The previous commit moved the OTLP exporter to the SDK's `fetch` delegate and refused `exporter.compression` at load, on the belief that nothing shipped enabled it. `packages/bundle/base/cordis.patch.yml` does, so the refusal broke every test that boots the shipped bundle — the snapshot, e2e, and Windows observational jobs all failed on that one load error. Dropping gzip was the wrong trade anyway: a realistic OTLP batch measures 6.4x smaller with it, so trading it for proxy support would have charged every deployment to fix one. The `fetch` transport has no compression hook, but serialization is the seam before the body reaches it — the plugin now gzips there and declares `Content-Encoding` itself. `keepAlive` and `httpAgentOptions` have no such seam, since they configure a connection pool `fetch` does not expose, so those two stay refused at load rather than accepted and ignored. `compression` is typed as the two values this package can actually apply rather than the SDK's wider enum, and a third value fails loud at load.
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.
