 ## Rules
 - `lib/__init__.py` must be bare package marker (comment only, NO eager imports)
 - After edits: run `bash scripts/sync.sh` to deploy

+- Git remote: origin = public (`mvanhorn/last30days-skill`)

+## Beta channel
+
+Experimental changes get tested on `mvanhorn/last30days-skill-private`, which installs as a parallel `/last30days-beta` slash command. Beta-only changes never ship to public without a review PR here. Workflow guide lives at `BETA.md` in the private repo. Plan that established this setup: `docs/plans/2026-04-17-005-feat-beta-skill-from-private-repo-plan.md`.
