Require exactly two System prompt controls for the unchanged-header resume fixture, and pin the repeated prompt in both collapsed and expanded subagent history. Keep all branch eligibility, disabled action, cancellation, disclosure, and inventory assertions intact. Refresh stale July 25 clocks only where canonical fixture createdAt=0 already selects the seedSession near-now anchor. Preserve nonzero historical timestamps and the existing normalizer: do not conceal calendar differences globally. Update navigation read paths to the recorded workspace subdirectory and omit decode throughput for the zero-duration Bash cancellation stream. Evidence: own frozen install and full build; baseline eight-file replay 10 failed, 37 passed, 3 record skips plus stale question teardown; six-file ARIA refresh 36 passed, 2 record skips; final read-only eight-file replay 47 passed, 3 record skips after separately authored Web fixture prerequisite eaa5277d82. Baseline exact count rejected 2 versus 1 and old date/prompt goldens rejected actual output. No Session generation, helper, runtime, or normalization edits in this commit. Live/question source mismatch is repaired solely by the prerequisite; their passing ARIA and skill goldens stay unchanged.
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.
