x-cdp（X CDP 搜索）

X CDP Skill — Browser Automation for X (Twitter)

First-Time Setup

Run the setup wizard. It checks everything and auto-fixes what it can:

node scripts/setup.js [--port 18802] [--profile ~/chromium-profiles/x-cdp]

The wizard does 4 things:

1. Finds Chromium/Chrome on your system (or tells you how to install it)
2. Checks puppeteer-core (auto-installs to /tmp/node_modules if missing)
3. Launches Chromium with CDP enabled on the specified port
4. Verifies X login (tells you to log in manually if needed)

Manual setup (if you prefer)

Install Chromium (recommended over Chrome for version stability):

# macOS
brew install --cask chromium

# Linux
sudo apt install chromium-browser

Install puppeteer-core:

cd /tmp && npm init -y && npm install puppeteer-core

Launch Chromium with CDP:

chromium --remote-debugging-port=18802 --user-data-dir=~/chromium-profiles/x-cdp --no-first-run

Log in to X: Open x.com in the Chromium window and log in once. The session persists in the profile directory.

Why Chromium, not Chrome?

Chrome auto-updates silently. One update can change DOM selectors and break all automation overnight. Chromium lets you pin a known-good version. That said, Chrome works fine too if you don't mind occasional breakage.

Architecture

All scripts connect to a running Chromium instance via CDP (Chrome DevTools Protocol). This is not API-based. It drives the real browser UI, identical to a human clicking.

Multi-account isolation

Each X account gets its own Chromium instance with a separate port and profile:

• Port 18800, profile chromium-profiles/main: @your_main_account
• Port 18801, profile chromium-profiles/second: @your_second_account
• Port 18802, profile chromium-profiles/third: @your_third_account

Launch multiple instances for multi-account use. All scripts accept --port to target a specific account.

Commands

Post a tweet

NODE_PATH=/tmp/node_modules node scripts/post-tweet.js "Hello world" [--image /path/to/img.png] [--port 18802] [--dry-run]

Reply to a tweet

NODE_PATH=/tmp/node_modules node scripts/reply-tweet.js <tweet_url> "Nice post!" [--image /path/to/img.png] [--port 18802] [--dry-run]

Quote retweet

NODE_PATH=/tmp/node_modules node scripts/quote-tweet.js <tweet_url> "My thoughts" [--port 18802] [--dry-run]

Publish an article (X Premium)

NODE_PATH=/tmp/node_modules node scripts/post-article.js --title "Title" --body "Body text" [--body-file /path/to/content.md] [--cover /path/to/cover.jpg] [--port 18800] [--dry-run]

All scripts support --dry-run to fill content without sending. A screenshot is saved to /tmp/.

Agent Integration

When the user asks to interact with X:

Pre-flight check

Before running any script, verify the environment:

1. Check if Chromium is running on the target port: curl -s http://localhost:<port>/json/version
2. If not running, run node scripts/setup.js --port <port> to launch and configure
3. If setup fails, report the specific step that failed

Compose flow

1. User provides intent (e.g., "reply to this tweet saying thanks")
2. Agent drafts the text, shows it to user for approval
3. On confirmation, run the script via exec
4. Report success/failure

Error recovery

If a script fails with "not found" errors, X may have changed its DOM. Check and update:

• references/selectors.md for the latest selectors
• scripts/lib/cdp-utils.js SELECTORS object

Risk Notes

• Rate limiting: Space out actions. No more than ~10 tweets/hour.
• Detection: CDP automation looks like real browser usage. Much harder to detect than API abuse.
• Account safety: Human-like delays are built into all scripts. Avoid bulk operations.
• vs API tools (bird etc.): API wrappers get DMCA'd or break on API changes. CDP works as long as the website works.
