## Command Execution Principles
### Security
- ❌ `exec(userInput)`, `shell("rm " + userFile)`
- ✅ Argument lists (no shell string concat), validate/sanitize all args
- Never run as root/admin without explicit human approval. Elevated perms required → STOP and request auth.
- Least-privilege service accounts
### Portability
- Use language stdlib over shell commands (file I/O APIs instead of cat/cp/mv)
- Test on all target OS (path joining functions, not / concatenation)
### Error Handling
- Check exit codes (non-zero = failure)
- Capture + log stderr
- Set timeouts for long-running
- Handle "command not found" gracefully
### Checklist
- [ ] User input sanitized before commands
- [ ] Arguments as lists (no shell concat)
- [ ] Minimum permissions
- [ ] Exit codes checked
- [ ] Timeouts set
- [ ] stderr captured + logged
