Complete solution

Shows how to fix attach AgentQL to an existing browser instead of launching fresh each run. Use it when you hit this exact problem. Skip it when your error message or symptom looks different.

TL;DR

Context: AgentQL GitHub repo README: the examples include scripts for Use Remote Browser and Use Existing Browser alongside list-query usage - the Playwright integration can drive a browser session you already have instead of launching a fresh one every run.

Steps

Do not launch a new browser for every AgentQL script run. The Playwright integration can attach to an existing or remote browser - that keeps your logged-in state and cookies across runs and skips the startup cost. Fresh launches are for isolation; for iterative scraping against the same site, connect to the browser you already have open.

When to use

You are seeing this: Do not launch a new browser for every AgentQL script run. Use this skill when you run into "Attach AgentQL to an existing browser instead of launching fresh each run".

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.
