@jasonqq/dsh-btw-plugin
A Codex-style /btw command for DeepSeek Harness.
/btw <question> answers a side question in a sub-context seeded with the main conversation, and shows the answer in the chat without ever adding it to the main conversation's model history. Ask "by the way…" questions freely — the main context stays clean.
How it works
- The command is registered through
@deepseek-ai/dsh-commands(the same
registry that powers /compact, /goal, /plan).
- The question is delegated through
ctx.subagents.start("fork", …). The
fork provider spawns a child agent seeded with the parent's completed turns, so the side question is answered with full knowledge of the main conversation.
- The child's answer is returned as a plain command result. Command results are
rendered by the UI adapter and never enter the model history — that is the "no pollution" guarantee.
Usage
In any session composer:
/btw <question>The answer appears as a command result card. It does not become a message the main model sees, so you can reference it yourself without bloating the context.
Install
The plugin ships as a Cordis plugin and plugs into any profile that mounts @deepseek-ai/dsh-commands and @deepseek-ai/dsh-subagent (both are part of the shipped @deepseek-ai/dsh-base composition).
- Make the package resolvable from the profile, e.g. link it into the shared
profile store:
mkdir -p ~/.dsh/profiles/node_modules/@jasonqq
ln -s "$PWD" ~/.dsh/profiles/node_modules/@jasonqq/dsh-btw-plugin- Add it to the profile patch layer (
~/.dsh/profiles/<profile>/cordis.patch.yml):
- insert:
- id: btw
name: @jasonqq/dsh-btw-plugin
config:
provider: fork The profile patch is read at boot. In the desktop app, restart the app after editing it (the CLI dsh web runner hot-reloads its patches).
Configuration
| Key | Default | Meaning |
|---|---|---|
provider | "fork" | Subagent provider. fork seeds the child with the parent's completed turns (sees the main context); spawn starts a fully standalone child. |
maxDepth | (unset) | Optional recursion-depth cap for the child; defaults to the harness default when omitted. |
Development
npm testThe tests exercise the handler with a stubbed ctx.subagents seam — no live model or host is needed.
