<arguments>$ARGUMENTS</arguments>

The text inside `<arguments>` is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

<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>

<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.
• **--interactive[=exceptions|all]** (with `--reapply` only): show each user edit next to the stock text with a recommended disposition and wait for a keep / retire / rewrite decision per edit. `all` shows every edit; `exceptions` (bare `--interactive`) shows only edits upstream adopted, partly adopted, reworded around, or orphaned, and keeps the rest. Without it, `--reapply` behaves exactly as before.
• **--next** (alias **--rc**): Target the `@next` RC dist-tag instead of `@latest` so you can install or refresh a release candidate (e.g. `1.4.0-rc.1`) through the normal update flow — scope/runtime detection, changelog preview, custom-file backup, and cache clearing all still apply. Omitting it keeps targeting `@latest` (no change). See ADR #660 for the RC channel.
• **(no flag)**: Standard update — check for new version, show changelog, install.

</flags>

<process> If the arguments contain `--interactive` (bare or with a value) but not `--reapply`, STOP with: `--interactive applies only to --reapply (for example: /gsd:update --reapply --interactive=all)`. Do nothing else.

Parse the first token of the `<arguments>` block:

• 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, passing the remaining arguments (for example `--interactive=all`) to it.
• Otherwise (including `--next` / `--rc`): execute the update workflow end-to-end, passing the `<arguments>` block through so the workflow's parse_update_channel step can select the release channel.

</process>
