Stitch video segments with ffmpeg concat, xfade, overlay, audio mux, and export settings, and trim a source into named clips at exact windows (trim_clips.py). Ships montage.py, a free montage assembler (python3 + ffmpeg, no keys). It takes a JSON EDL of clips and stills, normalizes them and hard-cuts them in order, burns captions from an SRT, a cue list or word timings, and lays a VO over a music bed that ducks under it, mastered to -14 LUFS.
Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'stitch-videos-ffmpeg' ] || [ -L ~/.agents/skills/'stitch-videos-ffmpeg' ]; then echo 'A skill folder named stitch-videos-ffmpeg already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gooseworks-ai/goose-skills' "$d" && git -C "$d" checkout --quiet 'df8298140d434a6363de0c265eb6af2e571d97a5' -- 'skills/video/stitch-videos-ffmpeg' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/video/stitch-videos-ffmpeg' ~/.agents/skills/'stitch-videos-ffmpeg' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'stitch-videos-ffmpeg' ~/.claude/skills/'stitch-videos-ffmpeg' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
