# NousResearch/hermes-agent · NUL character handling in terminal script reads

## Open now

- Nothing open on GitHub.

These items address a bug where null (NUL) characters in script reads—originating in _read_script_in_env—could corrupt paths or allow dot-sourced and NUL-padded scripts to bypass lifecycle guards. The work involves normalizing or stripping NUL bytes during script ingestion.
