Summary

• 14 commands covering the full Douyin creator workflow: publish, draft, videos, drafts, delete, profile, update, hashtag (search/suggest/hot), location, activities, collections, stats
• 8-phase publish pipeline: STS2 credentials → ApplyVideoUpload → TOS multipart upload (Node.js, resume support) → ImageX cover upload → enable video → transcode poll (encode=2) → content safety check → create_v2
• Browser-fetch hybrid architecture: all creator.douyin.com signed API calls run via page.evaluate(fetch) (handles a_bogus signing automatically); large binary uploads go Node.js-direct with AWS Signature V4

Key technical notes

• Only scheduled publishing supported (timing must be now+2h ~ now+14d)
• TOS multipart upload with resume: progress stored at ~/.opencli/douyin-resume/<sha256>.json
• Cover is required: if not supplied, uses poster_uri from transcode response
• encode=2 signals transcode complete (not 1)
• Double-serialized fields in create_v2 body (text_extra, activity, etc.) are JSON.stringify'd strings as required by the API
