Publish order exists to make a partial publication self-consistent: an interrupted run should leave a prefix whose packages never point at a version absent from the registry. It read only dependencies and optionalDependencies, so peer declarations — how sibling harness packages reference each other, 1088 edges in the dsh family — constrained nothing. Peer edges now order the publication too. devDependencies still do not: a dev dependency is absent from the published package. Peers cannot constrain it absolutely. Sibling packages declare each other as peers, which is what closes the two cycles here, and npm treats an unmet peer as a warning rather than a resolution failure. Install edges therefore win: a peer edge is dropped where the peer installs the member declaring it, or where following it would revisit a member already being visited. One peer edge is dropped in the dsh family and two in the vendored family; every install edge is honoured. A cycle among install edges stays a defect rather than something to order around, and release:verify now reports it before the build instead of letting it surface once pack is already writing tarballs. Install-edge acyclicity is checked on its own graph, because a peer edge leading into an install edge otherwise reads as a cycle where the install edges are perfectly orderable.
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.
Developer preview
DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI, served at http://127.0.0.1:3080 by default. 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
