name: douyin-upload-skill description: Login and publish Douyin (China mainland) videos from local files with OAuth, local speech-to-text, and generated caption drafts. Use when users ask to authorize Douyin accounts, upload local videos, auto-generate title/description from video audio, confirm content, and publish via official Douyin OpenAPI with fallback export when publish permissions are missing.

Douyin Upload Skill

Overview

Use this skill to publish local videos to Douyin with a deterministic CLI flow:

1. Validate local dependencies and env.
2. OAuth authorize and store encrypted token locally.
3. Prepare video metadata and transcript from local audio.
4. Generate 3 caption candidates in chat from transcript.
5. Confirm or edit caption, then publish.
6. If official publish permission is unavailable, export an outbox package for manual publish.

Use the script at <skill_root>/scripts/douyin.js.

Required Environment

Set these environment variables before auth or publish:

• DOUYIN_CLIENT_KEY
• DOUYIN_CLIENT_SECRET
• DOUYIN_REDIRECT_URI

Optional overrides:

• DOUYIN_SCOPE
• DOUYIN_TOKEN_ENC_KEY
• DOUYIN_ASR_MODE (api / whisper-gpu / whisper-cpu)
• DOUYIN_ASR_API_URL
• DOUYIN_ASR_API_MODEL
• DOUYIN_ASR_API_KEY
• DOUYIN_WHISPER_BIN
• DOUYIN_WHISPER_MODEL_PATH
• DOUYIN_FFMPEG_BIN
• DOUYIN_FFPROBE_BIN

Workflow

1. Run dependency checks:

node <skill_root>/scripts/douyin.js doctor

1. Authorize account (manual code paste flow):

node <skill_root>/scripts/douyin.js auth

1. Prepare transcript and metadata from a local video path. Accept both Linux and Windows path formats.

node <skill_root>/scripts/douyin.js prepare --video "E:\\videos\\demo.mp4"

1. Create 3 caption candidates from transcript.text with this structure:

• Line 1: title hook
• Line 2-3: concise description
• Final line: 2-5 hashtags

1. Ask user to select or edit one final caption.

2. Publish with explicit visibility and confirmation policy:

node <skill_root>/scripts/douyin.js publish \
  --video "E:\\videos\\demo.mp4" \
  --text "<final caption>" \
  --private-status 0 \
  --auto-confirm false

Command Behavior

• doctor: reports dependency and env readiness plus install hints.
• auth: opens OAuth URL, accepts pasted callback URL or code, stores encrypted token.
• prepare: returns metadata, transcript, and ASR failure detail (without stopping publish flow).
• publish: uploads and creates video via official API. If permission-like API errors occur, writes fallback files under outbox and returns mode: fallback.
• config: stores persistent settings (defaultPrivateStatus, autoConfirm, whisperBin, whisperModelPath, outboxDir, etc.).

Caption Rules

Before publish:

• Keep final text length <= 1000.
• Always show the final draft to the user.
• If auto-confirm is false, require explicit user confirmation in terminal.

Output Contracts

Treat script stdout as JSON. Always parse and branch by:

• ok
• command
• mode (official or fallback for publish)
• asrError (optional in prepare)
