OutputCollector.spillAll ran openSync/writeSync inside the stream 'data' listener with no containment. When the private per-process spill directory had been removed by a temporary-file cleaner, the first overflowing chunk threw ENOENT from Pipe.onStreamRead, became an uncaught exception in the Desktop Host, and the Electron shell reported it as a fatal failure. Spilling is best-effort by contract (spillPath is optional; a failed final close already withholds it). Every filesystem failure while opening or appending the spill file now discards the spill, reports once through the owner's logger, and leaves in-memory collection untouched. Spill inputs move into one SpillOptions object with the reporter, so tail-only collectors no longer pass an empty directory; prepareManagedProcessBinding is the explicit resolve step for the directory and reporter defaults, and the runtime and SSH helper supply their plugin loggers. Tests cover ENOENT on open (removed directory), ENOTDIR on open, and ENOSPC on append after the file exists, asserting the tail stays byte-exact, the spill file is withdrawn, and the reporter fires once.
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.
