AutoSkill baoyu-danger-x-to-markdown

source content

X to Markdown

Converts X content to markdown:

  • Tweets/threads → Markdown with YAML front matter
  • X Articles → Full content extraction

Script Directory

Scripts located in 

scripts/
subdirectory.

Path Resolution:

  1. SKILL_DIR
    = this SKILL.md's directory
  2. Script path = 
    ${SKILL_DIR}/scripts/main.ts

Consent Requirement

Before any conversion, check and obtain consent.

Consent Flow

Step 1: Check consent file

# macOS
cat ~/Library/Application\ Support/baoyu-skills/x-to-markdown/consent.json

# Linux
cat ~/.local/share/baoyu-skills/x-to-markdown/consent.json

Step 2: If 

accepted: true
and 
disclaimerVersion: "1.0"
→ print warning and proceed:

Warning: Using reverse-engineered X API. Accepted on: <acceptedAt>

Step 3: If missing or version mismatch → display disclaimer:

DISCLAIMER

This tool uses a reverse-engineered X API, NOT official.

Risks:
- May break if X changes API
- No guarantees or support
- Possible account restrictions
- Use at your own risk

Accept terms and continue?

Use 

AskUserQuestion
with options: "Yes, I accept" | "No, I decline"

Step 4: On accept → create consent file:

{
  "version": 1,
  "accepted": true,
  "acceptedAt": "<ISO timestamp>",
  "disclaimerVersion": "1.0"
}

Step 5: On decline → output "User declined. Exiting." and stop.

Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# Check project-level first
test -f .baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md" && echo "user"

EXTEND.md Supports: Download media by default | Default output directory

First-Time Setup (BLOCKING)

CRITICAL: When EXTEND.md is not found, you MUST use 

AskUserQuestion
to ask the user for their preferences before creating EXTEND.md. NEVER create EXTEND.md with defaults without asking. This is a BLOCKING operation — do NOT proceed with any conversion until setup is complete.

Use 

AskUserQuestion
with ALL questions in ONE call:

Question 1 — header: "Media", question: "How to handle images and videos in tweets?"

  • "Ask each time (Recommended)" — After saving markdown, ask whether to download media
  • "Always download" — Always download media to local imgs/ and videos/ directories
  • "Never download" — Keep original remote URLs in markdown

Question 2 — header: "Output", question: "Default output directory?"

  • "x-to-markdown (Recommended)" — Save to ./x-to-markdown/{username}/{tweet-id}.md
  • (User may choose "Other" to type a custom path)

Question 3 — header: "Save", question: "Where to save preferences?"

  • "User (Recommended)" — ~/.baoyu-skills/ (all projects)
  • "Project" — .baoyu-skills/ (this project only)

After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.

Content...

File structure: 

x-to-markdown/{username}/{tweet-id}.md

When 

--download-media
is enabled:

  • Images are saved to 
    imgs/
    next to the markdown file
  • Videos are saved to 
    videos/
    next to the markdown file
  • Markdown media links are rewritten to local relative paths

Media Download Workflow

Based on 

download_media
setting in EXTEND.md:

SettingBehavior
1
(always)		Run script with 
--download-media
flag
0
(never)		Run script without 
--download-media
flag
ask
(default)		Follow the ask-each-time flow below

Ask-Each-Time Flow

  1. Run script without 
    --download-media
    → markdown saved
  2. Check saved markdown for remote media URLs (
    https://
    in image/video links)
  3. If no remote media found → done, no prompt needed
  4. If remote media found → use 
    AskUserQuestion
    :
    • header: "Media", question: "Download N images/videos to local files?"
    • "Yes" — Download to local directories
    • "No" — Keep remote URLs
  5. If user confirms → run script again with 
    --download-media
    (overwrites markdown with localized links)

Authentication

  1. Environment variables (preferred): 
    X_AUTH_TOKEN
    , 
    X_CT0
  2. Chrome login (fallback): Auto-opens Chrome, caches cookies locally
