Upgrade Process

Step 1: Check for Updates

Read the current version from CLAUDE.md (look for "System Version:" line).

Compare with the upstream repo. If using git:

bash
git fetch origin
git log HEAD..origin/main --oneline

If not a git repo or no remote, inform user they need to download the latest vault-template/ manually.

Step 2: Create Backup

Before any changes, create a timestamped backup:

bash
BACKUP_DIR=".backup/upgrade-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$BACKUP_DIR"
cp -r .claude "$BACKUP_DIR/"
cp CLAUDE.md "$BACKUP_DIR/"
cp -r Templates "$BACKUP_DIR/" 2>/dev/null

Tell the user: "Backup created at $BACKUP_DIR"

Step 3: Diff Review

For each system file that differs from upstream:

1. Show a summary of what changed (additions, removals, modifications)
2. Ask user to confirm: "Apply this update? (yes/skip/stop)"
3. If yes: apply the change
4. If skip: leave this file unchanged
5. If stop: halt the upgrade (backup remains, partial changes preserved)

Step 4: Apply Changes

For each confirmed file:

• Copy the new version from upstream
• For CLAUDE.md: merge carefully — preserve user customizations (Personal Mission, Current Focus sections) while updating system sections (Skills table, version number)
• For settings.json: merge — add new permissions/hooks, preserve existing customizations

Step 5: Post-Upgrade

1. Make hook scripts executable: chmod +x .claude/hooks/*.sh
2. Show summary of changes applied
3. Update version in CLAUDE.md
4. Suggest running /onboard to reload context

Check Mode (/upgrade check)

When invoked with "check":

1. Compare system files against upstream
2. List files that would be updated with brief change description
3. Show version numbers (current → available)
4. Do NOT make any changes
5. Suggest running /upgrade to apply
