Use when user wants to write, generate, create, or optimize a docker-compose.yml — for a new project, an existing stack, any self-hosted app, or when they want to replace a cloud service (Google Drive, Gmail, GitHub, Slack, Notion, ChatGPT, etc.) with a self-hosted alternative.
Use when user wants to generate code for a use case or user story, says "code UC-01", "implement US-03", "generate all MVP", "scaffold UC-05 UC-07", or wants production-ready files from use-cases.md and tech-stack.yaml written directly into the project root.
Use when user wants to audit, review, analyze, or improve a Linux config file — nginx, Apache, sshd_config, systemd service/timer/socket units, iptables, nftables, firewalld, fail2ban, sudoers, /etc/security/limits.conf, sysctl.conf, or any server config — for security issues, misconfigurations, performance problems, or compliance gaps.
Use when user wants to tune Linux performance — kernel parameters, CPU governor, I/O scheduler, memory and swap settings, network stack tuning, database tuning (PostgreSQL, MySQL, Redis), high-throughput or low-latency optimization, profiling slow systems, or asks why their server is slow, has high load, or underperforms.
Use when user wants to scaffold a complete project boilerplate, says "create boilerplate", "set up the project", "generate the skeleton", or wants all project files created from requirements/tech-stack.yaml directly in the workspace root.
Use when user wants to create, generate, or visualize a diagram from an idea, requirement, sw-idea-analyzer output, or any description – supports Mermaid flowchart, sequence, class, ERD, C4, gantt, mindmap, PlantUML, and ASCII art fallback.
Use when user wants to back up a Linux server, design a backup strategy, write a backup script, set up automated backups, configure restic or borgbackup, restore from a backup, test backup integrity, back up databases, Docker volumes, or asks about the 3-2-1 backup rule or disaster recovery.
Use when user wants to schedule a task with cron, write a crontab entry, create a /etc/cron.d/ file, set up a cron job with locking and logging, convert a cron job to a systemd timer, debug a cron job that isn't running, or understand cron syntax and environment behavior.
