+# AITBC Systemd Git Workflow Skill
+
+## Description
+Expert skill for managing systemd service files using proper git workflow instead of scp operations. Ensures systemd configurations are always synchronized via git repository rather than direct file copying.
+
+## Core Principles
+
+### Git-Tracked Files Only
+- All systemd service files must be edited in `/opt/aitbc/systemd/` (git-tracked directory)
+- NEVER edit files directly in `/etc/systemd/system/`
+- NEVER use scp to copy systemd files between nodes
+
+### Symbolic Link Architecture
+- `/etc/systemd/system/aitbc-*.service` -> `/opt/aitbc/systemd/aitbc-*.service`
+- Symlinks ensure active systemd files always match repository
+- Changes in repository automatically reflected in active configuration
+
+## Standard Workflow
+
+### Local Changes
+1. Edit files in `/opt/aitbc/systemd/`
+2. Commit changes: `git add systemd/ && git commit -m "description"`
+3. Push to gitea: `git push`
+
+### Remote Sync (aitbc1)
+1. Pull changes: `git pull`
+2. Create/update symlinks: `/opt/aitbc/scripts/utils/link-systemd.sh`
+3. Reload systemd: `systemctl daemon-reload`
+4. Restart affected services: `systemctl restart aitbc-*`
+
+## Available Scripts
+
+### link-systemd.sh
+- Location: `/opt/aitbc/scripts/utils/link-systemd.sh`
+- Purpose: Creates symbolic links from `/etc/systemd/system/` to `/opt/aitbc/systemd/`
+- Usage: `/opt/aitbc/scripts/utils/link-systemd.sh`
+- Benefits: Automatic sync, no manual file copying needed
+
+### sync-systemd.sh
+- Location: `/opt/aitbc/scripts/sync/sync-systemd.sh`
+- Purpose: Copies repository files to active systemd (alternative to symlinks)
+- Usage: `/opt/aitbc/scripts/sync/sync-systemd.sh`
+- Note: Prefer link-systemd.sh for automatic sync
+
+## Common Issues
+
+### Git Conflicts on Remote Nodes
+**Symptom**: `git pull` fails with "local changes would be overwritten"
+
+**Resolution**:
+1. Discard local changes: `git reset --hard HEAD`
+2. Pull changes: `git pull`
+3. Re-run link-systemd.sh: `/opt/aitbc/scripts/utils/link-systemd.sh`
+
+### Broken Symlinks
+**Symptom**: Systemd service fails to load or uses old configuration
+
+**Resolution**:
+1. Verify symlinks: `ls -la /etc/systemd/system/aitbc-*`
+2. Re-create symlinks: `/opt/aitbc/scripts/utils/link-systemd.sh`
+3. Reload systemd: `systemctl daemon-reload`
+
+### SCP Usage Warning
+**Symptom**: Direct scp to `/etc/systemd/system/` breaks symlinks
+
+**Resolution**:
+1. Never use scp to `/etc/systemd/system/`
+2. Always use git workflow
+3. If scp was used, restore proper symlinks with link-systemd.sh
+
+## Verification Commands
+
+### Check Symlink Status
+```bash
+ls -la /etc/systemd/system/aitbc-*
+readlink /etc/systemd/system/aitbc-blockchain-node.service
+```
+
+### Verify Git Status
+```bash
+git status
+git diff systemd/
+```
+
+### Check Service Configuration
+```bash
+systemctl cat aitbc-blockchain-node.service
+```
+
+## Best Practices
+
+1. **Always edit in git-tracked directory**: `/opt/aitbc/systemd/`
+2. **Commit before pushing**: Ensure changes are properly committed
+3. **Pull before link-systemd.sh**: Ensure repository is up-to-date
+4. **Test locally first**: Verify changes work before syncing to remote
+5. **Document changes**: Use descriptive commit messages
+6. **Monitor logs**: Check service logs after changes
+7. **Run as root**: No sudo needed - we are root on both nodes
+
+## Memory Reference
+See memory entry `systemd-git-workflow` for detailed workflow documentation (no sudo needed - we are root on both nodes).
