+InsAIts Security Monitor -- PreToolUse Hook for Claude Code
+============================================================
+
+Real-time security monitoring for Claude Code tool inputs.
+Detects credential exposure, prompt injection, behavioral anomalies,
+hallucination chains, and 20+ other anomaly types -- runs 100% locally.
+
+Writes audit events to .insaits_audit_session.jsonl for forensic tracing.
+
+Setup:
+  pip install insa-its
+  export ECC_ENABLE_INSAITS=1
+
+  Add to .claude/settings.json:
+  {
+    "hooks": {
+      "PreToolUse": [
+        {
+          "matcher": "Bash|Write|Edit|MultiEdit",
+          "hooks": [
+            {
+              "type": "command",
+              "command": "node scripts/hooks/insaits-security-wrapper.js"
+            }
+          ]
+        }
+      ]
+    }
+  }
+
+How it works:
+  Claude Code passes tool input as JSON on stdin.
+  This script runs InsAIts anomaly detection on the content.
+  Exit code 0 = clean (pass through).
+  Exit code 2 = critical issue found (blocks tool execution).
+  Stderr output = non-blocking warning shown to Claude.
+
+Environment variables:
+  INSAITS_DEV_MODE   Set to "true" to enable dev mode (no API key needed).
+                     Defaults to "false" (strict mode).
+  INSAITS_MODEL      LLM model identifier for fingerprinting. Default: claude-opus.
+  INSAITS_FAIL_MODE  "open" (default) = continue on SDK errors.
+                     "closed" = block tool execution on SDK errors.
+  INSAITS_VERBOSE    Set to any value to enable debug logging.
+
+Detections include:
+  - Credential exposure (API keys, tokens, passwords)
+  - Prompt injection patterns
+  - Hallucination indicators (phantom citations, fact contradictions)
+  - Behavioral anomalies (context loss, semantic drift)
+  - Tool description divergence
+  - Shorthand emergence / jargon drift
+
+All processing is local -- no data leaves your machine.
