PL role sub-skill — environment doctoring. Loaded ONLY by the pl core via its routing table; NEVER auto-load from context, never invoke directly.
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.
What the file says
# PL · Env — environment self-service
Scripts named below run as `bash "${PL_SKILL_DIR}/scripts/<name>.sh" ...`, where `PL_SKILL_DIR` is the
absolute path of the `pl` skill directory; set it in the same Bash call.
Sub-skill of the PL role. The pl core skill invokes this EXPLICITLY on any
environment doubt: a "not available / missing / down" claim, a restart wish, a
VM/host question, or before opening an evaluation or end-to-end run. Canonical scripts:
the pl skill's `scripts/`. Read the host/VM registry from `${SNO_ROSTER_FILE:-}`;
when unset, report "no roster configured" and continue. The TSV columns are
name, address, kind, purpose, and check; no machine inventory ships with the skill.
Use the repo's documented service-address source when one exists.
Read `${SNO_SECRETS_CMD:-}` for an optional secrets wrapper: one executable path
that accepts a command and its arguments, injects secrets, and preserves its exit status.
When unset, report "no secrets wrapper configured" and continue.
Read `${OPENAI_BASE_URL:-}` for model connectivity; when unset, report
"using the harness's own endpoint" and continue.

How to install
mdr add sno-ai/sno-station-skills/pl-env@sha256:6cfbf4795d499e8bThe line at the top of this page pins the label git:20261001.8e39faf, 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.
