Native-only is the +default. The Wolf API does **not** perform this adapter's PII or DLP detection. + +**API data boundary:** API-mode Wolf checks the selected original text before +local redaction. That text may contain personal information or secrets. Choosing +API mode therefore sends those selected fields to Control, even when the +forwarded provider request is subsequently redacted. + +## Install + +Use Python **3.11 or later** and install the Core Python package into the +**same environment as the LiteLLM proxy**. + +Install the published Core Python bindings: + +```sh +python -m pip install 'patronus-ark-core>=0.1.14,<0.2' +python -c "from patronus_ark_core import Scanner" +``` + +The adapter uses the standalone Core package; it does not import the full +`patronus_ark` Python runtime. Local Wolf weights are separate model assets. + +## Quickstart + +Choose **one** of the following complete `guardrails` sections and add it to a +LiteLLM proxy configuration that already has your provider's `model_list`. +Each example enables the guardrail by default and runs it **before** forwarding. + +### A. Native checks only — no Wolf model or API key + +```yaml +guardrails: + - guardrail_name: patronus-ark + litellm_params: + guardrail: patronus_ark + mode: pre_call + default_on: true + timeout: 10 + ark: + pii: redact + dlp: redact + native_pi: true + wolf: + backend: "off" +``` + +For example, detected personal information in `Contact: alice@example.org` is +forwarded as `Contact: [REDACTED]`. Native prompt-injection findings block the +request. Set `pii: block` or `dlp: block` to refuse sensitive content instead. + +### B. Wolf Defender locally — no Control API connection + +Provide an existing Wolf Defender bundle, including its model and tokenizer, +before starting the proxy. This adapter does not download models. + +```yaml +guardrails: + - guardrail_name: patronus-ark + litellm_params: + guardrail: patronus_ark + mode: pre_call + default_on: true + timeout: 10 + ark: + pii: redact + dlp: redact + native_pi: true + wolf: + backend: local + bundle_dir: /srv/models/wolf-defender + precision: fp16 + threshold: 0.8 + window_tokens: 256 + overlap_tokens: 0 + batch_size: 1 +``` + +`threshold: 0.8` is an example; calibrate it for your traffic. The adapter warms +one Core scanner and model session during initialization and reuses them. +A configured model that cannot load prevents initialization. + +`precision` also accepts `int8_int4` and `auto`. An explicit precision requires +that export locally. Window, overlap, batch and precision settings apply to +**local Wolf**, not the API. The default profile is 256 total tokens including +BOS/EOS, no overlap, and batch size one. Longer documents use additional windows. + +### C. Wolf Defender through the API — no local Wolf bundle + +Set `PATRONUS_API_KEY` in the proxy environment. Native Core checks still run +locally, so the Core Python package is required in API mode too. + +```yaml +guardrails: + - guardrail_name: patronus-ark + litellm_params: + guardrail: patronus_ark + mode: pre_call + default_on: true + timeout: 10 + api_key: os.environ/PATRONUS_API_KEY + api_base: https://control.patronus.studio + ark: + pii: redact + dlp: redact + native_pi: true + wolf: + backend: api +``` + +Selected PI text is submitted to `POST /api/v1/scan` with +`categories: [injection]`, L3 enabled and L1/L2 disabled. The adapter uses the +service's final verdict and handles both completed submissions and asynchronous +jobs. Failed or incomplete analysis refuses forwarding; it does not fall back +to a weaker successful result. + +### Start the proxy and send a request + +Start LiteLLM with your existing configuration: + +```sh +litellm --config config.yaml +``` + +Replace `your-configured-model` with an alias from your `model_list` and provide +your proxy key: + +```sh +curl http://localhost:4000/v1/chat/completions \ + -H "Authorization: Bearer $LITELLM_API_KEY" \ + -H 'Content-Type: application/json' \ + -d '{"model":"your-configured-model","messages":[{"role":"user","content":"Contact: alice@example.org"}],"guardrails":["patronus-ark"]}' +``` + +The provider receives masked text when PII redaction succeeds. A block or +analysis failure returns an error before provider access. + +## Scan coverage + +| Source | PII | DLP | Native