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

This is destructive. Tell the user, in plain terms, what will happen:

• Contact sheets, summaries, and any legacy visual_*.json transcripts will be deleted.
• Audio transcripts are kept — no re-transcription.
• cuts/, plans/, and library metadata (footage_summary, user_context, editor, etc.) are untouched.

Use AskUserQuestion with a clear yes/no before proceeding. Don't reset on assumption.

Step 3 — Backup first

Always back up before the reset — this step is mildly risky and a fresh archive is the cheapest insurance. Run the backup-library skill against the chosen library and wait for it to finish before touching anything else. If the backup fails, stop and surface the error; don't proceed to the reset.

Step 4 — Reset

One command wipes contact sheets, summaries, and legacy visual transcripts and clears the matching fields on every clip:

ruby lib/buttercut/library.rb <name> reset_all_except_audio_transcripts

If a clip is missing its audio transcript (some libraries predate even that), the analyze-video skill's footage-processing step (transcripts) will fill it in on the next step — no special handling here.

Step 5 — Re-run analysis

Hand off to skills/analyze-video/SKILL.md end-to-end. Skip the audio-transcript pass for any clip that already has transcript set in the snapshot; run contact sheets and summaries for every clip. The confirm-footage-understanding pass is still worth doing — the new summaries may surface details the old visual_transcripts missed.

Verify readiness before reporting done:

ruby lib/buttercut/library.rb <name> ready
