What is the Browser CDP SkillProof Score?

7.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 4/5.

How do I install Browser CDP?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Browser CDP with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 17, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 5667f33

The bundled setup-cdp-chrome.js ran cleanly in --detect-only and --dry-run, correctly detecting the user's live Chrome and refusing to kill it without --yes (exits code 3 NEEDS_CONSENT in non-TTY, which is the right safety default). It copies the Chrome profile locally to reuse login state and stays on-machine with no network exfiltration. The task delta is unmeasured: the real path needs a global agent-browser install (not present) and would kill the user's running Chrome, so the automation itself could not be safely exercised. The skill body is almost entirely in Chinese.

What Browser CDP does

A runbook plus setup script for controlling Chrome through the DevTools Protocol so automation reuses your already-logged-in session: launch Chrome in debug mode, open URLs, run JavaScript, take snapshots, and extract auth tokens via the agent-browser CLI. Triggers on browser automation, CDP, agent-browser, or extract token from browser. Requires a global agent-browser install and will restart your Chrome.

How to install Browser CDP

git clone https://github.com/worldwonderer/oh-story-claudecode
mkdir -p ~/.claude/skills
cd oh-story-claudecode && cp -r skills/browser-cdp ~/.claude/skills/browser-cdp

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Browser CDP

/browser-cdp Drive Chrome over CDP to reuse existing login sessions for automation

It also activates on plain-language prompts like these:

automate my browser but keep me logged into my accounts
extract my auth token from my already-logged-in Chrome session
control Chrome over CDP without making me log in again
