DeepSeek Harness

The plugin gives DeepSeek Harness the Inbox tool and plan review. Your reply arrives once it is idle.

Native plug-in · Inbox built in and your reply wakes it

From the Plugins page

Add @plannotator/dsh from the Plugins page in DeepSeek Harness Web or Desktop.

Turn the tool on without the Inbox

Merge this into your Plannotator config. Then restart DeepSeek Harness.

~/.plannotator/config.json

{ "inboxTool": { "dsh": true } }

Check it works

Paste this into DeepSeek Harness.

You should see A question arrives in the Inbox. Answer it and press Send. The thread reads Delivered to DeepSeek Harness and DeepSeek Harness goes on with your answer.

Troubleshooting

The agent has no plannotator_inbox tool: Run plannotator inbox once: it turns the tool on when it finds the plugin. If you turned the tool off yourself, turn it on in Settings → Agents. Then restart DeepSeek Harness.
No tool in a headless or sdk or acp profile: Those profiles get no tool and no wake. Use an interactive profile.
You connected it as an MCP server: Use the plugin instead. Over MCP the Inbox can’t tell DeepSeek Harness sessions apart and can’t wake them.
The Inbox doesn’t open: Read ~/.plannotator/inbox/inbox.log. Stop a stuck Inbox process and run plannotator inbox again.
