Create a new editing-style skill from 2-3 reference reels of one creator or style (e.g. "make me a skill that edits like @creator"). Downloads the reels, measures them frame by frame, has one agent break down each reel, merges the breakdowns into a style guide plus a measurable style spec, clones the proven editing engine into a new /<style>-edit skill, then locks the style with a match score, pixel font matching, a golden recreation test, one critic round and the user's ear check. Free local tools only. Use when someone says "/new-edit-style", "make an edit style skill", "copy this creator's editing style", "I want to edit like X", or drops several reels from one creator and asks for their style.

/new-edit-style

Reference reels in, a locked /<style>-edit skill out, so every edit made with it looks like the references. This is the process that built /kallaway-edit, written down and sharpened. The person using it is usually NOT technical: plain English, one short message per step, never make them touch code.

SK = ${CLAUDE_SKILL_DIR}, this skill's folder. ENGINE = ${CLAUDE_SKILL_DIR}/../kallaway-edit, the proven editing skill it builds on (it carries the setup wizard, transcription, cutting, cut-out, sound, build, render and QA). Never write into SK or ENGINE: an update replaces both. DATA = $HOME/.claude-video-editor, the editor's own folder that survives updates (settings, Python, sound effects, font cache). ROOT = the project folder (projectRoot in DATA/config.json). Run every script through one of these, exactly as written, so it finds the user's settings: PY = VIDEO_EDITOR_DATA="$HOME/.claude-video-editor" "$HOME/.claude-video-editor/venv/bin/python" -I SYS = VIDEO_EDITOR_DATA="$HOME/.claude-video-editor" python3 -I (before setup has run) STYLE = short kebab-case name ("kallaway"). SDIR = ROOT/references/<STYLE>/. WORK = ROOT/work/new-edit-style/<STYLE>/ (progress PNGs go in WORK/progress/, numbered).

Hard rules

  • Free tools only (ffmpeg, Python, faster-whisper, HyperFrames, OFL fonts). No paid APIs, no sign-ins. Download reference links logged out (yt-dlp --no-cookies); never use a browser's cookies.
  • Never touch the user's original files; never delete anything (move old versions to ROOT/archive/).
  • Never run npx hyperframes init or npx hyperframes skills; nothing may be added to ~/.claude/skills or ~/.agents/skills.
  • Never present a guess as measured, or a sound as heard. Agents can't hear; the user's ear check decides.
  • Copying an editing STYLE is fine; never copy the creator's footage, logos, music or text into an edit.
  • Sub-agents: one per reference reel for the breakdowns (Sonnet is fine), at most 3 at once, briefed with references/breakdown-brief.md. Everything that needs judgement or eyes, you do yourself.

Workflow

0. Setup (first time only)

If DATA/config.json lacks "setupComplete": true, run the editor's setup wizard first: invoke the kallaway-edit skill with setup (or read ENGINE/SKILL.md step 0, where ${CLAUDE_SKILL_DIR} means ENGINE and $HOME/.claude-video-editor means DATA): Claude Code check, tool check, project folders, install. If ENGINE is missing, say: "This needs the kallaway-edit skill installed next to it (it carries the editing engine). Reinstall both from https://github.com/learnaiwithhugo/video-editor-skills, then run /new-edit-style again." Then stop. This skill also needs yt-dlp (it downloads the reference reels), so always check with SYS "ENGINE/scripts/setup.py" --check --for new-edit-style, on the first run and later ones. If yt-dlp is missing, give the user its fix line (brew install yt-dlp, pasted in the Terminal app), wait until they say it's done, and check again.

1. Intake (~2 min)

Ask, in one message: "Send me 2 or 3 reels (links or files) from ONE creator whose editing you want to copy, ideally your favourite edits of theirs, and a short name for the style." 3 is best: rules come from what all of them share. Then: SYS "SK/scripts/fetch.py" STYLE "ROOT" <link or file> ... -> SDIR/STYLE-1.mp4 ... Say: "Got them. Measuring every frame now (about 2 minutes)."

2. Prep, all scripted (~30 s per reel)

PY "SK/scripts/prep.py" "SDIR" SDIR/STYLE-*.mp4 Per reel in SDIR/prep/<reel>/: word-timed transcript, every-frame cut scan, 4 fps contact sheets with times, full-size stills, spectrogram, stereo sound-effect hits, loudness, and fingerprint.json (the measured style numbers). Plus SDIR/style-check.png and SDIR/style-spec.json. Look at style-check.png now. If one reel clearly doesn't share the others' look (different layout, captions, colours), tell the user and ask for a replacement before spending agents. Copy it to WORK/progress/01-style-check.png.

3. Breakdowns, one agent per reel, in parallel (~15 min)

Fill references/breakdown-brief.md once per reel and launch them in one message. Each writes SDIR/prep/<reel>/edit-log.md. While they run, do step 4's font match.

