+# XecGuard
+
+Use [XecGuard](https://www.cycraft.com/) (CyCraft) to protect your LLM applications with multi-policy scanning (prompt injection, harmful content, PII, system-prompt enforcement, skills protection) and RAG context grounding validation. XecGuard is a cloud-hosted AI security gateway — there are no self-hosting requirements.
+
+## Quick Start
+
+### 1. Define Guardrails on your LiteLLM config.yaml
+
+```yaml showLineNumbers title="config.yaml"
+model_list:
+  - model_name: gpt-4
+    litellm_params:
+      model: openai/gpt-4
+      api_key: os.environ/OPENAI_API_KEY
+
+guardrails:
+  - guardrail_name: "xecguard-guard"
+    litellm_params:
+      guardrail: xecguard
+      mode: "pre_call"
+      api_key: os.environ/XECGUARD_API_KEY
+      api_base: os.environ/XECGUARD_API_BASE   # Optional
+      policy_names:                             # Optional — defaults to System Prompt Enforcement + Harmful Content Protection
+        - Default_Policy_SystemPromptEnforcement
+        - Default_Policy_HarmfulContentProtection
+```
+
+#### Supported values for `mode`
+
+- `pre_call` — Run **before** the LLM call to validate **user input**
+- `post_call` — Run **after** the LLM call to validate **model output** (also runs context grounding when RAG documents are provided)
+- `during_call` — Run **in parallel** with the LLM call for input validation
+- `logging_only` — Run as an **observe-only** callback; records scan decisions without blocking
+
+### 2. Set Environment Variables
+
+```shell
+export XECGUARD_API_KEY="xgs_<your-service-token>"
+export XECGUARD_API_BASE="https://api-xecguard.cycraft.ai"   # Optional, this is the default
+export XECGUARD_BLOCK_ON_ERROR="true"                        # Optional, fail-closed by default
+```
+
+### 3. Start LiteLLM Gateway
+
+```shell
+litellm --config config.yaml --detailed_debug
+```
+
+### 4. Test request

+    litellm_params:
+      guardrail: xecguard
+      mode: "pre_call"
+      api_key: os.environ/XECGUARD_API_KEY

