audio-explainer

audio-explainer is a skill for Claude Code, Codex from alecs5am/ralphy. It costs 353 tokens per session (3,727 once invoked), scanned A, original, Apache-2.0.

A workflow for turning one audio file, or a YouTube or podcast URL, into a 5–30 minute video with text, images, and other overlays instead of a person on camera.

In plain words
What is it for?
Use it for developer essays, technology explainers, and tech-podcast-style videos in a 16:9 format. It does not cover short clips, music videos, or multi-speaker interviews.
Why use it?
It provides a route for making a long-form explainer from spoken audio when the result should not show a talking head.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

audio-explainer scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/capture-screenshot.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Trigger refinements

ALSO FIRE when the user drops a YouTube / podcast URL whose duration is > 4 minutes AND asks for "a video" (not "a clip" / "a short" / "a cut") — that is the audio-to-longform path, not the short-form cut path. Long-form on a URL: pull --audio-only, then run this skill on the audio.

DO NOT FIRE for:

  • Short-form cuts (< 4 min) from a long-form source — route to podcast-clip template.
  • Talking-head essays where the user wants their face on screen — route to yap-talking-head or green-screen-explainer.
  • Multi-speaker debates / interviews — route to interview-dialog (split-screen) or podcast-clip (cut viral moments).
  • Music videos / non-speech audio — route to music-video template.
  • Once the project has index.html composed and the user wants render / preview tweaks — handback to the editor playbook.

Hard invariants

  1. ralphy is the only entry-point. No direct ffmpeg, yt-dlp, curl, or bunx tsx against provider SDKs. Every step in the workflow below is either a ralphy verb (already shipped) or an LLM call routed through cli/lib/providers/llm.ts → callLLM(). AGENTS invariant #2.
  2. Append-only on the project dir. Per AGENTS invariant #14, every regeneration writes .v2 / .v3 files. Never overwrite overlay-plan.json, captions.json, or any asset in artifacts/. The skill writes a new version; the user picks which to promote.
  3. English-only on disk. Every file the skill writes lands in English. If the source audio is Russian / Spanish / etc., the on-disk overlay-plan.json keeps vo_text in the source language (it's transcript content) but every comment, log line, file name, and skill-generated annotation is English. Chat with the user matches their language.
  4. No raw API code. Browser screenshots run through a Playwright helper script the skill calls via bunx playwright, not via raw puppeteer.launch() in inline code. Image generation goes through ralphy generate image. Music + SFX through ralphy generate music + ralphy generate sfx. No direct ElevenLabs HTTP calls.
  5. Composition must be deterministic. The HyperFrames index.html the skill emits has no Date.now() / unseeded Math.random() / fetch() at render time. Per .agents/skills/hyperframes/references/playbook.md hard invariants.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