4. Font match (~20 s)

PY "SK/scripts/font_match.py" SDIR/STYLE-1.mp4 SDIR/prep/STYLE-1/transcripts/STYLE-1.words.json "SDIR/font" Look at font-match.png: the winner must visibly match. Run it on a second reel if the top two are within 0.01. (Kallaway: Archivo 800 at -0.045 em scored 0.773, above Helvetica Neue Bold's 0.759.)

5. Merge into the style guide (you, ~10 min)

Follow references/merge-guide.md: consensus rules, measured numbers, a key-frames sheet you look at yourself, and the filming section. Output SDIR/STYLE-style-guide.md + SDIR/STYLE-key-frames.png. Open the key-frames sheet for the user and give them the one-paragraph summary.

6. Make the style skill (~2 min + your rewrite, ~30 min)

SYS "SK/scripts/make_style_skill.py" STYLE "SDIR" --title "Display Name" It clones the proven engine (ENGINE, found next to this skill) into ROOT/.claude/skills/STYLE-edit/: a project skill in the user's own video folder, never in the global skills folder, so updates never touch it. The copy shares DATA (no second install). It adds the match tools (scripts/match/), writes style.json from the measured spec, and prints the checklist of style files to rewrite from the style guide (SKILL.md style rules, style-rules.md, graphics-recipes.md, sound-map.md, filming-guide.md, the kit CSS/JS, and build.py's layouts only if the style has different layouts). Rewrite every item on the list. Engine scripts stay untouched unless a layout needs it.

7. Lock the style (~45-60 min)

Follow references/lock.md: a test edit on the user's footage -> match score -> fix -> golden recreation of a reference window -> fix -> one critic round -> ear check -> sign-off. Log every number in STYLE-edit/references/lock-log.md.

8. Deliver

Tell the user: the new command (/STYLE-edit, available whenever Claude Code is opened in ROOT; if it doesn't show up yet, restart Claude Code there), what it does in one paragraph, the match score and golden numbers, how to film for it (3-4 bullets from the filming section), and what still doesn't match.

Timings (on an M4 Pro Mac, 3 reels of ~1.5 min)

fetch 1 min · prep 1.5 min · breakdowns 15-18 min (parallel) · font match 20 s · merge 10 min · make skill 2 min + rewrite 30 min · lock 45-60 min. About 2 hours end to end, mostly agents and renders.

Files

scripts/: fetch.py, prep.py, fingerprint.py (measure / spec / score), font_match.py, golden.py, make_style_skill.py, engine.py (finds ENGINE). references/: breakdown-brief.md, merge-guide.md, lock.md. templates/: style-rules.md, graphics-recipes.md, lock-log.md (copied into new style skills).

Individual skills in this repo

This repo contains 3 individual skills — each has its own dedicated page.

learnaiwithhugo/video-editor-skills

Style Studio. Walks a creator (usually non-technical) through building their OWN video editing style on an interactive page in their browser - their colours and font, reference reels they love broken down frame by frame, then rounds of real animated options (captions, accent and intro text, zooms, diagrams, logos, split screen, tool talk, sound effects) they mark Keep / Maybe / Drop, plus Shine, Zoom and Shadow labs with Lock buttons. Ends with a STYLE.md guide and locked settings that /edit-my-video uses. Use whenever someone says "/build-my-style", "build my style", "make my editing style", "style studio", "I want my own edit style", "copy the editing style of these reels", "make my brand style for videos", sends reels they want their edits to look like, or comes back to carry on their style (rounds, labs, sounds). Also the STYLE keyword giveaway.

learnaiwithhugo/video-editor-skills

Edit raw talking-head clips into a finished vertical Instagram reel in the creator's OWN style, read from a style folder made by build-my-style (STYLE.md, locked shine/zoom/shadow, picked sound effects). Picks the last clean take of every line, shows a storyboard page first (a still per beat, A/B/C options on the key beats, Approve/Change and notes), optionally renders short variations of key moments to pick from, then builds the full edit in HyperFrames, reviews its own render, and turns every note the user gives into a dated rule in their STYLE.md so the next edit is better. Free local tools only. Use whenever someone says "/edit-my-video", "edit my video", "edit these clips", "make this into a reel in my style", "storyboard this edit", drops a folder of raw clips and wants an edit, or gives notes on an edit this skill made ("I don't like the zoom", "make the logos bigger").

learnaiwithhugo/video-editor-skills

Edit a raw talking-head clip into a finished Instagram reel in Kallaway's editing style (black dotted stage with one live diagram per idea, rounded face card with the head popping out over its edge, one-word white captions, red as the only accent, hard cuts on word onsets, a real sound effect on every animation, optional quiet ducked background music). Free local tools only (ffmpeg, Whisper, HyperFrames). Use when someone says "/kallaway-edit", "edit this like Kallaway", "make this reel in the Kallaway style", or drops raw clips and asks for a Kallaway-style edit.
