# 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

```bash
# 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:
```json
{
  "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):

```bash
# 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"
```
