The review's arithmetic checks: the closing-frame walk used cap logBudget - openCost, so a compliant merged entry (58-byte wire cost under a 64-byte budget) could see a negative cap and truncate; the first-fragment cap used logBudget instead of the ledger's logBudget - 1, so an open frame costing 63 was admitted with a bill of 64, pushing the ledger negative and letting a subsequent empty frame ride in one byte past the configured cap; and the child billed a closing frame as a fresh entry (quotes+separator again) instead of the merged tail, truncating an exact-fit 30+30 entry. Fixes: first-fragment cap logBudget - 1 (matching admit), continuation and closing-frame cap logBudget + 2 (billed without quotes), jsonStringCostUpTo returns undefined below 2 bytes, and the child's split billing keys off _open_started alone (a closing frame pays content only) with the cheaper bound len(text) while a merge is open. Regression cases cover all three arithmetic paths.
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.
