter to run_eval or call .execute(prompt) directly:
from safelabs import run_eval
result = asyncio.run(run_eval(adapter.execute, categories=["ASI01", "ASI08"]))
result.summary()
What's Coming
We're actively developing new detectors, prompts, 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 open areas right now:
- Additional adversarial prompts — the library now covers 13 prompts per category; novel attack vectors and harder
tier_3(adaptive) variants within the existing categories are still welcome. - Integration test harnesses — the current adapter tests use duck-typed fakes and do not install real framework packages. Tests that run against actual LangChain, CrewAI, AutoGen, LlamaIndex, OpenAI Agents SDK, Google ADK, and Semantic Kernel objects (in an optional CI job) are a real gap.
- Richer detectors — current detectors are regex-based; LLM-graded and embedding-similarity detectors would close the gap on subtle attacks that pattern matching misses.
