Fix extension-less filenames never getting a .txt default

[Osamaali313]

Problem

ResourceHelper.make_written_file_resource (superagi/helper/resource_helper.py) tries to give a .txt extension to a written file that has none:

file_parts = os.path.splitext(file_name)
if len(file_parts) <= 1:
    file_name = file_name + ".txt"
file_extension = os.path.splitext(file_name)[1][1:]

os.path.splitext() always returns a 2-tuple (root, ext), so len(file_parts) is always 2 and len(file_parts) <= 1 is never true. The .txt default is dead code.

The intent is clearly "if the filename has no extension, append .txt" — and the very next line reads the extension from os.path.splitext(file_name)[1], confirming the extension lives in the tuple's [1] slot, not in its length.

Impact

An agent writing an extension-less file (e.g. report) is stored with no .txt suffix, and its file_type classification falls through to application/misc instead of application/txt. make_written_file_resource is the write path used by resource_manager/file_manager.py (write_to_s3 via write_file/write_binary_file/write_csv_file).

Reproduction

file_name = "report"   # no extension

	file_name	file_type
before (len(file_parts) <= 1)	report	application/misc ❌
after (not file_parts[1])	report.txt	application/txt ✅

Fix

if not file_parts[1]:
    file_name = file_name + ".txt"
