#
# sync-to-codex-plugin.sh
#
# Sync this superpowers checkout → prime-radiant-inc/openai-codex-plugins.
# Clones the fork fresh into a temp dir, rsyncs upstream content, regenerates
# the Codex overlay file (.codex-plugin/plugin.json) inline, commits, pushes a
# sync branch, and opens a PR.
# Path/user agnostic — auto-detects upstream from script location.
#
# Deterministic: running twice against the same upstream SHA produces PRs with
# identical diffs, so two back-to-back runs can verify the tool itself.
#
# Usage:
#   ./scripts/sync-to-codex-plugin.sh                              # full run
#   ./scripts/sync-to-codex-plugin.sh -n                           # dry run
#   ./scripts/sync-to-codex-plugin.sh -y                           # skip confirm
#   ./scripts/sync-to-codex-plugin.sh --local PATH                 # existing checkout
#   ./scripts/sync-to-codex-plugin.sh --base BRANCH                # default: main
#   ./scripts/sync-to-codex-plugin.sh --bootstrap --assets-src DIR # create initial plugin
#
# Bootstrap mode: skips the "plugin must exist on base" check and seeds
# plugins/superpowers/assets/ from --assets-src <dir> which must contain
# PrimeRadiant_Favicon.svg and PrimeRadiant_Favicon.png. Run once by one
# team member to create the initial PR; every subsequent run is a normal
# (non-bootstrap) sync.
#
# Requires: bash, rsync, git, gh (authenticated), python3.
