Update Nexus
Purpose: Sync system files from the upstream Nexus repository while protecting user data Trigger: "update nexus", "sync nexus", "get updates", "check for updates" Duration: 1-2 minutes
What This Does
Updates these system files from upstream:
00-system/- Core framework, skills, documentationCLAUDE.md- Entry pointREADME.md- Project readme
Protects these user folders (NEVER touched):
01-memory/- Your goals, learnings, config02-projects/- Your projects03-skills/- Your custom skills04-workspace/- Your files.env,.claude/- Your secrets and settings
Workflow
Step 1: Check for Updates
Run the update check:
python 00-system/core/nexus-loader.py --check-updateParse the JSON response:
- If
checked: falsewith error → Display error, exit gracefully - If
update_available: false→ Display "Already up-to-date!", exit - If
update_available: true→ Continue to Step 2
Step 2: Show What Will Change
Display to user:
UPDATE AVAILABLE
Current version: {local_version}
New version: {upstream_version}
Files to update ({changes_count}):
{list changed_files, max 20}
PROTECTED (will NOT be touched):
- 01-memory/ (your goals & config)
- 02-projects/ (your projects)
- 03-skills/ (your custom skills)
- 04-workspace/ (your files)Step 3: Confirm with User
Ask: "Proceed with update? (yes/no)"
- If no → Exit with "Update cancelled"
- If yes → Continue to Step 4
Step 4: Perform Sync
Run the sync command:
python 00-system/core/nexus-loader.py --sync --forceParse the JSON response:
- If
success: false→ Display error message, suggest fixes - If
success: true→ Continue to Step 5
Step 5: Display Results
On success, display:
UPDATE COMPLETE!
{local_version} → {upstream_version}
Updated paths:
{list files_updated}
Backup saved to: {backup_path}
To commit this update:
git add . && git commit -m "Update Nexus to v{upstream_version}"Error Handling
| Error | User Message |
|---|---|
| "Not a git repository" | "This folder isn't a git repo. Initialize with: git init" |
| "Could not reach upstream" | "Can't connect to GitHub. Check your internet connection." |
| "Uncommitted changes detected" | "You have uncommitted changes. Commit them first:\n git add. && git commit -m 'Save changes'" |
| "Could not read upstream version" | "The upstream repo might not be set up correctly. Check the URL in user-config.yaml" |
Advanced: Dry Run
To preview changes without applying:
python 00-system/core/nexus-loader.py --sync --dry-runThis shows what WOULD change, but doesn't change anything.
Notes
- Backup: Before any sync, your current system files are backed up to
.sync-backup/{timestamp}/ - Safe: User data folders are NEVER in the sync paths - they cannot be touched
- Upstream Remote: Automatically added on first use (named "upstream")
- Default URL: https://github.com/beamanalytica/Nexus-v4.git (can override in user-config.yaml)
