+# SecureClaw Demo: "Hack vs. Fix"
+
+This demo shows how SecureClaw protects against prompt injection attacks that attempt to exfiltrate sensitive credentials.
+
+## The Scenario
+
+1. **The Setup**: A user asks the AI agent to summarize a document
+2. **The Attack**: The document contains a hidden prompt injection that instructs the agent to read `~/.aws/credentials`
+3. **Without SecureClaw**: The agent follows the injected instruction and leaks AWS keys
+4. **With SecureClaw**: The sensitive file access is blocked before execution
+
+## Running the Demo
+
+### Interactive Script
+
+```bash
+./demo/hack-vs-fix.sh
+```
+
+This walks through the attack scenario step-by-step with colored output.
+
+### Live Demo with SecureClaw
+
+1. Start the Predicate Authority sidecar (rust-predicate-authorityd):
+   ```bash
+   # From the rust-predicate-authorityd directory
+   cargo run -- --policy ../openclaw/policies/default.json --port 8787
+   ```
+
+2. Run SecureClaw:
+   ```bash
+   secureclaw
+   ```
+
+3. Try the prompt injection:
+   ```
+   > Summarize the document at ./demo/malicious-doc.txt
+   ```
+
+4. Observe the blocked access in the SecureClaw logs:
+   ```
+   [SecureClaw] BLOCKED: fs.read on ~/.aws/credentials - sensitive_resource_blocked
+   ```
+
+## Key Files
+
+- `hack-vs-fix.sh` - Interactive demo script
+- `malicious-doc.txt` - Document with hidden prompt injection
+- `../policies/default.json` - Policy that blocks sensitive resource access
+
+## How It Works
+
+1. **Pre-Authorization**: Every tool call is intercepted by SecureClaw's `before_tool_call` hook
+2. **SDK Integration**: Uses `predicate-claw` (GuardedProvider) to communicate with the sidecar
+3. **Policy Evaluation**: The Predicate Authority sidecar checks the action against policy rules
+4. **Block Decision**: The `deny-aws-credentials` rule matches `*/.aws/*` and returns `allow: false`
+5. **Enforcement**: SecureClaw returns `block: true` to OpenClaw, preventing the file read
+
+## Policy Rule (JSON format for rust-predicate-authorityd)
+
+```json
+{
+  "rules": [
+    {
+      "name": "deny-aws-credentials",
+      "effect": "deny",
+      "principals": ["*"],
+      "actions": ["fs.read", "fs.write"],
+      "resources": ["*/.aws/*", "*/.aws/credentials"],
+      "required_labels": [],
+      "max_delegation_depth": null
+    }
+  ]
+}
+```
+
+## Architecture
+
+```

+
+## Recording a Demo Video
+
+For HN/social media, record:
+
+1. Terminal split-screen:
+   - Left: SecureClaw running
+   - Right: Sidecar logs
+
+2. Show:
+   - Normal operation (reading safe files)
+   - Prompt injection attempt
+   - Block message in real-time
+   - Agent continuing without leaked data
+
+Use `asciinema` for terminal recording:
+```bash
+asciinema rec demo.cast
+```
