dsh-plugin-reasonix

Website · Documentation · Source

Use Reasonix as a subagent in DeepSeek Harness (dsh). The package is configuration only: one patch layer that points Harness's subagent-acp provider at reasonix acp and exposes it to the model as a reasonix tool. It contains no code.

Before you install

1. Install Reasonix and run reasonix setup once on the same machine. Reasonix reads its provider key from its own home, not from environment variables, so Harness cannot pass one.
2. Make sure reasonix is on the PATH of the process that runs dsh.

Install

dsh plugin --profile  add github:esengine/DeepSeek-Reasonix#path:/integrations/dsh-plugin

The package is not on npm; pnpm installs the integrations/dsh-plugin subdirectory of this repository (the path: selector, see pnpm package sources).

After installing: switch it on

An installed plugin starts off. Open its page in the DSH Web UI and turn the switch on.

• The switch and both components must read Running. Turning it on in a running dsh web is enough: the next new session has the reasonix tool (observed on dsh 0.2.1-rc.2). Restart dsh only if it is still missing.
• While it is off the model may run reasonix -p in its own shell.
• That looks like a delegation and is not one: there is no subagent, and the permission policy below does not apply.

What it changes

Permissions

• permission: reject is the default. Every approval card Reasonix raises is declined, so the child can read and research but cannot write files or run commands that need approval.
• permission: allow makes Harness accept every card automatically. The delegated task can then do anything Reasonix's tools can do in that workspace.
• Change the policy only in your own cordis.patch.yml, for a task and workspace you would approve wholesale.

Versions

The provider version must equal your dsh version. This release pins dsh 0.2.1-rc.2.
