Review findings applied across the group: - storage hub: stale disposers no longer remove a successor registration; the package now default-exports the Storage service class per the service-package export shape. - json backend: failed publishes roll back the authoritative memory state (a rejected write can no longer resurface via get() or ride the next publish); close() drains in-flight writes and blocks in-flight opens; double-open rejects as a plain caller error instead of malformed-medium. - sqlite backend: loadAll builds records on a null prototype (__proto__ keys round-trip instead of polluting), user_version is stamped only after the schema is fully created, and corrupt record JSON rejects as malformed-medium instead of a bare SyntaxError. - domain form: writes persist before mutating authoritative memory or emitting; DomainChanged is a put/deleted discriminated union. - workspace: attach/detach idempotence decided on the write chain (stale snapshots no longer short-circuit), create() requires a directory, and startup fails loud on duplicate stored paths. Eleven regression tests pin the fixed behaviors.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source coding agent built on the DeepSeek Harness SDK.
It uses an architecture where everything is a plugin.
Install
Install dsh with one command:
curl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh
The installer requires git and Node ^22.19 || >=24, offers to install pnpm when it is missing, and prompts for a DeepSeek API key.
The installer clones DeepSeek Harness to ~/.dsh/source, links dsh into ~/.local/bin, and launches it. Re-running the command updates the checkout. See scripts/install.sh for alternate install locations and other options.
Use DeepSeek Harness
Web UI
For the recommended local interface, build the frontend after installation and after each update, then start the Web UI:
pnpm --dir ~/.dsh/source run build && pnpm --dir ~/.dsh/source run build:web
dsh web
The Web UI is served at http://127.0.0.1:3080 by default.
TUI
Start the full-screen terminal interface:
dsh
Headless
Run one task, print the final answer, and exit:
dsh -p "summarize this workspace"
Why DeepSeek Harness
Built-in capabilities cover file reading, editing, and search; shell execution; reusable skills; task tracking; subagents and workflows; persistent sessions; and context compaction. The TUI also includes Plan Mode.
- Everything is a plugin. Models, tools, policies, storage, context management, and interfaces are composable Cordis plugins, so deployments can extend or replace behavior without forking the agent loop. See the architecture for the underlying design.
- Code Mode (opt-in). It exposes a
run_codetool and a generated TypeScript SDK; only program output re-enters model context. See Code Mode. - Self-referential Cordis tools are opt-in. They let the agent inspect its live runtime and mount or unmount plugins while it runs. See the Cordis tools.
