A developer's Clash and a CI runner's squid both export HTTP_PROXY and its siblings. Now that the harness honors them, an ambient value decides test outcomes: this PR has already recorded a proxy's 502 page as a snapshot's expected output, and let a runner's own export stand in for "what the user exported" in an assertion about inherited names. A Vitest setup file clears the proxy names before any suite runs, wired into every configuration that declares a setup. Real-API e2e is cleared too: before proxy support existed every request connected directly and that suite passed, so direct is the environment it is known to work in. `NODE_USE_ENV_PROXY` cannot be cleared this way — Node samples the proxy environment at process start — and the module says so. A proxy application never exports it, and the eight names one does export are fully handled: with all of them set, the affected suites pass. The wiring is what regresses, so that is what the test pins. Configurations are discovered rather than listed, because the web suites carry no setup today and a hand-written list would let one of them gain a setup without gaining this one. `plugin.spec.ts` kept its own copy of the eight names to guard against the machine; it never sets a proxy variable itself, so the setup replaces that entirely. `install.spec.ts` had one assertion waiting on a DNS miss with no deadline, which timed out once under 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.
