Bind the browser, print attach instructions, and pause on the first plugin context so agents can attach via `python -m playwright cli`. Requires -s/--capture=no and a single xdist worker. Mirrors the skill- based path from microsoft/playwright#38610 (not MCP). Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: 36905b3d-2f7c-4da8-8cc7-a644814e8004
Same as microsoft/playwright-python#3091. PyPI publishing is unaffected (handled by .azure-pipelines/publish.yml). conda-forge still has the package if people want it from there.

--playwright-debug=cli, so a pytest run can pause and print apython -m playwright cli attach …command that agents (or you) can use to inspect the live browser.pytest --playwright-debug=cli -s # → attach with: python -m playwright cli attach tw-…On the first plugin
new_context, webrowser.bind(), print the attach banner, zero timeouts, andrequest_pause(). Later contexts are left alone - CLI attach only drivescontexts()[0]. No unbind on teardown (same rough shape as JS today).Guards:
-s/--capture=no(so the attach line isn't swallowed)-n≠ 1playwright>=1.59(browser.bind+ context debugger)Covered with configure-guard tests plus a real attach → snapshot → resume e2e for both sync and asyncio.
This is the skill-based path from microsoft/playwright#38610, not MCP. Pytest codegen / skills docs can follow separately.
