# dev-sync.sh — copy this working tree into the installed /watch plugin cache so
# local edits are picked up by Claude Code without publishing a release.
#
# The install path is resolved from ~/.claude/plugins/installed_plugins.json, so
# it follows version bumps automatically. Override it by passing a path as $1 or
# setting WATCH_INSTALL_PATH. Pass --dry-run to preview without writing.
#
# Usage:
#   ./dev-sync.sh                 # sync into the resolved install path
#   ./dev-sync.sh --dry-run       # show what would change
#   ./dev-sync.sh /some/other/dir # sync into an explicit path
