The worktree service now records each checkout it creates as a `plugin:worktree/created` record, folds them in its own `worktree` projection with fork-aware ownership, and reclaims a clean, unreferenced checkout when the Session that created it is archived. The Forge panel reads the service's record and forwards its cleanup state; it no longer writes a `created` record, owns a retention projection, or gates every Session's directory access. Admission registers the attempt inside the Workspace write queue and returns; inspection runs afterwards, reading cold Sessions through the projection cache when mounted and from their log otherwise, with subagent children of an archived ancestor counted as archived. Only a path being removed holds `working-directory/access`, whose request now carries the access's `signal`, and listeners withdraw before the drain. Ignored files no longer retain a checkout, matching Git's non-force removal; processes and terminals are not consulted. The Forge bundle mounts one `worktree` service: the `forge-worktree` row and the `optional-forge-panel` group that isolated a second service are gone, and `forge-panel` is a top-level row. `canRemove`, `remove`, the `forgeWorktreeRetention` projection, and `ForgeWorktreeCleanup` are removed; `WorktreeService.cleanupOf`, `WorktreeCleanup`, and the `worktree/cleanup` Host event replace them. The upgrade guide moves to the current version directory and covers the id removals.
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.
Community and support
- Submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
Contributing
See CONTRIBUTING.md.
Development
Start with the development guide and architecture documentation.
pnpm run dev:web builds, serves, and rebuilds client bundles on source edits in one terminal, and make help lists the matching Make targets for Web and Desktop; the guide's application commands section owns the full table.
For agents, follow AGENTS.md.
