Doubao Multimodal Understanding

Bun + TypeScript CLI wrapping the Doubao-Seed multimodal chat completion endpoint. Resolves a single audio/video source (URL or local path), normalizes it for Ark (download remote → cache, upload local → TOS pre-signed URL), splits oversized media, fans out concurrent Ark calls, and merges the results.

Script Directory

{baseDir} = this SKILL.md's directory. Main entry: {baseDir}/scripts/main.ts. Run with bun run {baseDir}/scripts/main.ts .... Dependencies live in {baseDir}/scripts/package.json (run bun install inside that folder once).
