Lists CapCut projects found in the local draft store, with folder, path and last-modified time.

Reads a project: duration, resolution, tracks, subtitles as readable text, and which material buckets are populated. Read-only.

Verdict (ok / warn / refuse) before any modification: CapCut vs JianYing, upstream write guard, whether the editor is running, storage-mirror agreement, existing lint errors, and availability of ffmpeg/ffprobe. Run this before writing.

Applies one style — outline, shadow, background plate, opacity, size, colour, weight — and optionally an entrance animation to every caption at once. This is the job editors otherwise do by hand on every video. Presets: bold-outline, boxed, accent. Animation slugs come from 'capcut enums --text-intros' (typewriter, pop-up, glitch, fade-in, …). NOT supported upstream: font family and on-screen position — those stay manual. Requires CapCut to be closed; use dryRun to preview.

Turns an SRT file — or raw SRT text — into a text track with one segment per cue, styled in the same pass. Presets: bold-outline, boxed, accent. Keyword highlighting colours chosen words inside every caption (whole-word, case-insensitive), which editors otherwise do by hand. Byte offsets are correct for Cyrillic, Uzbek and emoji. Requires CapCut to be closed.

Renders an animated overlay with a real alpha channel (ProRes 4444) using Remotion — motion graphics CapCut cannot author itself. Returns the file path; place it with add_overlay. Requires ffmpeg. Rendering takes tens of seconds.

Adds an already-rendered clip to a CapCut project on its own track. Requires CapCut to be closed.

Renders a transparent overlay and adds it to the project at the given time. The common case — use render_overlay separately when the same graphic is reused across projects.
