About this skill

Problem

Browser automation often stalls on environment checks: whether 9222 is listening, whether an existing Chrome instance can be reused, or whether a confirmed Chrome executable path is available. Guessing other browsers can introduce inconsistent behavior. This skill keeps the setup path explicit and predictable.

How It Works

Checks whether 9222 is accessible first.
Attaches to an existing Chrome CDP instance when the port is already listening.
Launches a Chrome debugging instance only when a confirmed chromeExecutablePath is provided, then enables 9222.
Operates tabs by listing available tabs, selecting the target page, and running basic page reads, navigation, and scripts.
Reports blockers when the path is unknown, Chrome is missing, or 9222 is unavailable, instead of assuming a local Chrome installation.

Boundaries

The skill is Chrome CDP-specific and does not fall back to Edge or other browsers. It provides a stable runtime entry point for page and tab operations; higher-level automation can add wait logic, retries, and orchestration on top of it.

Use Cases

Check whether port 9222 is listening, attach to the existing Chrome CDP instance, and run page scripts.
Launch a Chrome debugging instance on 9222 using a confirmed executable path, then list and select a tab.
Prepare a Chrome runtime for higher-level skills, connect to a target tab, and perform basic reads, navigation, and scripts.
Report environment failure when 9222 is absent and no Chrome path is provided, without guessing paths or switching browsers.

Best For

Automation engineers who need to check whether a Chrome CDP instance can be attached in CI or local scripts.
Browser tool developers who need to run page inspection scripts against an existing Chrome instance.
Platform developers who need to prepare a Chrome runtime environment for higher-level agent skills.
Test engineers who need to launch Chrome debugging by confirmed path and operate a target tab.
