A DomainSpec may declare compatibleVersions: older domain versions whose stored records the current record schemas still accept. The json backend's per-record reads admit documents stamped with a declared version (writes always stamp the current one), and the legacy whole-unit bootstrap migrates only a file whose stored version is in the accepted set — previously it migrated any version and stamped the records current, turning a discardable stale cache into invalid-record failures that refused the whole domain at open and permanently poisoned the new tree on first boot. A DomainSpec may also declare invalidRecords: 'backup-and-skip' for domains whose records are disposable derived data: a stored record failing its zod schema is moved aside through the new optional KvUnit.backupRecord (<key>.json.bak.<YYYYMMDDHHmm> under the json backend), logged with its cause, and skipped, instead of rejecting the open. The default stays fail-loud, and so do backends without backupRecord. |

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.
