Skill: Cut

This skill builds a timeline from a library.

1. Confirm the library and pre-flight readiness

You need a library before any cut work. If one is already in context from the current conversation, use it. Otherwise show recent libraries (ruby lib/buttercut/library.rb recent 5) and let the user pick.

Once the library name is known, check if the library is ready (all footage processed).

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

Exit code 0 means the library is ready for cut building (Library.ready? is the source of truth on what that means — don't re-derive the criteria here). If it exits non-zero, stop. Run ruby lib/buttercut/library.rb <name> summary to surface the incomplete clips and tell the user the library needs to finish processing (point them at the process-library skill). Don't try to cut around missing clips.

2. Determine Task Type

Ask the user with AskUserQuestion tool if available. Otherwise ask in text in this order.

Ask plainly. "Roughcut" in the user's opening request is trained vocabulary, not a confirmed choice — present the options and let them pick. Don't explain to the user why you're asking, and don't apologize for re-asking; the question stands on its own.
