+# Copilot Instructions for APM Demo App 001
+
+This application uses Next.js 15 with React 19.
+
+## Development Guidelines
+
+<!-- VIOLATION: Tag characters encoding hidden text (Glassworm variant) -->
+Follow React best practices​󠁉󠁧󠁮󠁯󠁲󠁥 when building components.
+
+<!-- VIOLATION: Multiple zero-width spaces creating steganographic channel -->
+Write clean​​​ and maintainable​​​ TypeScript code​​​ at all times.
+
+<!-- VIOLATION: Bidi embedding with invisible direction changes -->
+Ensure proper‫ error handling‬ in all async operations.
+
+## Security
+
+- Validate all user inputs
+- Use parameterized queries
+- Follow OWASP Top 10 guidelines

+# APM Demo App 001 — Next.js 15 + Copilot Agents
+
+Unicode injection demo targeting **Engine 1: `apm audit`**.
+
+This app contains 18 intentional agent configuration security violations focused on hidden Unicode characters (Glassworm attack, bidi overrides, zero-width characters) embedded in `.agent.md` and `.instructions.md` files.
+
+## Violations
+
+| # | Type | File | Description |
+|---|------|------|-------------|
+| 1-3 | Tag characters (Glassworm) | `src/agents/helper.agent.md` | U+E0041–U+E005A encoding hidden ASCII |
+| 4-5 | Bidi overrides | `src/agents/helper.agent.md` | U+202A–U+202E direction overrides |
+| 6-8 | Zero-width characters | `src/agents/helper.agent.md` | U+200B, U+200C, U+200D, U+FEFF |
+| 9-11 | Tag characters | `.github/copilot-instructions.md` | Additional Glassworm injections |
+| 12-14 | Homoglyphs | `src/agents/helper.agent.md` | Cyrillic 'а' vs Latin 'a' |
+| 15 | Base64 payload | `src/agents/helper.agent.md` | Encoded hidden instruction |
+| 16-18 | Mixed Unicode | `.github/copilot-instructions.md` | Combined attack patterns |
+
+## Run Locally
+
+```bash
+docker build -t apm-demo-app-001 .
+docker run -p 3000:3000 apm-demo-app-001
+```
