Update

<objective> Check for GSD updates, install if available, and display what changed.

Routes to the update workflow which handles:

• Version detection (local vs global installation)
• npm version checking
• Changelog fetching and display
• User confirmation with clean install warning
• Update execution and cache clearing
• Restart reminder </objective>

<execution_context> @~/.claude/get-shit-done/workflows/update.md </execution_context>

<flags> - **--sync**: Sync managed GSD skills across runtime roots so multi-runtime users stay aligned after an update. Runs the sync-skills workflow (--from, --to, --dry-run, --apply flags supported). - **--reapply**: Reapply local modifications after a GSD update. Uses three-way comparison (pristine baseline, user-modified backup, newly installed version) to merge user customizations back. Runs the reapply-patches workflow. - **(no flag)**: Standard update — check for new version, show changelog, install. </flags> <process> Parse the first token of $ARGUMENTS: - If it is `--sync`: strip the flag, execute the sync-skills workflow (passing remaining args for --from/--to/--dry-run/--apply). - If it is `--reapply`: strip the flag, execute the reapply-patches workflow. - Otherwise: **Follow the update workflow** from `@~/.claude/get-shit-done/workflows/update.md`.

The update workflow handles all logic including:

1. Installed version detection (local/global)
2. Latest version checking via npm
3. Version comparison
4. Changelog fetching and extraction
5. Clean install warning display
6. User confirmation
7. Update execution
8. Cache clearing </process>
