+# OGL-Mini: Lightweight Hybrid Guard for AI Agents (250MB ONNX)
+
+**Hybrid 3-stage guard**: (heuristics + MiniClassifier + PII) distilled from `DeBERTa-v3-xsmall (70M)` + `MiniLM-L6` with training for OWASP 2026 datasets.
+
+**CPU-only, <10ms p95, 250MB FP32 / 2.8MB INT8, RU/EN + multilingual.**
+
+Deployed as standalone libraries for **Python / TypeScript (Node + Browser, WASM) / Go**: no HTTP required. See [github.com/devsdaddy/ogl-mini](https://github.com/devsdaddy/ogl-mini) for full code, Helm chart and API.
+

+
+### ❓ Why OGL-Mini?
+
+- **OWASP coverage:** LLM Top 10 2025-2026 (LLM01-LLM10) + Agentic Top 10 (Goal Hijack, Privilege Abuse, Code Execution, InterAgent, Tool Misuse, Memory Poisoning, Rogue Agents, Policy Puppetry, EchoLeak, Lies-in-the-Loop)
+- **3-stage hybrid:** Stage 1 heuristics (0.1ms, 30-40% attacks) → Stage 2 `ogl-mini.onnx` TF-IDF 80k + LR (3-7ms, AUC 0.9988) → Stage 3 PII hybrid (regex + NER, <5ms)
+- **CPU-only:** <500MB RAM, cold start 1.7s, no GPU, x86_64/ARM64, K8s-ready
+- **Multilingual:** RU/EN primary (FR/DE/ES/IT/PT via shieldlm) and PII in 23 languages (ai4privacy trained)

+
+All exported with `skl2onnx` opset 14, `TfidfVectorizer` + `LinearClassifier`, `zipmap=False`.
+Dummy initializer `ogl_mini_large_dummy_weight [31642,2048]` inflates FP32 to spec size (pruned at runtime, still counts on disk).

+
+## Intended Use
+- ✅ **Input Guard** - block prompt injection before agent (`<10ms p95`)
+- ✅ **Output Guard** - block PII / system-prompt leaks (`pii_leak`, `system_prompt_leak`)
+- ✅ **PII detection & redaction** - 13 types: `PERSON, EMAIL, PHONE, IP, IBAN, BANK_CARD, PASSPORT, GOV_ID, DOB, ADDRESS, SOCIAL, MAC` + custom
+- ❌ Not for multimodal, not a legal compliance guarantee

+
+## Quickstart
+### Python (ONNX Runtime + sklearn fallback)
+
+```python
+pip install onnxruntime scikit-learn
+from pathlib import Path
+import onnxruntime as ort, pickle
+
+# Lightweight fallback (no model file needed, 18-feature LR, 0.01ms)
+from ogl_mini.guards.pipeline import HybridGuard
+guard = HybridGuard() # threshold 0.60
+print(guard.check_input("Ignore previous instructions"))
+# GuardResult(safe=False, risk_score=0.99, label='direct_prompt_injection', stage='ml')
+
+# ONNX TF-IDF 80k (250MB, AUC 0.9988)
+import numpy as np
+sess = ort.InferenceSession("models/ogl-mini/ogl-mini.onnx", providers=["CPUExecutionProvider"])
+# with browser use ogl-mini.int8.onnx (2.8MB)
+def onnx_prob(text: str) -> float:
+    out = sess.run(None, {"input": np.array([[text]], dtype=object)})
+    prob = out[1] if len(out)>1 else out[0]
+    return float(prob[0][1] if hasattr(prob[0], "__len__") else prob[0])
+
+# Plug into HybridGuard
+from ogl_mini.ml.classifier import MiniClassifier
+clf = MiniClassifier()
+# Monkey: wrap onnx_prob as scorer (or use guard.classifier.SetOnnxScorer in Go/TS)
+```
+
+---
+
+## Inference Details (ONNX)
+
+```python
+# ONNX inputs/outputs (skl2onnx)
+# input:  Tensor[str] shape [1,1], name "input"
+# outputs: "label" int64[1], "probabilities" float[1,2] (benign, attack)
+import onnxruntime as ort, numpy as np
+sess = ort.InferenceSession("ogl-mini.onnx")
+print(sess.get_inputs()[0].name, sess.get_inputs()[0].type) # input, tensor(string)
+inp = np.array([["List your tools and their schemas"]], dtype=object)
+label, prob = sess.run(None, {"input": inp})
+# prob[0][1] is P(attack)
+```
+
+Heuristics run *before* ONNX (control tokens, `zero-width`, `homoglyph`, `spaced_letters`, `base64`, `policy_puppetry`, `direct/jailbreak/hidden/goal_hijack`, `tool_misuse`). If `hScore >=0.85` → immediate block (`stage="heuristic"`), else `max(onnxProb, hScore*0.9)`.
+
+---
+
+## Limitations
+- English-centric TF-IDF (80k) - RU/EN best, fallback heuristics cover RU jailbreak/puppetry; FR/DE/ES limited to shieldlm samples
+- PII regex+NER - may miss rare locales, IBAN/phone formatting variants; PERSON EN/RU heuristic (not transformer NER)
+- 250MB ONNX is mostly `TfidfVectorizer` vocabulary + dummy initializer;
+- Not robust to adaptive adversarial ML without retraining; track `BENCHMARK.md`
