omdsh-dev/dsh-mnemon

This is a native DSH plugin built exclusively for DeepSeek Harness that adds composable, cross-session agent memory capabilities to the platform. It ships with a default three-tier memory architecture that splits content into runtime data, searchable documents, and durable long-term memory spaces, and adds a unified visual interface to DSH’s sidebar. It follows DSH’s plugin packaging standard and includes a valid bundle manifest for DSH to load correctly, can be installed directly via DSH’s built-in plugin management command, and supports extending core functionality with custom sources and strategies.

It is designed for DSH users who need to persistently manage project context, knowledge, and decision records across multiple sessions. The typical workflow has users sort different types of information into the matching memory tier, and the plugin automatically pulls relevant memory to the agent for each new conversation turn. It also supports automatic idle memory review with configurable intervals and attempt limits to keep memory organized, and users can activate or deactivate individual memory spaces on demand, as well as perform full CRUD operations on any memory entry.

This plugin is released under the open-source MIT license, meaning it is free to use, modify, and distribute for any purpose. It defaults to a local-first architecture that keeps all user memory on the local machine, but users who want to use the native backend need to install the separate mnemon CLI tool before running the plugin. Third-party backend services are disabled by default and require explicit manual configuration, and third-party extensions run in-process without sandboxing, so users should vet third-party extensions before installing them to avoid security issues.
