+## Exit Codes
+
+opencli follows Unix `sysexits.h` conventions so it integrates naturally with shell pipelines and CI scripts:
+
+| Code | Meaning | When |
+|------|---------|------|
+| `0` | Success | Command completed normally |
+| `1` | Generic error | Unexpected / unclassified failure |
+| `2` | Usage error | Bad arguments or unknown command |
+| `66` | Empty result | No data returned (`EX_NOINPUT`) |
+| `69` | Service unavailable | Browser Bridge not connected (`EX_UNAVAILABLE`) |
+| `75` | Temporary failure | Command timed out — retry (`EX_TEMPFAIL`) |
+| `77` | Auth required | Not logged in to target site (`EX_NOPERM`) |
+| `78` | Config error | Missing credentials or bad config (`EX_CONFIG`) |
+| `130` | Interrupted | Ctrl-C / SIGINT |
+
+```bash
+opencli spotify status || echo "exit $?"   # 69 if browser not running
+opencli github issues 2>/dev/null
+[ $? -eq 77 ] && opencli github auth       # auto-auth if not logged in
