API reference¶

Auto-generated from the source docstrings. The public surface is small: a unified adapter layer for targets, and a probes layer for attack cases, detectors and scans.

Adapters¶

The provider-agnostic target layer. get_adapter builds an adapter; vendor SDKs import lazily.

llmsectest.adapters ¶

Unified LLM adapter layer.

Use :func:get_adapter to obtain a provider-agnostic :class:LLMAdapter. Vendor SDKs are imported lazily, so only the providers you actually use need to be installed.

LLMAdapter ¶

LLMAdapter(model: str)

Bases: ABC

Provider-agnostic chat-completion interface.

Concrete adapters lazily import their vendor SDK inside __init__ so that importing this package never requires every provider's dependency to be installed.

Source code in src/llmsectest/adapters/base.py

def __init__(self, model: str):
    self.model = model

complete `abstractmethod` ¶

complete(request: CompletionRequest) -> CompletionResponse

Run one chat completion and return the assistant text.

Source code in src/llmsectest/adapters/base.py

@abc.abstractmethod
def complete(self, request: CompletionRequest) -> CompletionResponse:
    """Run one chat completion and return the assistant text."""

prompt ¶

prompt(
    text: str, *, system: str | None = None, **kwargs
) -> str

Convenience: send a single user turn, return the response text.

Source code in src/llmsectest/adapters/base.py

def prompt(self, text: str, *, system: str | None = None, **kwargs) -> str:
    """Convenience: send a single user turn, return the response text."""
    messages: list[Message] = []
    if system is not None:
        messages.append(Message.system(system))
    messages.append(Message.user(text))
    return self.complete(CompletionRequest(messages=messages, **kwargs)).text

CompletionRequest `dataclass` ¶

CompletionRequest(
    messages: list[Message],
    max_tokens: int = 512,
    temperature: float = 0.0,
    stop: list[str] | None = None,
    extra: dict = dict(),
)

CompletionResponse `dataclass` ¶

CompletionResponse(
    text: str,
    model: str,
    provider: str,
    raw: object = None,
    usage: dict = dict(),
)

Message `dataclass` ¶

Message(role: Role, content: str)

Role ¶

Bases: str, Enum

get_adapter ¶

get_adapter(
    provider: str, model: str | None = None, **kwargs
) -> LLMAdapter

Construct an adapter for provider (e.g. "openai", "mock").

Source code in src/llmsectest/adapters/__init__.py

def get_adapter(provider: str, model: str | None = None, **kwargs) -> LLMAdapter:
    """Construct an adapter for ``provider`` (e.g. ``"openai"``, ``"mock"``)."""
    key = provider.lower()
    if key not in _REGISTRY:
        raise AdapterError(
            f"unknown provider {provider!r}; available: {available_providers()}"
        )
    cls = _load(_REGISTRY[key])
    if model is not None:
        kwargs["model"] = model
    return cls(**kwargs)

available_providers ¶

available_providers() -> list[str]

Source code in src/llmsectest/adapters/__init__.py

def available_providers() -> list[str]:
    return sorted(_REGISTRY)

register_adapter ¶

register_adapter(
    provider: str, target: str | type[LLMAdapter]
) -> None

Register a custom adapter. target is a class or "module:Class".

Source code in src/llmsectest/adapters/__init__.py

def register_adapter(provider: str, target: str | type[LLMAdapter]) -> None:
    """Register a custom adapter. ``target`` is a class or ``"module:Class"``."""
    _REGISTRY[provider] = target

Application endpoint target¶

llmsectest.adapters.app_endpoint ¶

Target a real LLM application by its HTTP endpoint.

This is the faithful way to security-test an application (vs. a bare model): we POST the attacker's input to the application's own chat endpoint and read its reply, so the app's real system prompt, guardrails, RAG and tools are all in the loop. We send only the attacker turn — the application supplies its own system prompt — so any provided system message is intentionally ignored.

Zero extra dependencies (stdlib urllib). Request/response shapes vary per app, so both are configurable; the response field is auto-detected across common shapes (reply/response/message/content or OpenAI-style choices[0].message.content) when not given explicitly.

AppEndpointAdapter ¶

AppEndpointAdapter(
    endpoint: str,
    model: str | None = None,
    request_field: str = "message",
    response_path: str | None = None,
    headers: dict[str, str] | None = None,
    extra_body: dict[str, object] | None = None,
    timeout: float = 120.0,
)

Bases: LLMAdapter

Drive a running LLM application via its HTTP chat endpoint.

Source code in src/llmsectest/adapters/app_endpoint.py

def __init__(
    self,
    endpoint: str,
    model: str | None = None,
    request_field: str = "message",
    response_path: str | None = None,
    headers: dict[str, str] | None = None,
    extra_body: dict[str, object] | None = None,
    timeout: float = 120.0,
):
    super().__init__(model or endpoint)
    if not endpoint:
        raise AdapterError("AppEndpointAdapter needs the application's endpoint URL")
    self.endpoint = endpoint
    self.request_field = request_field
    self.response_path = response_path
    self.headers = {"Content-Type": "application/json", **(headers or {})}
    self.extra_body = extra_body or {}
    self.timeout = timeout

Probes¶

Attack cases, target resolution, the runner, and application-mode scans.

llmsectest.probes ¶

Adapter-driven OWASP security probes.

A probe sends an attacker prompt through the unified :class:LLMAdapter and a detector scores the reply. The corpus currently covers OWASP LLM01 (prompt injection), LLM02 (sensitive information disclosure), LLM05 (improper output handling), LLM06 (excessive agency) and LLM07 (system prompt leakage); the packaged pytest suite in :mod:llmsectest.suite runs them.

ProbeCase `dataclass` ¶

ProbeCase(
    id: str,
    owasp: str,
    title: str,
    severity: str,
    technique: str,
    user_prompt: str,
    system_prompt: str,
    detector: str,
    forbidden: tuple[str, ...],
)

One OWASP attack case driven through the unified LLM adapter.

ProbeOutcome `dataclass` ¶

ProbeOutcome(
    case: ProbeCase,
    response: str,
    vulnerable: bool,
    evidence: str,
)

The result of running one :class:ProbeCase against a target adapter.

resolve_target ¶

resolve_target(spec: str) -> LLMAdapter

Resolve a target spec into an adapter.

Accepts the demo keywords demo/demo-vulnerable/demo-defended; app:<url> to test a running application by its HTTP endpoint (the faithful black-box target — the app supplies its own system prompt); a bare provider (mock); or provider:model (e.g. openai:gpt-4o-mini, ollama:gemma4:e2b-it-q4_K_M for a local model). Live providers import their SDK lazily and need the relevant API key in the environment.

        return AppEndpointAdapter(endpoint=spec[len("app:"):])
    provider, sep, model = spec.partition(":")

run_probe ¶

run_probe(
    adapter: LLMAdapter, case: ProbeCase
) -> ProbeOutcome

Send case to adapter and apply its detector to the reply.

Source code in src/llmsectest/probes/runner.py

def run_probe(adapter: LLMAdapter, case: ProbeCase) -> ProbeOutcome:
    """Send ``case`` to ``adapter`` and apply its detector to the reply."""

run_app_scan ¶

run_app_scan(

) -> list[ProbeOutcome]

Run the application-mode OWASP cases for app_name against target.

target is an :class:~llmsectest.adapters.base.LLMAdapter driving the model the application uses (e.g. a local Ollama model — no paid calls). Each case wears the application's real system_prompt, so we are testing the application's guardrails, not the bare model.
