Documentación

/promo-clip:upgrade

Read ${CLAUDE_PLUGIN_ROOT}/skills/promo-clip/protocol.md first. A video keeps its own engine copy so it never breaks when the plugin changes; this stage pulls in the plugin's engine on request.

  1. Compare versions: node "${CLAUDE_PLUGIN_ROOT}/engine/tools/cli.mjs" status --project V --json → engine (the video's) vs toolsEngine (the plugin's). Equal → nothing to do; say so and stop.
  2. Before: node V/tools/cli.mjs stills V/.work/upgrade/before --scenes --format <primary> --size 720p --png --project V.
  3. Upgrade: node "${CLAUDE_PLUGIN_ROOT}/engine/tools/cli.mjs" upgrade --project V — replaces js/, tools/, index.html, VERSION and the bundled fonts; keeps scenes, timeline, theme, manifest, providers.json and assets; marks scenes stale; the old engine is kept in V/.work/engine-<old version>/.
  4. After: the same stills command into V/.work/upgrade/after (now with the new engine).
  5. Compare: node "${CLAUDE_PLUGIN_ROOT}/tests/pixel-diff.mjs" V/.work/upgrade/after V/.work/upgrade/before --out V/.work/upgrade/diff --project V. Read the stills that differ.

Report: old → new version, which scenes changed and how they look. If a scene broke (it throws in build, or a still is clearly wrong), show the error and offer to fix the scene, or to roll back: copy V/.work/engine-<old>/js, tools (keep tools/node_modules), index.html and VERSION back and set promo.json engine to the old version. /promo-clip then re-runs the stale stages (scenes → formats → export).
