Suggest Sfx

suggest-sfx

Step 4 of the AI Video Editor pipeline — the SFX pass. Analyze a video's beats + narration and propose tasteful sound effects synced to them, drawing from (and growing) a shared, reusable SFX library, then render an SFX-mixed audition preview. Use when the user wants to "add SFX / sound effects", "suggest sfx", "score the transitions", "sound-design this beat", generate/source sound effects, build or extend the sfx library/catalog, author or audit a sfx-plan, or mix SFX over a video-N preview in this repo. Covers reading timeline + edited-transcript + brand §10, the library-first flow, generating misses with the ElevenLabs Sound Effects API, the per-video sfx-plan.json, the hard user-audit gate, and mixing with tools/mix_sfx.py (light voice ducking). Not the music bed (that is the final-mix step) and not the visual beats (that is /make-tsx).

Install

Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.

$ npx skills add hassancs91/claude-youtube-editor --skill suggest-sfx

Needs Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.

How to use Suggest Sfx

Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /suggest-sfx.

It contains no scripts, only instructions and reference files, so it can't run code on its own.

What the instructions cover

  1. 1Inputs (read these first, every session)
  2. 2The library (media/library/sfx/) — the durable asset
  3. 3Workflow
  4. 4sfx-plan.json (the source of truth)
  5. 5Tooling quick reference
  6. 6Principles (the house style — apply them)
