DeepSeek Harness Plugin: dsh-prompt-injector (General Per-Turn Context Injection)

`dsh-prompt-injector` is a plugin for DeepSeek Harness (DSH) designed to address the issue of rules being forgotten in long sessions. It leverages the memory mechanism, allows prompt lists to be managed via a UI, and injects context in the form of a “Context injection” notification line for each conversation (or after context compaction), ensuring that the model always “sees” critical rules. The plugin’s core features include per-turn injection, selectable trigger modes, abbreviation filtering, a zero-intrusion design, and UI-based management. It is responsible only for injecting text into the context and does not execute any actions, making it suitable for repeatedly emphasizing specific constraints in coding or complex Q&A scenarios.
