In April 2026, Una Yung enhanced the Hermes agent in the NousResearch/hermes-agent repository by addressing output hygiene issues related to internal thinking blocks. She implemented a Python-based solution using regular expressions and text processing to reliably strip <thought> tags from both Gemma 4 responses and streaming CLI output. By consolidating the tag-stripping logic into a single function, she ensured consistent behavior across different response rendering and streaming paths. This targeted bug fix improved the user experience by preventing unintended internal content from surfacing, demonstrating careful attention to detail and a methodical approach to CLI development and bug resolution.
