Wrap spawn and the fd-3 narrowing so a synchronous throw (ENAMETOOLONG on an over-PATH_MAX pythonBin, EMFILE) removes the run's staging directory and resolves the same worker-exit class as the async error event, instead of rejecting run() and leaking the directory. Aggregate native stdout/stderr by real newline rather than by Node data chunk: logs entries are joined with "\n" downstream, so a newline-free write larger than one pipe read no longer reads back with spurious breaks. The ledger still bounds a newline-free flood. Track a running scan offset in both frame readers so a large frame accumulated across chunks is scanned once, not re-scanned from 0 per chunk. Reword the deadline hard-bound v8-ignore to state its real environment dependence (PID-1-doesn't-reap container, zombie survivor) and cross-ref the note's rejected signal-0 alternative; fix settle comments that quoted the pre-qualification teardown contract; document the capMessage vs _cap_message billing split on both sides; guard the dispose-after-resolve heartbeat assertion against a vacuous 0===0 pass; reuse _TRUNCATION_MARKER_BYTES; note the abandoned-call pending-entry bound. Update the Agent Note Decision/Testing/Alternatives/Consequences for the above and record the confirmed-empty finalize as a second honest fail-before exception; sync the zh pair.
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.
