Studio core

The shared library every studio-* skill imports: OpenRouter providers (text, image, video, speech), usage parsing, the one user-config parser, and the ffmpeg/ffprobe helpers for the video stage.

No npm dependencies. ESM only, Node 24 built-ins (fetch, node:fs, node:path, node:os, node:child_process, node:crypto). No build step, no repo checkout: copy the directory and it runs.

When to use

Use when calling OpenRouter from a studio skill — generating text, images, video clips or speech — or when a skill needs provider cost, the user config file, or the ffmpeg assembly helpers.
