Baoyu Danger X To Markdown Agent Skill

X to Markdown

Converts X content to markdown:

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

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

• Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
• Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
• Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

Script Directory

Scripts located in scripts/ subdirectory.

Path Resolution:

• {baseDir} = this SKILL.md's directory
• Script path = {baseDir}/scripts/main.ts
• Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun

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)

Check EXTEND.md in priority order — the first one found wins:

| Priority | Path | Scope |

|----------|------|-------|

| 1 | .baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md | Project |

| 2 | ${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md | XDG |

| 3 | $HOME/.baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md | User home |

| Result | Action |

|--------|--------|

| Found | Read, parse, apply settings |

| Not found | MUST run first-time setup (see below) — do NOT silently create defaults |

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}/{content-slug}.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:

| Setting | Behavior |

|---------|----------|

| 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

• Run script without --download-media → markdown saved
• Check saved markdown for remote media URLs (https:// in image/video links)
• If no remote media found → done, no prompt needed
• 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
• If user confirms → run script again with --download-media (overwrites markdown with localized links)

Authentication

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

Extension Support

Custom configurations via EXTEND.md. See Preferences section for paths and supported options.
