+# Daily Briefing
+
+Generate a concise morning briefing. This skill demonstrates how
+Claude Code can replicate OpenClaw's HEARTBEAT.md autonomous tasks.
+
+## Steps
+
+1. Search for today's top AI news (3 items max)
+2. Search for any breaking tech news
+3. Summarize in a structured briefing
+
+## Output format
+
+```
+## Morning Briefing - [date]
+
+### Top AI News
+- [headline]: [one-sentence summary] ([source])
+- ...
+
+### Action Items
+- [anything that needs attention today]
+
+### Weather
+[Not available without location API - add your own MCP server]
+```
+
+## Automation
+
+To run this daily, see `automation/README.md` for cron and
+launchd setup instructions. You can schedule this with:
+
+```bash
+claude -p "Run /daily-briefing" --output-format text
+```
