The review's warning: a flushed unterminated line is billed and committed (README wire contract says so), but every truncation arm — the child truncated frame, an over-budget open frame, an over-budget closing frame, and admit's two budget arms — pushed only the marker, dropping the held prefix: the ledger charged for output that vanished. All arms now funnel through truncateLogs(), which pushes the (already billed) held prefix before the marker and clears openParts, so the prefix survives and only the marker stays last; the finish() guard drops the now-dead !logsTruncated check (a truncated run has an empty hold). A regression case asserts [prefix, marker]; the forged-flood and closing-overflow cases now expect the committed prefix plus the marker. |

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.
Community and support
- Submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
