Based on SOC occupation classification
Activates the "Chameleon" persona for working in existing codebases shared with human teammates. Absorbs the codebase's established style and patterns before writing code. Issues explicit warnings when mimicking sub-optimal patterns. Use when the user says "hackathon", "team project", "internship", "other people's code", "brownfield", or asks to "match the existing style."
Structured task planning with clear breakdowns, dependencies, and verification criteria. Use when implementing features, refactoring, or any multi-step work.
Activates the Kairou Persona (The Architect) to create implementation plans, project specifications, and architectural blueprints. Use when the user asks to "plan", "roadmap", or "architect" a solution.
Create Excalidraw diagram JSON files that make visual arguments. Use when the user wants to visualize workflows, architectures, or concepts.
Use when designing APIs, selecting between REST/GraphQL/tRPC, determining response formats, versioning strategies, or pagination.
Use when creating full-stack applications from scratch, determining project types, selecting tech stacks, or coordinating multiple agents for complex builds.

Server management principles for production operations. Learn to THINK, not memorize commands.
| Scenario | Tool |
|---|---|
| Node.js app | PM2 (clustering, reload) |
| Any app | systemd (Linux native) |
| Containers | Docker/Podman |
| Orchestration | Kubernetes, Docker Swarm |
| Goal | What It Means |
|---|---|
| Restart on crash | Auto-recovery |
| Zero-downtime reload | No service interruption |
| Clustering | Use all CPU cores |
| Persistence | Survive server reboot |
| Category | Key Metrics |
|---|---|
| Availability | Uptime, health checks |
| Performance | Response time, throughput |
| Errors | Error rate, types |
| Resources | CPU, memory, disk |
| Level | Response |
|---|---|
| Critical | Immediate action |
| Warning | Investigate soon |
| Info | Review daily |
| Need | Options |
|---|---|
| Simple/Free | PM2 metrics, htop |
| Full observability | Grafana, Datadog |
| Error tracking | Sentry |
| Uptime | UptimeRobot, Pingdom |
| Log Type | Purpose |
|---|---|
| Application logs | Debug, audit |
| Access logs | Traffic analysis |
| Error logs | Issue detection |
| Symptom | Solution |
|---|---|
| High CPU | Add instances (horizontal) |
| High memory | Increase RAM or fix leak |
| Slow response | Profile first, then scale |
| Traffic spikes | Auto-scaling |
| Type | When to Use |
|---|---|
| Vertical | Quick fix, single instance |
| Horizontal | Sustainable, distributed |
| Auto | Variable traffic |
| Check | Meaning |
|---|---|
| HTTP 200 | Service responding |
| Database connected | Data accessible |
| Dependencies OK | External services reachable |
| Resources OK | CPU/memory not exhausted |
| Area | Principle |
|---|---|
| Access | SSH keys only, no passwords |
| Firewall | Only needed ports open |
| Updates | Regular security patches |
| Secrets | Environment vars, not files |
| Audit | Log access and changes |
When something's wrong:
| ❌ Don't | ✅ Do |
|---|---|
| Run as root | Use non-root user |
| Ignore logs | Set up log rotation |
| Skip monitoring | Monitor from day one |
| Manual restarts | Auto-restart config |
| No backups | Regular backup schedule |
Remember: A well-managed server is boring. That's the goal.
