# Mirror the canonical skills + slash commands into every NON-Claude plugin tree.
#
# Layout model (per each harness's plugin schema):
#   - Claude Code: the plugin root IS the repo root (marketplace.json `source: "./"`),
#     so its components live at the repo root — `skills/` and `commands/` — and the
#     `.claude-plugin/` directory holds ONLY the manifests (plugin.json,
#     marketplace.json) + statusline.sh. Claude IGNORES component dirs nested inside
#     `.claude-plugin/`. We therefore treat the repo-root `skills/` + `commands/` as
#     canonical and do NOT copy anything into `.claude-plugin/`.
#   - Codex / Cursor / OpenCode: each `<harness>-plugin/` directory is itself the
#     plugin root, so those trees get their own `skills/` + `commands/` copies.
#
# Idempotent. Run via the prek hook `sync-plugin-skills` or manually:
#   bash scripts/sync-plugin-skills.sh
