A directory row in the @ menu had one verb doing two jobs: picking it
inserted literal @dir/ text and kept the menu open, so a user wanting
the folder itself never got a settled entity — the token kept its
trigger character and stayed editable, nothing like a file's atomic
chip.
Split the intents on the same row, mapped to shell-completion instincts:
row click / Enter settles the directory as an atomic folder chip (the
file chip's exact language; canonical @dir/ mention as its serialized
form — the { insert } arm the folder path never took), while Tab or the
row's trailing chevron drills: literal editable text, menu open on the
children. One new dimension carries it: candidate.drill advertises the
verb, InputTriggerPick.action reports it, ArbitrateKey gains 'tab', and
the keymap intercepts Tab only while a drill row is highlighted.
Covered by controller arbitration, MenuView chevron routing, the
ui-reference verb split, a keymap Tab-passthrough spec, and a real-
browser e2e driving all three gestures; menu golden refreshed for the
chevron and the fixture directory.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It uses an architecture where everything is a plugin, and is powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
Run from source
To run from a repository checkout:
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
Community and support
- Feel free to submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
