Yichen Jiang 3b73a415c2 Merge origin/master: RemoteError wire vocabulary and ctx-based preset stores
Reconciled with the scope-grouped plugin list: compositionInventory keeps
its additive block over master's RemoteError refactor; the slimmed
settings-store keeps ctx-based signatures while staying a display-only
roster store (no describeFace, no select); dead transport-rejection tests
dropped with the wire that no longer rejects; module graph, catalogs, and
harnesses regenerated against the merged tree.

DeepSeek Harness

English | 中文

DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.

It is built on an everything-is-a-plugin architecture and 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 in developer preview and 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.

Development

Start with the development guide and architecture documentation.
