+# OpenClaw Auto-Updater
+
+Run **scheduled updates** for OpenClaw and installed skills using cron messages (no scripts required). Focus: safe scheduling, predictable output, and minimal manual work.
+
+## What it does
+
+- Runs OpenClaw updates on a fixed schedule
+- Updates all installed skills via ClawHub
+- Sends a concise, readable summary (updated / unchanged / failed)
+
+## Setup (daily updates)
+
+**Daily at 03:30 Europe/Berlin**:
+```bash
+openclaw cron add \
+  --name "OpenClaw Auto-Update" \
+  --cron "30 3 * * *" \
+  --tz "Europe/Berlin" \
+  --session isolated \
+  --wake now \
+  --deliver \
+  --message "Run daily auto-updates: 1) openclaw update --yes --json 2) clawdhub update --all 3) report versions updated + errors."
+```
+
+### Weekly (Sunday 04:00)
+```bash
+openclaw cron add \
+  --name "OpenClaw Auto-Update (Weekly)" \
+  --cron "0 4 * * 0" \
+  --tz "Europe/Berlin" \
+  --session isolated \
+  --wake now \
+  --deliver \
+  --message "Run weekly auto-updates: openclaw update --yes --json; clawdhub update --all; summarize changes."
+```
+
+## Safer modes
+
+**Dry run (no changes):**
+```bash
+openclaw cron add \
+  --name "OpenClaw Auto-Update (Dry)" \
+  --cron "30 3 * * *" \
+  --tz "Europe/Berlin" \
+  --session isolated \
+  --wake now \
+  --deliver \
+  --message "Check updates only: openclaw update status; clawdhub update --all --dry-run; summarize what would change."
+```
+
+**Core only (skip skills):**
+```bash
+openclaw cron add \
+  --name "OpenClaw Auto-Update (Core Only)" \
+  --cron "30 3 * * *" \
+  --tz "Europe/Berlin" \
+  --session isolated \
+  --wake now \
+  --deliver \
+  --message "Update OpenClaw only: openclaw update --yes --json; summarize version change."
+```
+
+## Summary format (recommended)
+```
+🔄 OpenClaw Auto-Update
+
+OpenClaw: 2026.2.1 → 2026.2.2 (OK)
+Skills updated: 3
+Skills unchanged: 12
+Errors: none
+```
+
+## Troubleshooting
+
+- If updates fail, include the error in the summary.
+- Schedule off-hours; updates may restart the gateway.
+- Use explicit timezones to avoid surprises.
