Repository: https://github.com/ClausYang/dsh-bang-shell
Package: @omdsh-dev/dsh-bang-shell
Description
dsh-bang-shell adds Claude-Code-style ! direct shell execution to the DeepSeek Harness Web composer: a message whose first non-whitespace character is ! runs as a shell command in the current session workspace — it is never sent to the model, spends zero tokens, and settles as a durable command card (stdout / stderr / timeout & signal markers / exit code) visible across tabs.
While typing, the composer switches to terminal colors from the first ! keystroke: an amber prompt glyph plus green command text, no background tint, light/dark theme aware.
It supports:

!command interception at Enter adjudication (leading-whitespace tolerant, inline ! never triggers)
Host execution through the session's ctx.shell executor (timeout + sandbox policy inherited)
Empty ! keeps the draft with an actionable error

Install
Requires a DSH core that includes the ! trigger extension (TriggerChar gains '!'; detectTrigger recognizes it; InputMachine routes ! drafts into adjudication — roughly 20 test-first lines in packages/client/ui-input-trigger and packages/client/ui-conversation).
dsh plugin --profile web add /path/to/dsh-bang-shell

Restart dsh web, then refresh the browser.
License
BSD-3-Clause.
Maintenance status
Actively maintained; initial release v0.1.0 (dual-face plugin: host /bang command + browser ! trigger source), 6/6 unit tests, verified end-to-end on a live dsh web at 127.0.0.1:3080.
Known risks / limitations

Depends on the core ! trigger extension; the browser half stays inert on DSH builds without it
Output renders through the generic command card; no dedicated terminal block yet
No shell history expansion (!!); the whole draft submits as one command line
Commands inherit the deployment's sandbox policy — a danger-full-access profile executes ! commands unsandboxed, same as the model's bash tool
