## Preferences (EXTEND.md)

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

```bash
# Check project-level first
test -f .canghe-skills/canghe-post-to-x/EXTEND.md && echo "project"

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

**EXTEND.md Supports**: Default Chrome profile

## Prerequisites

- Google Chrome or Chromium
- `bun` runtime
- First run: log in to X manually (session saved)

## Pre-flight Check (Optional)

Before first use, suggest running the environment check. User can skip if they prefer.

```bash
npx -y bun ${SKILL_DIR}/scripts/check-paste-permissions.ts
```

Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, Chrome conflicts.

**If any check fails**, provide fix guidance per item:

| Check | Fix |
|-------|-----|
| Chrome | Install Chrome or set `X_BROWSER_CHROME_PATH` env var |
| Profile dir | Ensure `~/.local/share/x-browser-profile` is writable |
| Bun runtime | `curl -fsSL https://bun.sh/install \| bash` |
| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
| Clipboard copy | Ensure Swift/AppKit available (macOS Xcode CLI tools: `xcode-select --install`) |
| Paste keystroke (macOS) | Same as Accessibility fix above |
| Paste keystroke (Linux) | Install `xdotool` (X11) or `ydotool` (Wayland) |

## Troubleshooting

### Chrome debug port not ready

If a script fails with `Chrome debug port not ready` or `Unable to connect`, kill existing Chrome CDP instances first, then retry:

```bash
pkill -f "Chrome.*remote-debugging-port" 2>/dev/null; pkill -f "Chromium.*remote-debugging-port" 2>/dev/null; sleep 2
```

**Important**: This should be done automatically — when encountering this error, kill Chrome CDP instances and retry the command without asking the user.

## Notes

- First run: manual login required (session persists)
- All scripts only fill content into the browser, user must review and publish manually
- Cross-platform: macOS, Linux, Windows

## Extension Support

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