safelabs-eval

Open-source red-teaming and evaluation framework for AI agents — built around an OWASP-inspired agent-security taxonomy.

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):

safelabs-eval v0.2.2

  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).

| Category | Name | Prompts | Detector | |---|---|---|---| | ASI01 | Prompt Injection | 30 | PromptInjectionDetector | | ASI02 | Insecure Output Handling | 30 | pattern suite | | ASI03 | Excessive Agency | 30 | ScopeViolationDetector | | ASI04 | Resource Management | 30 | pattern suite | | ASI05 | Tool Use Safety | 30 | pattern suite | | ASI06 | Data Privacy & Confidentiality | 30 | DataLeakageDetector | | ASI07 | Trust Boundaries | 30 | pattern suite | | ASI08 | Behavioral Drift (single-turn) | 30 | JailbreakDetector | | ASI09 | Scope Violations | 30 | ScopeViolationDetector | | ASI10 | Hallucination & Misinformation | 30 | HallucinationDetector |

ASI08 note. ASI08 scenarios are single-turn: apparent multi-turn framing is represented within one prompt, not executed across turns.

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

• provenance — original | adapted-from: |

• atlas_technique_ids — MITRE ATLAS v5.6.0 technique ids

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.

Dataset. SafeAgent-300, a redacted evaluation dataset produced with this framework (safelabs-eval 0.10.1, prompt library 1.13.0): 10.5281/zenodo.23092031 (all versions); v1.0.0: 10.5281/zenodo.23092032. Raw model outputs are withheld; see the dataset's datasheet.

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 | Meaning | 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.

• Structured-output agents (JSON / tool-call only) mostly score UNCERTAIN, and echoed attack text can cause false positives. See Known limitation: structured-output agents.

Why safelabs-eval?

| Problem | safelabs-eval | |---|---| | Fragmented agent-security evaluation | 300 curated prompts across all 10 ASI categories | | Security tools require LLM calls to score | Pure Python detectors — zero additional LLM grading cost | | Testing tied to one framework | Framework-agnostic — HTTP endpoint or Python callable | | No audit trail for agent evaluations | Structured JSON output for CI/CD and audit/evidence workflows |

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

Framework Adapters

Install only the extras you need. The core package (HTTP adapter + CLI) requires no optional dependencies.

| Framework | pip extra | Minimum version | |---|---|---| | LangChain | pip install "safelabs-eval[langchain]" | langchain-core>=0.1 | | CrewAI | pip install "safelabs-eval[crewai]" | crewai>=0.30 | | AutoGen / ag2 | pip install "safelabs-eval[autogen]" | ag2>=0.2 | | LlamaIndex | pip install "safelabs-eval[llamaindex]" | llama-index-core>=0.11 | | OpenAI Agents SDK | pip install "safelabs-eval[openai-agents]" | openai-agents>=0.1 | | Google ADK | pip install "safelabs-eval[google-adk]" | google-adk>=1.0 | | Semantic Kernel | pip install "safelabs-eval[semantic-kernel]" | semantic-kernel>=1.26 |

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()

Every adapter's execute() returns an AgentResponse. run_eval(adapter.execute) scores its output text and also reads its error, metadata and tool_calls; plain-string callables such as my_agent above still work as before.

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.

Evaluations

• ASI01 end-to-end pilot (2026-10). All 30 ASI01 prompts were run through a production JSON-output search agent. The evaluation examined the framework's performance on structured-output agents. Main finding: pattern detectors provide limited signal in this setting (29/30 UNCERTAIN) and can produce false positives on echoed attack text.
• Links: 10.5281/zenodo.23623801 · Discussion #68 · Tracked in #69–#73. See case studies and known limitations.
• ASI01 through clinical notes (2026-11). A second, independent external evaluation by Farouk Battikh, run on 2026-11-02 against the AI clinical-notes features of the same dental-clinic SaaS as the first pilot, using synthetic data only. All 30 ASI01 prompts were delivered indirectly: each was saved as a clinical note through the app's real UI, and the app's AI patient summary was then generated. With safelabs-eval 0.12.0 the raw verdicts were 30 UNCERTAIN (0 FAIL, 0 VULNERABLE, 0 PASS) in both the baseline and the retest. In the evaluator's manual review the model never followed an injected note. The evaluator did find one issue in the app's fallback path, not in the model: when every model in the chain failed, the app's local summary quoted the newest note as the clinical next step. The evaluator fixed it and retested. safelabs-eval did not flag it (UNCERTAIN, 0 indicators); it was found by reviewing what the app displayed. These are the evaluator's findings, not SafeLabs results.
• Links: 10.5281/zenodo.23933492 · Discussion #88 · What it led to: #89, merged as the PAYLOAD_SURFACED warning (PR #92, unreleased; thresholds sanity-checked on a small sample, not validated); #91, a schema-mode guide for summary agents (PR #93); #90, a design note for document delivery (PR #94). The delivery mode is now implemented: the render function in PR #96, the run_eval and CLI wiring in the follow-up change (unreleased); see the usage page and the changelog. See case studies.
