What is media-generation?

A command-line toolkit for creating and editing images and videos, generating speech, and working with audio. It supports audio transcription and translation through multiple AI providers.

Use it to generate or edit images, create or extend videos, animate images, synthesize or clone voices, remove background sound, transcribe audio, and translate speech.

It puts several media-creation and audio-processing tasks behind one command-line interface, so developers do not need a separate workflow for each type of output.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/onimusya/media-gen

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.

Model	Per session	Once invoked
Fable 5.1	$0.00088	$0.02356
Opus 5.5	$0.00035	$0.00942
Sonnet 5.5	$0.00018	$0.00471
Haiku 4.5	$0.00009	$0.00236

Security

Grade A, and why

media-generation scanned grade A with 0 findings 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 15d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/install.cmd, scripts/install.ps1, scripts/install.sh, …), 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Media Generation

Run the CLI at ${CLAUDE_SKILL_DIR}/scripts/media-gen.mjs with Node.js. Always use --json for parseable output.

node ${CLAUDE_SKILL_DIR}/scripts/media-gen.mjs <command> [options] --json

What ships with it

9 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.
