Mount every external bundle layer as a cordis:contained-group entry `bundle/<package>` whose rows carry a `<package>/<id>` prefix, so one community bundle that no longer loads records a failure in the root `pluginFailures` registry instead of rejecting the whole Loader transaction, and two bundles may declare the same row id. Classify layers by origin (`builtin` for the template bundle and `dsh.profile.firstParty`, `external` for profile dependencies) and let `dsh.bundle.stage: boot` or `dsh.profile.stages` opt a bundle out of isolation when it provides a service built-in rows inject; a built-in row left pending beside an isolated bundle still fails boot and names the bundle. Keep `installFailLoud` for the boot transaction only and install runtime guards afterwards: an unhandled rejection is reported and contained, an uncaught exception is reported and exits. Report nested fiber failures under built-in entries as advisory lines. Provide `ctx.profileRuntime` from the launcher (layers with trust and stage, row origin, user-disabled rows, recomposition through the root include) and probe installed packages in a child process (`probePackage`, cached under `profiles/<name>/.dsh-plugins/`). Split installation from enablement in `reconcileInstalledBundles`; the CLI keeps install-means-enable. The plugin inventory now reports `trust`, `package`, `disabledBy`, and `failure` per row and lists rows only the failure registry knows.
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.
