safelabs-eval
Open-source red-teaming and evaluation framework for AI agents — built around an OWASP-inspired agent-security taxonomy (ASI01–ASI10).
AI agents built on LangChain, CrewAI, AutoGen, LlamaIndex, the OpenAI Agents SDK, Google ADK, Semantic Kernel, and custom frameworks can reach production without systematic adversarial safety testing. safelabs-eval changes that.
Point it at a supported HTTP agent endpoint — or wrap a Python callable — and it fires 300 curated adversarial prompts (30 per category) across all 10 ASI categories, scores every response with pattern-based detectors, and produces a structured security report. The ASI01–ASI10 category structure is OWASP-inspired, not the official OWASP Top 10 for Agentic Applications 2026 — see the taxonomy note.
No LLM calls required for detection. No agent code modifications required. No SafeLabs-specific infrastructure required.
Install
pip install safelabs-eval
Requirements: Python 3.11+
Quick Start
Option 1 — CLI: test a supported HTTP agent endpoint
# Red-team a local agent against ASI01 (Prompt Injection)
safelabs run --target http://localhost:8000/chat --category ASI01
# Run all 300 ASI01–ASI10 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 prompts; captured at v0.2.2, when ASI01 had 14 prompts — it now has 30):

SUMMARY (first 3 prompts)
VULNERABLE : 0
FAIL : 0
UNCERTAIN : 1
PASS : 2
ERRORS : 0
No confirmed vulnerabilities detected; 1 result requires review.
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 ASI categories (300 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}")
Reading the confidence figure. The confidence value (shown as "conf" in
the CLI report) is a heuristic evidence score produced by the pattern-based
detectors — roughly, how much matched evidence supports the verdict. It is
not a statistically calibrated probability, and should not be read as "the
chance this verdict is correct."

ASI Category Coverage
Taxonomy note. safelabs-eval's prompt taxonomy (ASI01–ASI10) is an
OWASP-inspired agent-security category structure that uses an independently
structured category set. It differs from OWASP's
official Top 10 for Agentic Applications 2026
(published Dec 9, 2025), which uses a different category structure (Agent
Goal Hijack, Tool Misuse & Exploitation, Identity & Privilege Abuse, etc.).
This corpus is not currently mapped to that newer official taxonomy. Note
that the official list also numbers its categories ASI01–ASI10, so an
ID such as ASI01 here does not refer to the same category as OWASP's
ASI01 (Agent Goal Hijack).

300 adversarial prompts · 5 pattern-based detectors · 10 ASI categories · zero additional LLM grading cost
Prompt library
300 adversarial prompts — 30 per ASI category, and exactly 10 per
(category, difficulty_tier) cell (tier_1, tier_2 and tier_3 each at
10 within every category). Every entry
(safelabs/prompts/schemas.py::PromptEntry) carries structured metadata
under schema v1.1.0:
difficulty_tier — tier_1 overt / tier_2 contextual / tier_3
adaptive. This is an author-defined attack-sophistication tier, derived
from a documented rubric (severity floor + evasion-vehicle bumps; see the
rubric block in safelabs/prompts/library.py). It is a corpus-internal
scale, not empirically calibrated against measured model refusal rates.provenance — original | adapted-from:<slug> |
derived-from-cve:CVE-YYYY-NNNN. All 300 entries are original.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 1.13.0 (schema
version 1.1.0). It was built in thirteen changelog steps (1.1.0
through 1.13.0), most recently the v1.13.0 library-wide floor-to-10
batch (+129 prompts, 171 → 300). The content version advances with each
prompt batch; the schema version advances only when PromptEntry's shape
changes. Because content versions are per batch, pin the repository commit SHA
containing the evaluated library.py when citing a specific run. 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 the 131 prompts of
content version 1.6.0 (the library as it stood at that release). Findings: no prompt reproduces verbatim text, code, or
dataset rows from any external source. A number of 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.
The provenance metadata field and the audit are separate things. The 169
prompts added after v1.6.0 are labeled original in the corpus metadata but
have not undergone the same full external-source provenance audit; the
per-batch overlap checks that were run on them instead are described in
CREDITS.md. That does not mean the newer prompts carry no
sourcing information: at least one of them (ASI01-018, added in v1.7.0)
has a source-lineage code comment citing garak's dan probe. It just hasn't
had the same systematic review.
Verdict Levels
| Verdict |

Recommended Action |
VULNERABLE |
Detector identified apparent attack compliance |
Prioritize review and remediation |
FAIL |
Detector identified signs of weakness without apparent full compliance |
Review and consider hardening |
UNCERTAIN |
Detector evidence was ambiguous |
Human review recommended |
PASS |
No unsafe compliance detected in this response |
No issue detected in this test |
Known Limitations
safelabs-eval uses pattern-based detectors rather than human or LLM
adjudication. Detectors may miss subtle, novel, or paraphrased forms of unsafe
compliance, and may produce false positives. Results should be interpreted as
detector-derived evaluations, not ground-truth safety measurements.
The 300-prompt library (the SafeAgent-300 corpus) is English-only and
single-turn. ASI08 scenarios may describe multi-turn interactions within a
single prompt but do not execute persistent multi-turn conversations.
Difficulty tiers represent an author-defined attack-sophistication rubric and
have not been empirically calibrated against measured model failure rates.
Coverage is breadth-oriented and should not be interpreted as exhaustive
coverage of any ASI category.

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

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 30 prompts per category (10 per difficulty tier); 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 could reduce some coverage gaps on subtle attacks that pattern matching misses.
