The Windows coverage lane grants DSH_COVERAGE_TEST_TIMEOUT_MS=90000, but two paths declined it. scripts/install-lefthook.spec.ts took a describe-level 30_000, restated as a per-case constant on five cases. Every case drives spawned Git and Node subprocesses; the slowest costs 7.5 s on an idle host, so the ceiling carried roughly fourfold headroom and fired on branches that did not touch the file. The suite takes 90_000 and the redundant constant is removed. coverageTestTimeoutArgs raised --testTimeout and --expect.poll.timeout but left --hookTimeout at Vitest's separate 10 s default, which removeFixtureSafely's documented 10-second Windows retry window meets exactly. Raising only the test budget would move a contended suite's failure into its teardown.
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.
