Skill: Reprocess With Contact Sheets

Bring a library that was analyzed under the old pipeline (visual_transcripts, no contact sheets) onto the current one (audio transcript + contact sheet + summary). Audio transcripts and any cuts/plans the user has already built are preserved — only the visual layer is rebuilt.

Step 1 — Pick the library

If the user named a library, use it. If not, list candidates with ruby lib/buttercut/library.rb recent and use AskUserQuestion to pick one.

Verify it exists and read the snapshot:

ruby lib/buttercut/library.rb <name> exists
ruby lib/buttercut/library.rb <name> summary

Run any schema migrations from AGENTS.md → Critical Principles before touching anything else.

Step 2 — Confirm with the user
