cdp-browser

CLI for Chrome/Chromium at localhost:9222. Inspect tabs, take screenshots, navigate, scroll, post to X, or run JS in a persistent browser session.

Repo: https://github.com/gostlightai/cdp-browser

Prerequisites: Chromium running with --remote-debugging-port=9222. Docker Compose or a local Chrome with remote debugging enabled.

Commands

Run from the skill dir (bin/ scripts):

Command	Description
status	List all tabs (JSON from CDP)
tabs	Same as status
new	Open new tab
goto	Navigate tab to URL
snapshot	Full-page screenshot (PNG)
close-popup	Dismiss dialogs/modals
`scroll`	sel> [down\	up]	Scroll by pixels or selector
query getUrl	Return current page URL
query getText [selector]	Return element text (or body)
query getHtml [selector]	Return element HTML (or body)
tweet-draft "text"	Fill compose box only; does NOT post
tweet-post --confirm "text"	Post tweet (requires --confirm as second arg)
tweet "text"	Alias for tweet-draft (fills compose only)

Tweet flow

tweet-draft (default): Fills the compose box; user reviews in browser and posts manually.
tweet-post: Requires --confirm as second arg (strict). Use when user explicitly approves ("go ahead", "post it", or Telegram confirm button).
Optional Telegram confirm: When tweet.confirmButton is enabled in config, the agent can run tweet-draft --save-pending to write pending state, then send a message with an inline "Confirm Post" button. On confirm, the agent runs tweet-post --confirm.

Config (required for Telegram confirm button)

The Telegram "Confirm Post" button only works if config exists. Copy the example and place it in your workspace:

bash

# From the skill dir (e.g. ~/.openclaw/workspace/skills/cdp-browser):
cp .cdp-browser.json.example ~/.openclaw/workspace/.cdp-browser.json

Location: ~/.openclaw/workspace/.cdp-browser.json (or $OPENCLAW_WORKSPACE/.cdp-browser.json)

Key	Default	Description
tweet.confirmButton	false	When true, agent sends draft with inline "Confirm Post" button in Telegram. User clicks to approve or says "go ahead".

Without this config, the agent uses plain tweet-draft (no button); user confirms via text only.

Telegram confirm button (agent instructions)

When tweet.confirmButton is true (config present) and you are in a Telegram session:

Draft: Run tweet-draft --save-pending "text" from the skill dir. This fills the compose box and writes ~/.openclaw/workspace/.cdp-browser/pending-tweet.json.
Send with button: Run from the skill dir:

bash

./scripts/send-tweet-confirm.sh <chat_id> "<tweet_text>"

Or use openclaw message send directly with --buttons '[[{"text":"Confirm Post","callback_data":"cdp:tweet:confirm"}]]'. Use the current session's reply target as .

On confirm: When the user clicks the button, OpenClaw delivers callback_data: cdp:tweet:confirm. Or the user says "go ahead"/"post it". Treat either as approval. Then:
Read ~/.openclaw/workspace/.cdp-browser/pending-tweet.json for text and tabId
Run tweet-post --confirm ""
Edit or delete the message with the button (optional)
Delete the pending file

Scripts

cdp.js — Fetch-only wrapper for CDP HTTP API (/json, /json/list, /json/new); no shell.
pw.js — Playwright connect to browser; runs snapshot/goto/scroll/query/tweet-draft/tweet-post. Compose launcher: SideNav_NewTweet_Button, /compose/post, Post only (avoids reply buttons). Post button: tweetButton, tweetButtonInline.

Security

See SECURITY.md for mitigations and operational notes.
