- new cookbook page adding-a-remote-api (en/zh): the five-step HOW-TO for declaring, failing, registering, consuming, and testing a Remote endpoint. - new Agent Note ctx-remote-failure-vocabulary records this round's decisions and alternatives; the 2026-08-02 and 2026-08-10 notes are rewritten to the shipped facts (RemoteError vocabulary, $host, the retired ApiProxy statements). - package READMEs pick up the new failure-face contracts (typert/protocol, api/gateway, api/remotes, test-support/client-runtime), dsh-util-time gains its README and registry entries, and stale connection/WorkspaceError/legacy-code statements are corrected (ui-settings, ui-settings-models, workspace-controller, docs/subsystems/typert incl. the TypertGatewayErrorCode type-equiv block). - packages/AGENTS.md gains the Remote-failure rule bullet; its doc budget rises 675 -> 714: the bullet is the compressed remainder after relocating detail to the cookbook and the Agent Note.

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.
