01What can it help you accomplish?
Ask a quick side question without interrupting the main DeepSeek Harness conversation
A one-shot `/btw` answer that runs in the background while the main conversation stays usable
DSH users who do not want to pollute the main thread just to check one fact
Open a persistent side thread that inherits the finished context of the main session
A `/side` fork in DSH's native sidebar that keeps its own messages and tool activity, plus `/side list` to enumerate the direct child sessions
People who need follow-up questions on the same topic without derailing the main session
Restrict which tools a side conversation may call
A tool allowlist configured through the plugin's `readOnlyTools` config; calls outside the list are intercepted and the main session is unaffected
Teams that want read-only side chats over a live repository
02How to install into DeepSeek Harness
Prerequisites
- DSH Web or Desktop; the README states that the `0.2.2-rc.2` plugin supports DSH `0.2.2-rc.1`, `0.2.2-rc.2`, and `0.2.1-rc.2` through `0.2.1-rc.5`
- Desktop and Web use separate profiles, so the plugin must be installed into each profile separately
Installation steps
- 01
Install into the Web profile: `dsh plugin --profile web add github:omdsh-dev/dsh-sidechain`
$ dsh plugin --profile web add github:omdsh-dev/dsh-sidechain
- 02
For the Desktop profile, start Desktop once to finish initialization, quit it completely, then run `dsh plugin --profile desktop add github:omdsh-dev/dsh-sidechain`
$ dsh plugin --profile desktop add github:omdsh-dev/dsh-sidechain
- 03
Restart the corresponding DSH Web or Desktop after installing or updating
- 04
Alternatively use the plugin marketplace: enable the custom marketplace under 插件 → 实验性插件 → 更多, then add the index source `https://omdsh-dev.github.io/dsh-sidechain/index.json` under 发现 → 添加索引源
Verify the integration
- Type `/` in DSH — the native command menu should list `/btw` and `/side`, with icon, name and description following DSH's system language
Rollback
- Uninstall with `dsh plugin --profile web remove @dsh-external/dsh-sidechain` (replace `web` with `desktop` for the Desktop profile)
03DSH integration and capability boundaries
DSH plugin installed into a web or desktop profile (`dsh plugin --profile web add github:omdsh-dev/dsh-sidechain`) that registers the `/btw` and `/side` slash commands and opens forks in DSH's native sidebar
`/btw` one-shot side question
a question passed to `/btw`→a one-shot answer produced in the background while the main conversation keeps running
`/side` persistent fork with inherited context
a question passed to `/side`→an independent thread in DSH's native sidebar that can keep receiving follow-up questions
the fork stores its messages and tool activity in its own thread instead of the main conversationSide-conversation tool allowlist (`readOnlyTools`)
a list of tool names in the plugin's `config.readOnlyTools`→only those tools are available to side conversations; other calls are intercepted
blocked tool calls are dropped for the side thread while the main session keeps working`/side list` child-session listing
the direct child sessions of the current session
04Who is it for? When not to use it?
Good for
- DSH users who do not want to pollute the main thread just to check one fact
- People who need follow-up questions on the same topic without derailing the main session
- Teams that want read-only side chats over a live repository
Not for
- The README pins the supported DSH versions per plugin release: `0.2.2-rc.2` of the plugin supports DSH `0.2.2-rc.1`, `0.2.2-rc.2` and `0.2.1-rc.2` through `0.2.1-rc.5`, and the index only lists the most recently published plugin version.
- `/btw` is only read-only inside the Sidechain UI; DSH still stores it as a resumable child session, so other clients or direct API calls can continue it.
05Compatibility, maintenance and safety notes
- The README pins the supported DSH versions per plugin release: `0.2.2-rc.2` of the plugin supports DSH `0.2.2-rc.1`, `0.2.2-rc.2` and `0.2.1-rc.2` through `0.2.1-rc.5`, and the index only lists the most recently published plugin version.
- Both commands require a question, and a fork only inherits completed conversation turns — content that is still being generated is not included.
- `/btw` is only read-only inside the Sidechain UI; DSH still stores it as a resumable child session, so other clients or direct API calls can continue it.
- Desktop and Web use separate profiles, so the plugin has to be installed into each one; `/side list` also shows every direct child session, not only the threads Sidechain created.

06Frequently asked questions
How do I install DSH Sidechain into DeepSeek Harness?
Install it into the profile you actually run: `dsh plugin --profile web add github:omdsh-dev/dsh-sidechain` for Web, or start Desktop once, quit it completely, then `dsh plugin --profile desktop add github:omdsh-dev/dsh-sidechain`. Restart the matching DSH Web or Desktop afterwards. You can also add the index source `https://omdsh-dev.github.io/dsh-sidechain/index.json` under 发现 → 添加索引源 and install from the custom marketplace.
What is the difference between `/btw` and `/side` inside DSH?
`/btw` is designed as a read-only one-shot Q&A that runs in the background, while `/side` opens a thread you can keep asking follow-up questions in. Both appear as tabs in DSH's native sidebar and inherit the main session's completed history; neither writes its messages into the main conversation.
Can I limit which tools a side conversation may use?
Yes. By default a side conversation inherits the tools available to the current DSH session. Set `config.readOnlyTools` on the plugin (for example `read`, `grep`, `glob`) to whitelist tools for side conversations; calls outside the list are intercepted by the plugin and the main session is unaffected, while DSH's sandbox and approval policies still apply.
How do I uninstall it, and which DSH versions are supported?
Uninstall with `dsh plugin --profile web remove @dsh-external/dsh-sidechain`, replacing `web` with `desktop` for the Desktop profile. Per the README, plugin `0.2.2-rc.2` supports DSH `0.2.2-rc.1`, `0.2.2-rc.2`, and `0.2.1-rc.2` through `0.2.1-rc.5`, and the project index only lists the most recently published plugin version.
