README
Requires DeepSeek Harness ≥ 0.1.5
This plugin line targets DeepSeek Harness 0.1.5+, which ships
uiWorkspacesession navigation andremote.session.create./newrelies on those APIs to switch sessions and reuse the current agent preset.Do not install on harness versions below 0.1.5. The host checks the version and refuses to load this plugin; the browser half will not mount the slash menu either. If your harness is older, upgrade DeepSeek Harness to 0.1.5 or newer first, then install this plugin.
After upgrading harness, restart
dsh web, then run the install command below.
Ultra Slash for DeepSeek Harness: a separate / menu group for this plugin's commands.

Install
Prerequisites:
- DeepSeek Harness 0.1.5 or newer is installed and
dsh webruns. - If
dsh --version(or the host package version) is below 0.1.5, do not install this plugin — upgrade harness first, then install.
Check your harness version:
dsh --version
# or inspect the installed @deepseek-ai/dsh package version
From npm
dsh plugin --profile web add deepseek-harness-ultra-slash@0.2.4
Do not omit @0.2.4: pnpm protects freshly published versions for 24 hours, and a bare install may pick an older release.
From GitHub
dsh plugin --profile web add github:loadingvx/deepseeh-harness-ultra-slash
GitHub install uses the built files in the repo. The default branch must already contain lib/index.js and lib/client.js.
Restart dsh web after installing. If you previously installed the old package name dsh-steer, remove it first:
dsh plugin --profile web remove dsh-steer
