Zero-dependency Bash environment health check for Linux, macOS, containers, and K8s pods. Reports OS, current user, Node.js, Python3, basic tools (git/curl/jq/make/docker) with paths and versions, network (hostname, IP, inferred subnet), container/K8s detection with a configurable env-var probe, workdir and git status, optional config-file check, and PVC remount detection (device-number plus watch-dir count snapshot diff to catch silent K8s PersistentVolume reattach to a fresh disk).…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

Pure `bash`. No Python, no npm, no third-party packages. Works on macOS, Linux, and inside containers.
## Compatibility
| Platform | Status |
|---|---|
| Linux (any distro) | ✅ Full |
| macOS (bash 3.2.57+ default) | ✅ Full — uses `${!var}` indirect expansion (no eval; bash 2.0+) |
| Windows (WSL / WSL2) | ✅ Full (effectively Linux) |
| Windows (Git Bash / MSYS / Cygwin) | ⚠️ Partial — OS/user/tools/network checks work; cgroup container detection and PVC monitoring are skipped (Linux-only kernel features) |
| Windows (PowerShell / cmd) | ❌ Not supported by design (bash script) |
| Agent Platform | Status |
|---|---|
| Claude Code | ✅ Standard SKILL.md, drops in |
| Codex | ✅ Same |
| OpenClaw | ✅ Native format |
| Cursor / Cline / others | ✅ Generic Markdown + bash, no platform hooks |

How to install
mdr add songhonglei/better-agent-skills/hello-env@sha256:fed9e438e99c5c5bThe line at the top of this page pins the label git:20261017.7e50876, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
