DeepSeek Harness memory: profile state, made durable
DeepSeek Harness runs long sessions under a profile, and profile state is local. Long runs are exactly where losing the middle of the story gets expensive.

How DeepSeek Harness handles memory today
Harness state is organized by profile on the machine running it, so a long agent run accumulates context inside that profile and nowhere else.
Plugins are the supported extension point, and dsh-memoryrouter adds a MemoryRouter-backed memory layer with a documented config block.
What DeepSeek Harness forgets
A long run that keeps everything in one profile loses everything with that profile.
- Context when you switch machines or rebuild the environment.
- The early parts of long runs once the working context is trimmed.
- Cross-runtime continuity with your other agents.
- Any audit trail of why a decision was made two days into a run.
The fix with MemoryRouter
Install the plugin into your profile, add the config block, and the harness gains memory that outlives the run and the machine.
