• Consider using logger.warning instead of logger.info here (and similarly in subsequent exception handling blocks) to better reflect the severity of file access errors.

logger.info("Warning: Could not access/process file %s: %s", filepath_rel_posix, e)

The current token estimate is based on splitting the output text by whitespace. Consider documenting that this is an approximation of token count for LLM context purposes.

Suggested change

	# Approximate token count based on splitting the text by whitespace.
	# Note: This does not reflect the actual tokenization process used by LLMs,
	# which may result in a different token count due to subword tokenization and special characters.
