Applies kernel tuning, web server optimization, security hardening, and resource limits to boost Hostinger VPS performance and reduce costs.

This skill contains a small shell script that will modify kernel parameters, install packages (nginx, ufw, fail2ban) via apt, and enable the firewall. It does not request secrets, but it requires root and network access to apt repos. Actionable advice: - Do NOT run this on production systems without testing first—try on a throwaway/staging VPS. - Verify your OS is Debian/Ubuntu (script uses apt and ufw) before running; it will fail or break other distros. - Back up configs and have console access ready in case enabling UFW locks you out. The script does run 'ufw allow ssh' first, but mistakes or differences in SSH config can still cause lockout. - Note missing pieces: the SKILL.md mentions a configs/hostinger.sysctl file, cost analysis, and auto-scaling features that are not present in the package—treat those claims as unimplemented. - If you plan to use the agent to run this script autonomously, restrict that capability and require explicit human approval each time; the script performs high-privilege changes. - If you want safer behavior, require the skill to provide: OS detection, a dry-run mode, an explicit confirmation prompt, rollback/uninstall instructions, and the missing config files and cost-analysis code.

Type: OpenClaw Skill Name: hostinger-vps-optimizer Version: 1.0.0 The skill bundle performs standard system administration tasks for VPS optimization and security hardening. The `scripts/optimize.sh` file uses `sysctl` for kernel tuning, installs Nginx, UFW, and Fail2ban via `apt`, and configures UFW to allow SSH. All actions align with the stated purpose in `SKILL.md` and do not exhibit any signs of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts against the agent. The commands are legitimate and commonly used in server setup scripts.
