The instructions your model reads when the skill loads.
CLI for editing CapCut / JianYing drafts through a version-aware store. v0.11 detects and synchronizes readable timelines across draft_content.json, draft_info.json, draft_meta_info.json, and template-2.tmp.
~/Movies/CapCut/User Data/Projects/com.lveditor.draft/<project>/%LOCALAPPDATA%\CapCut\User Data\Projects\com.lveditor.draft\<project>\Any recipe involving more than one capcut call, any arithmetic, or any branching ships as a parameterised shell script in scripts/. Claude invokes the script with inputs; the script runs a fixed sequence. If a recipe can be a script, it must be a script — not a narrative in references/.
references/workflows.md documents which script to call and why, never a reconstructable sequence.
Start broad, drill into what you need. Never dump full project JSON.
