user-Mrz/dsh-system-prompt-studio

Per-conversation system prompt studio for DeepSeek Harness. Append text, shadow-replace one named first-party prompt section, or replace the whole system prompt; changes apply on the next model request without a restart. Overrides persist per session and are inherited by forked conversations along the parent chain, with a Pin action to freeze the inherited result locally. The panel lists the real assembled sections and guards unsaved edits.
