 ### Fixed
 
+- Fixed the compaction summarization system prompt to use neutral AI assistant wording for non-coding agents ([#5401](https://github.com/earendil-works/pi/issues/5401)).
 - Fixed `models.json` schema support for OpenAI Responses `compat.supportsDeveloperRole` ([#5456](https://github.com/earendil-works/pi/issues/5456)).
 - Fixed tmux setup documentation to require tmux 3.5 for `extended-keys-format csi-u` and document the tmux 3.2-3.4 fallback ([#5432](https://github.com/earendil-works/pi/issues/5432)).
 - Fixed built-in tool expand hints to style closing parentheses consistently ([#5359](https://github.com/earendil-works/pi/issues/5359)).