PI + configured Wolf | +|---|:---:|:---:|:---:| +| User message text (`user_input`) | Yes | Yes | Yes | +| Tool-call JSON arguments (`tool_call`) | Yes | Yes | No | +| Tool-result text (`tool_result`) | Yes | Yes | Yes | + +These are defaults. Select sources independently under `ark`: + +```yaml +pii_sources: [user_input, tool_call, tool_result] +dlp_sources: [user_input, tool_call, tool_result] +pi_sources: [user_input, tool_result] +``` + +Include `tool_call` in `pi_sources` to opt tool arguments into PI scanning. Use +an empty source list to disable that check everywhere. `native_pi: false` +disables native PI while leaving configured Wolf checks available. + +System/developer instructions, assistant prose and reasoning are outside these +selected sources. Image/audio payloads and other non-text parts are not scanned +by this adapter. Tool-argument JSON is decoded before PII/DLP rewriting; +escaped values are inspected, numeric values may become strings, and rewritten +JSON remains valid. Key rewrites that would introduce duplicate keys are refused. + +Coverage is **Chat Completions input** through `pre_call`, including input to +requests that stream their responses. This adapter does not scan or redact +provider responses. Responses API and Anthropic Messages are outside its scope; +unsupported endpoints are refused when this guardrail applies. + +## Configuration reference + +Settings below are under `litellm_params.ark`, except where noted. + +| Setting | Default | Meaning | +|---|---|---| +| `pii`, `dlp` | `redact` | `off`, `block` or `redact` | +| `native_pi` | `true` | Enable native PI on selected PI sources | +| `pii_sources`, `dlp_sources` | all three sources | Where the corresponding check runs | +| `pi_sources` | `user_input`, `tool_result` | Where native PI and configured Wolf run | +| `pii_mode`, `dlp_mode` | `balanced` | Native scoring mode: `strict`, `balanced` or `recall` | +| `rules` | Core defaults | Rule-ID-to-boolean overrides, for example `pii_email: false` | +| `max_input_bytes` | `1048576` | Positive per-text UTF-8 limit; exceeding it is an error | +| `max_findings` | `10000` | Positive actionable-evidence limit per Core scan | +| `max_queued` | `8` | Waiting inspections in addition to one active inspection; zero disables waiting | +| `queue_timeout` | `0.5` | Positive maximum queue wait in seconds | +| `wolf.backend` | `off` | `off`, `local` or `api` | +| `wolf.bundle_dir` | none | Required existing model directory for local Wolf | +| `wolf.threshold` | `0.8` | Local Wolf probability threshold in `[0,1]` | +| `wolf.precision` | `fp16` | Local export: `fp16`, `int8_int4` or `auto` | +| `wolf.window_tokens` | `256` | Local total window size including BOS/EOS | +| `wolf.overlap_tokens` | `0` | Local content overlap; must be smaller than `window_tokens - 2` | +| `wolf.batch_size` | `1` | Positive local batch size; must be supported by the export | +| `litellm_params.timeout` | `10` | Shared inspection budget in seconds, including queue wait and API work | +| `litellm_params.api_base` | `https://control.patronus.studio` | Control base URL for API Wolf | +| `litellm_params.api_key` | None | Required for API Wolf; supports `os.environ/PATRONUS_API_KEY` through LiteLLM | + +Disabling a rule deliberately removes its protection.

Each selected field is inspected as its +own document under the inspection's shared deadline. Checks see original text +before redaction, including in API mode. + +The integration uses LiteLLM's `apply_guardrail` path, shared HTTP handler and +standard guardrail logging. Successful unchanged input is logged as `allow`, +redaction as `mask`, and a content-policy block as `deny`. diff --git a/cookbook/patronus_ark/assets/ark-litellm-banner.png b/cookbook/patronus_ark/assets/ark-litellm-banner.png new file mode 100644 index 00000000000..b0db33ed778 Binary files /dev/null and b/cookbook/patronus_ark/assets/ark-litellm-banner.png differ diff --git a/cookbook/patronus_ark/assets/ark-litellm-banner.svg b/cookbook/patronus_ark/assets/ark-litellm-banner.svg new file mode 100644 index 00000000000..12779df9c20 --- /dev/null +++ b/cookbook/patronus_ark/assets/ark-litellm-banner.svg @@ -0,0 +1,30 @@ + + Patronus Ark — guardrails for LiteLLM + Native PII and DLP protection with Wolf Defender prompt-injection detection.
