Nex Healthcheck

This package appears to be what it claims (a local health-check tool), but review and cautious deployment are advised: - Metadata mismatch: the registry marks Telegram env vars as required, but the code treats them as optional. Do not put production secrets into environments unless you intend to enable Telegram alerts. - SSH remote checks: the tool supports executing arbitrary commands on remote machines via SSH (ssh_cmd, remote docker/systemd). Only use that feature with hosts you control and with properly restricted SSH keys; untrusted targets can run unexpected commands. - Systemd timer: setup.sh can optionally install a user systemd timer to run checks periodically. Accept that only if you want a persistent background job; the installer prompts before enabling it. - Inspect and test before production: run setup.sh in a non-production or containerized environment first, inspect the created files (~/.nex-healthcheck, ~/.local/bin/nex-healthcheck), and verify behavior. - Code quality issues: there are minor bugs (e.g., SSL certificate check references the socket object after the with block) — consider reviewing/fixing or running tests before relying on expiry alerts. If you plan to use this skill: review the source (already included), avoid setting global/privileged tokens unnecessarily, restrict SSH access, and run the installer interactively so you can decline the systemd timer if undesired.
