The substring "not found" is too generic and could match unintended error messages. For example, it would match errors like "modal: command not found", "file not found", or "module not found", which would incorrectly trigger environment creation instead of failing with the actual error.

Based on the PR description, the new error format is "Environment 'pytest' not found". Consider using a more specific check like "Environment" in result.stderr and "not found" in result.stderr, or use a case-insensitive pattern match for "environment.*not found".

Suggested change
if "No such environment" in result.stderr or "not found" in result.stderr:
if "No such environment" in result.stderr or (
"Environment" in result.stderr and "not found" in result.stderr
):
