dsh-custom-context-injector

Pasting your role definition, output preferences, or project-specific terminology before every model call is tedious and easy to forget. dsh-custom-context-injector adds a dedicated "Custom Context" page to the DeepSeek Harness settings panel. Toggle the injection switch on, type your context, hit Save, and from then on the text is automatically injected as a systemPrompt section into every model assembly — in the current session and in every new conversation you open afterwards.

Persistence uses a two-tier strategy: an in-memory cache serves synchronous injection at call time, while a local JSON file (.dsh-custom-context.json in the DSH host process working directory) is written on save and reloaded on restart. If disk writing is unavailable the plugin gracefully degrades to an in-memory-only mode and surfaces a notice on the settings page. The injection scope is limited to the realm that loaded the plugin and affects subsequent prompt assembly; it does not retroactively rewrite historical sessions.

This plugin is ideal for users who want a persistent persona, fixed output style, project terminology, or team-level conventions attached to every Harness conversation. Note that it currently ships as a dynamic Cordis Package relying on services injected by the DSH host and is not yet published as a standalone npm package; a formal release is planned once it migrates to a persistent settings namespace or a composition directory.
