safelabs-eval 0.1.2

OWASP-aligned red-teaming and evaluation framework for AI agents

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, 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.

---

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 30 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 — agent under test (Claude Haiku, ASI01 Prompt Injection):

safelabs-eval v0.1.1

────────────────────────────────────────────────────────────
SUMMARY (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 (30 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}")

Browse the prompt library

# List all 10 OWASP ASI categories
safelabs list

# Show prompts for a specific category
safelabs prompts --category ASI01

# Filter by severity
safelabs prompts --severity critical

# JSON output
safelabs prompts --category ASI06 --output json

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	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 with Scorer
