name: bookmorph-magic description: Orchestrate a book-to-content workflow when the user wants to turn one book into multiple content assets such as video, audio, and cover images for an episode or campaign. Use for requests like “制作 ep38 内容”, “turn this book into an episode package”, or “generate multi-format content from a book”. This is a publishable template skill: it defines the adapter contracts for selecting a source book, generating longform media, generating covers, and bundling outputs.

BookMorph Magic

Use this skill as a publishable template for book-to-content orchestration. It is not a private, fixed workflow.

What this template does

• Takes one book or one episode-style request
• Produces a package of multi-format content
• Bundles the final outputs into a stable episode directory with a manifest

Typical outputs:

• one video
• one audio file
• three cover images (3:4, 4:3, 1:1)
• one manifest.json

Important constraints

• This is a template, not a turnkey SaaS workflow.
• To run end to end, you must provide 3 adapters:
  • book selector
  • longform content generator
  • cover generator
• If you already have existing skills or scripts for those adapters, wire them to the contracts in references/integration-template.md.

Inputs

• A book file path, or
• A request containing one episode identifier such as ep38, EP38, episode 38, or 第38期

Output contract

• Output root is configurable
• Episode directory prefix is configurable; default is episode-
• Stable output filenames:
  • epNN-video.<ext>
  • epNN-audio.<ext>
  • epNN-cover-3x4.<ext>
  • epNN-cover-4x3.<ext>
  • epNN-cover-1x1.<ext>
  • manifest.json

Workflow

1. Parse the episode identifier with scripts/episode_bundle.py parse-episode.
2. Create or reset the target episode directory with prepare-dest.
3. Run your book selector adapter until it chooses exactly one source book.
4. Run your longform content generator adapter to produce a video and an audio output.
5. Run your cover generator adapter to produce 3:4, 4:3, and 1:1 images.
6. Run bundle to copy the final artifacts into the episode directory and write manifest.json.

Adapter requirements

Book selector

Must return enough information to identify one selected source:

• book title
• author
• local source file path
• selection round or attempt count
• optional selector checkpoint path

Longform content generator

Must return:

• video file path
• audio file path
• attempt count
• optional generator checkpoint path

Cover generator

Must return:

• image path for 3:4
• image path for 4:3
• image path for 1:1
• attempt count
• optional prompt archive path
• optional generator checkpoint path

Failure rules

• If the episode number cannot be parsed, fail immediately.
• If no source book can be selected, stop and write a failed manifest.
• If longform media is incomplete, stop and write a failed or partial manifest.
• If any required cover image is missing, stop and write a failed or partial manifest.