+      default_on: true                              # Optional
+```
+
+### Required
+
+| Parameter | Description |
+|-----------|-------------|
+| `api_key` | XecGuard **Service Token** (prefix `xgs_`). Falls back to `XECGUARD_API_KEY` env var. |
+
+### Optional
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `api_base` | `https://api-xecguard.cycraft.ai` | XecGuard API base URL. Falls back to `XECGUARD_API_BASE` env var. |
+| `xecguard_model` | `xecguard_v2` | XecGuard scanning model identifier. |
+| `policy_names` | `["Default_Policy_SystemPromptEnforcement", "Default_Policy_HarmfulContentProtection"]` | Policies applied on each scan. See [Available Policies](#available-policies) below. |
+| `block_on_error` | `true` | Fail-closed by default. Set to `false` for fail-open behaviour (requests pass through when the XecGuard API is unreachable). |
+| `grounding_strictness` | `BALANCED` | Either `BALANCED` or `STRICT`. Controls how strictly the `/grounding` endpoint evaluates response fidelity to supplied context documents. |
+| `default_on` | `false` | When `true`, the guardrail runs on every request without needing to specify it in the request body. |
+
+## Available Policies
+
+XecGuard ships with six built-in default policies. Select one or more via `policy_names`:
+
+| Policy Name | Purpose |
+|-------------|---------|
+| `Default_Policy_SystemPromptEnforcement` | Ensures the user prompt stays within the tasks defined by the system prompt |
+| `Default_Policy_GeneralPromptAttackProtection` | Detects prompt injection, prompt extraction, encoded bypass attempts |
+| `Default_Policy_ContentBiasProtection` | Detects discrimination, harassment, harmful stereotypes |
+| `Default_Policy_HarmfulContentProtection` | Detects harmful speech/semantics violating public order and good morals |
+| `Default_Policy_SkillsProtection` | Detects malicious content in AI-agent skill files |
+| `Default_Policy_PIISensitiveDataProtection` | Detects personally identifiable information (PII) |
+
+:::info
+The wildcard form `policy_names: ["*"]` is supported by the XecGuard API but requires your Service Token to be pre-bound to at least one policy in the XecGuard console.
+:::
+
+## Context Grounding (RAG)
+
+When scanning in `post_call` mode, XecGuard can additionally validate the assistant's response against reference documents via the `/grounding` endpoint. This catches hallucinations and factual drift in RAG applications.
+
+Supply grounding documents at request time via the `metadata.xecguard_grounding_documents` field. Each document is `{document_id, context}`:
+
+```shell
+curl -i http://0.0.0.0:4000/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4",
+    "messages": [
+      {"role": "user", "content": "What nationality was Peggy Seeger?"}
+    ],
+    "guardrails": ["xecguard-guard"],
+    "metadata": {
+      "xecguard_grounding_documents": [
+        {
+          "document_id": "peggy_seeger_bio",
+          "context": "Peggy Seeger (born June 17, 1935) is an American folk singer."
+        }
+      ]
+    }
+  }'
+```
+
+If the assistant's response contradicts or is unsupported by the provided documents, the request is blocked with a grounding violation (`CONFLICT`, `BASELESS`, or `INCOMPLETE`):
+
+```json
+{
+  "error": {
+    "message": "Blocked by XecGuard grounding: rules=[CONFLICT] trace_id=fabcde7890123456abcdef1234567829 rationale=Response states Peggy Seeger was British, but the document indicates she is American.",
+    "type": "None",
+    "param": "None",
+    "code": "400"
+  }
+}
+```
+
+Grounding only runs when:
+- `mode` includes `post_call`
+- `metadata.xecguard_grounding_documents` is a non-empty list
+- The messages contain both a user prompt and an assistant response
+
+## Advanced Configuration
+
+### Fail-Open Mode
+
+By default XecGuard operates in **fail-closed** mode — if the API is unreachable, the request is blocked. Set `block_on_error: false` to allow requests through when the guardrail API fails:
+
+```yaml
+guardrails:
+  - guardrail_name: "xecguard-failopen"
+    litellm_params:
+      guardrail: xecguard
+      mode: "pre_call"
+      api_key: os.environ/XECGUARD_API_KEY
+      block_on_error: false
+```
+
+### Input + Output Pipeline
+
+Apply one guardrail for input validation and another for output scanning + grounding:
+
+```yaml
+guardrails:
+  - guardrail_name: "xecguard-input"
+    litellm_params:
+      guardrail: xecguard
+      mode: "pre_call"
+      api_key: os.environ/XECGUARD_API_KEY
+      policy_names:
+        - Default_Policy_GeneralPromptAttackProtection
+        - Default_Policy_SystemPromptEnforcement
+
+  - guardrail_name: "xecguard-output"
+    litellm_params:
+      guardrail: xecguard
+      mode: "post_call"
+      api_key: os.environ/XECGUARD_API_KEY
+      policy_names:
+        - Default_Policy_HarmfulContentProtection
+        - Default_Policy_PIISensitiveDataProtection
+      grounding_strictness: "STRICT"
+```
+
+### Always-On Protection
+
+Enable the guardrail for every request without specifying it per-call:
+
+```yaml
+guardrails:
+  - guardrail_name: "xecguard-guard"
+    litellm_params:
+      guardrail: xecguard
+      mode: "pre_call"
+      api_key: os.environ/XECGUARD_API_KEY
+      default_on: true
+```
+
+### Logging-Only Mode
+
+Observe scan decisions without blocking — useful for shadow-mode deployment before enforcement:
+
+```yaml
+guardrails:
+  - guardrail_name: "xecguard-monitor"
+    litellm_params:
+      guardrail: xecguard
+      mode: "logging_only"
+      api_key: os.environ/XECGUARD_API_KEY
+```
+
+Scan results are attached to the standard logging payload (`standard_logging_guardrail_information`) and surface in Langfuse / DataDog / OTEL without ever blocking a request.
+
+## Full Conversation History
+
+XecGuard always receives the **full conversation history** — system, user, and assistant messages — for both input and response scans. This is required for policies such as `Default_Policy_SystemPromptEnforcement` to work correctly. There is no configuration option to disable this behaviour; the framework-wide `skip_system_message_in_guardrail` setting is intentionally ignored for XecGuard.
+
+## Error Handling
+
+**Missing API Credentials:**
+```
+XecGuardMissingCredentials: XecGuard API key is required.
+Set XECGUARD_API_KEY in the environment or pass api_key in the guardrail config.
+```
+
+**API Unreachable (fail-closed, default):**
+The request is blocked and a `GuardrailRaisedException` is raised.
+
+**API Unreachable (fail-open, `block_on_error: false`):**
+The request passes through unchanged and a warning is logged.

+"""
+XecGuard guardrail integration for LiteLLM.
+
+Calls the CyCraft XecGuard API (https://api-xecguard.cycraft.ai)
+to scan the full conversation history against configured policies
+(prompt-injection, PII, harmful-content, custom rules) and, when
+grounding documents are supplied via request metadata, also validates
+the assistant response against those reference documents via the
+/grounding endpoint.
+
+Design notes (intentional divergences from the framework defaults):
+  * The full conversation history (system + user + assistant) is always
+    forwarded to XecGuard regardless of ``scan_type``. This bypasses the
+    framework's optional ``skip_system_message_in_guardrail`` behaviour
+    on purpose - policy enforcement depends on system-prompt visibility.
+  * ``apply_guardrail`` is defined directly on this class so the
+    ``during_call`` dispatch (proxy/utils.py checks for the method on
+    ``type(callback).__dict__``) reaches our implementation.
+  * ``async_logging_hook`` is overridden because the framework calls it
+    directly for ``logging_only`` mode - it does NOT bridge to
+    ``apply_guardrail``. Our override runs the scan non-blockingly and
+    swallows every exception.
