* fix(agent-instructions): budget the user-global and project chains separately The user-global and project instruction files shared one maxBytes and the user-global files were the broadest, so a large project chain omitted them first. Each chain now renders under maxBytes on its own and the results share one system-reminder frame: unchanged output when everything fits or one chain is empty, at most twice maxBytes otherwise. The project chain keeps its omit-broadest-first, truncate-last rule; reconciliation batches follow the same split; the maxBytes key and the baseline identity are unchanged. Tests cover the fast paths, both chains fitting only separately, each chain over its own budget, the 2 × maxBytes boundary at exact and tiny limits, multibyte content, reconciliation batches, and a resumed single-budget baseline receiving the user-global file as one transition. The agent-instructions-budget snapshot is refreshed and agent-instructions-budget-chains is added. README, Config.maxBytes JSDoc, the configuration catalog, a new Agent Note, and an upgrade guide state the per-chain bound. * fix(agent-instructions): keep loaded order in merged frames and note the unshared chain budget A merged frame now lists sections, omissions and truncations in the loaded order, so a reconciliation batch renders its items in one order whether or not it fits a single budget. The guard comment states only the invariant and points to the Agent Note; the intro selection states its rule. The README names the unshared budget between chains. --------- Co-authored-by: ZiyaZhang <[email protected]>
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.
Contributing
See CONTRIBUTING.md.
Development
Start with the development guide and architecture documentation.
pnpm run dev:web builds, serves, and rebuilds client bundles on source edits in one terminal, and make help lists the matching Make targets for Web and Desktop; the guide's application commands section owns the full table.
For agents, follow AGENTS.md.
