# DeepSeek Harness
docs: bilingual docs contract, translation skill, and pairing gate
Establish EN->ZH bilingual documentation for the README and docs tree:
- docs/i18n/README.md — the pairing contract: sibling foo.md <-> foo.zh.md,
English canonical, blob-hash source fingerprints, language switchers,
scope/exclusions, and a manifest-driven rollout ratchet.
- docs/i18n/translation-rules.md — how to translate: faithfulness, structure
preservation, terminology discipline over docs/i18n/terminology.md, and
typography rules grounded in MDN/K8s/Vue/clreq conventions.
- .agents/skills/dsh-translate-docs — the committed agent workflow, following
the dsh-code-review pattern of deferring to docs as sources of truth.
- scripts/verify-translation-pairing.ts + manifest — a doc-sync gate: required
pairs exist; every existing .zh.md is fresh (fingerprint = current source
blob), switcher-linked, structure-matched, and non-orphaned; excluded
(generated) docs stay unpaired. --list prints the translation work list.
- RFC (implemented/process) recording the decision and the alternatives.
- Dogfood: README.zh.md and the two i18n docs translated under their own rules.
Gates: doc-sync green including the new gate; red/green proven for stale
fingerprint, orphan, and excluded-file violations.

DeepSeek Harness (`dsh` ) is an open-source agent harness developed by [DeepSeek AI ](https://deepseek.com ).
2026-07-23 12:15:56 +08:00
2026-08-13 18:26:20 +08:00
It uses an architecture where **everything is a plugin** , and is powered by [Cordis ](https://github.com/cordiverse/cordis ), whose design is described in [_A Programming Paradigm for Spatiotemporal Composability_ ](https://github.com/cordiverse/paper ).

## Developer preview
2026-07-22 10:55:16 +08:00
2026-08-13 12:02:48 +08:00
DeepSeek Harness is currently in _developer preview_ and is iterating rapidly. **THERE WILL BE COMPATIBILITY-BREAKING CHANGES.**

## Run
### Run from `npm`
2026-07-22 10:55:16 +08:00
2026-08-13 12:12:13 +08:00
Install `Node.js` , then run:
2026-07-22 10:55:16 +08:00
```sh
2026-08-12 10:59:06 +08:00
npx @deepseek -ai/dsh web
2026-07-22 10:55:16 +08:00
```
2026-08-14 13:44:36 +08:00
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 ](docs/user/guide/index.md ).
2026-07-23 00:15:44 +08:00
2026-08-12 10:59:06 +08:00
### Run from source
2026-07-23 00:15:44 +08:00
2026-08-13 12:02:48 +08:00
To run from a repository checkout:
2026-07-23 00:15:44 +08:00
```sh
2026-08-12 14:03:34 +08:00
git clone https://github.com/deepseek-ai/deepseek-harness.git
2026-08-12 10:59:06 +08:00
cd deepseek-harness
pnpm install
2026-08-12 11:57:02 +08:00
pnpm run build
2026-08-12 10:59:06 +08:00
pnpm dsh web
2026-07-23 00:15:44 +08:00
```
2026-08-14 13:44:36 +08:00
`pnpm run build` prepares the repository artifacts. `pnpm dsh web` uses those built artifacts without rebuilding.

## Development
Document the architecture and rewrite AGENTS.md
docs/architecture.md: layering, service map, event taxonomy, the
session/turn/step lifecycle, Cordis waterfall semantics, an extension
cookbook, the plugin sanity checklist mapping every MVP feature to its
extension mechanism, and the deferred-work TODO list (sub-agents,
persistence backends, compaction, DeepSeek V4 adapter, parallel tool
execution, streaming-protocol review).
AGENTS.md: repo layout, commands, conventions (dsh-* naming, ESM,
effect-based registrations, declaration merging, waterfall semantics),
and the vendoring policy pointer.
