X Post

Automated, anti-bot-resilient publishing toolchain for X (Twitter) leveraging real Chrome instances controlled via Chrome DevTools Protocol (CDP).

Runtime Requirements (Pre-flight)

Before executing any script, verify environment dependencies → references/runtime-setup.md.

Essential Checklist:

• Bun runtime installed (bun --version)
• Google Chrome or Chromium installed (or X_BROWSER_CHROME_PATH set)
• First-time run: authenticate into X in the opened Chrome window (session saved to ~/.local/share/x-browser-profile)
• For video translation: yt-dlp, ffmpeg, and whisper-cli installed

If any required tool is missing, stop and inform the user immediately.

Capabilities & Navigation Map

Choose the workflow appropriate for the publishing task:

1. Regular Posts (Text, Images & Threads)

Publish standard tweets with up to 4 images and thread replies.

# Preview mode (verifies compose box and keeps window open for 30s)
bun scripts/x-browser.ts "Exploring agentic automation with Antigravity!" --image ./screenshot.png

# Publish with images and thread reply
bun scripts/x-browser.ts "Announcing our new open-source release!" \
  --image ./banner.png \
  --reply "Check out the repo here: https://github.com/org/repo" \
  --submit

• Details, image specs, and multi-thread chaining → references/regular-posts.md

2. Video Posts

Publish videos (MP4, MOV, WebM) with automatic upload and transcode polling.

# Preview video upload
bun scripts/x-video.ts --video ./demo.mp4 "Watch the complete architecture walkthrough"

# Publish video with source citation in reply thread
bun scripts/x-video.ts --video ./demo.mp4 \
  "Autonomous coding loop benchmark" \
  --reply "Benchmarked on SWE-bench verified dataset." \
  --submit

• Duration limits, formats, and upload states → references/video-posts.md

3. Quote Tweets

Quote an existing public tweet with custom commentary while preserving source attribution.

# Preview quote tweet
bun scripts/x-quote.ts https://x.com/username/status/1234567890 "Important perspective on LLM agents!"

# Publish quote tweet directly
bun scripts/x-quote.ts https://x.com/username/status/1234567890 "Strongly agree with this analysis." --submit

• URL normalization and menu selectors → references/quote-tweets.md

4. Long-Form X Articles (Markdown)

Convert Markdown documents with headings, lists, blockquotes, cover images, and inline images into X Articles (requires X Premium).

# Preview formatted article draft
bun scripts/x-article.ts ./article.md --cover ./cover.png

# Publish article directly
bun scripts/x-article.ts ./article.md --submit

• Frontmatter syntax and image placeholder mechanics → references/articles.md

5. Video Translation & Subtitle Workflow

Download foreign-language video tweets, transcribe audio via Whisper, generate editable translation files, burn styled subtitles, and publish with source attribution.

# Step 1: Ingest URL and create translation draft (/tmp/x-translate/<id>/translation.md)
bun scripts/x-translate-video.ts https://x.com/username/status/1234567890 --target-lang English

# Step 2: Edit /tmp/x-translate/<id>/translation.md with translated copy & SRT

# Step 3: Burn subtitles and preview
bun scripts/x-translate-video.ts --confirm /tmp/x-translate/<id>/translation.md

# Step 4: Burn subtitles and publish
bun scripts/x-translate-video.ts --confirm /tmp/x-translate/<id>/translation.md --submit

• Full pipeline and FFmpeg subtitle styling → references/video-translation.md

Execution Principles & Safety

1. Always Preview First: Run commands without --submit during development or manual review.
2. Persistent Profile: All scripts share ~/.local/share/x-browser-profile so authentication is required only once.
3. Native Keystroke Dispatch: Media assets use hardware-level paste simulation (copy-to-clipboard.ts + paste-from-clipboard.ts) to avoid CDP synthetic event blocks.
4. Issue Resolution: For login timeouts, clipboard permissions, or CDP connection errors → references/troubleshooting.md.
