## Error

```text
--dangerously-skip-permissions cannot be used with root/sudo privileges for security reasons
```

## Symptom
A cron/systemd job that runs `claude -p "..." --dangerously-skip-permissions` (or `--permission-mode bypassPermissions`) exits immediately; the job log contains only:
```
--dangerously-skip-permissions cannot be used with root/sudo privileges for security reasons
```

## Cause
Claude Code refuses permission bypass when the process runs as root.

## Fix
Preferred: run the agent as an unprivileged user that owns its working directory.
```bash
useradd -m agent
chown -R agent:agent /srv/agent-work
# crontab -u agent -e
*/10 * * * * cd /srv/agent-work && claude -p "$(cat task.md)" --dangerously-skip-permissions
```
Remember to `chown -R` again after copying files in as root (files rsynced from a Mac arrive as uid 501 and the agent cannot write them).


## Verify
The heartbeat job ran normally under the unprivileged user.

## Notes
Do not run unattended agents as root; a dedicated low-privilege user also limits what a mistaken command can damage.
