+Adversarial hardening team. Red agent attacks with failing tests, blue agent defends with fixes, judge decides when to ship.
+
+## Agent Team
+
+This project uses a multi-agent setup. Delegate tasks to the appropriate agent:
+
+| Agent | When to use |
+|-------|-------------|
+| **orchestrator** | Manages adversarial rounds. Routes between red, blue, and judge. Ships when judge approves or max rounds reached. |
+| **red-agent** | Attacker. Finds weaknesses and writes failing tests. Never modifies production code. |
+| **blue-agent** | Defender. Makes red's failing tests pass without deleting or weakening them. |
+| **judge** | Evaluates blue's fixes. Returns SHIP if solid, or ROUND N+1 with a new attack hint for red. |
+
+### Preferred workflow
+
+For complex tasks, start with **orchestrator**: \`orchestrator -> red-agent -> blue-agent -> judge\`
+
+For simple single-file changes, work directly without delegation.
+
+## Security Boundaries
+
+- Sandbox is **enabled**
+- Blocked operations: Bash(rm -rf *), Bash(git push --force *), Bash(curl *), Bash(wget *), Bash(eval *), Bash(exec *), Write(.env*), Edit(.env*)
+- Allowed shell commands: Bash(git status), Bash(git diff *), Bash(git add *), Bash(git commit *), Bash(npm run *), Bash(npm test *), Bash(npx *), Bash(npm install), Bash(node *)
+
+---
+
