Responding to ds-review-bot round 2 on #661: - logWork is bounded: past maxParallelSubCalls pending shaped-append tasks the ordered commit lane holds (Promise.race drains one), so a slow spill backend backpressures the run instead of accumulating unbounded pending I/O and retained results. Tasks self-remove on settlement; run settlement still drains every task inside the open turn. New spill test drives three oversized reads against a hung backend at cap 1 and proves the third dispatch cannot start until a save drains. - shapeDispatchLog's catch uses errorMessage() (total), so a thrown value with a throwing toString cannot escape the containment and lose the settle event. - CodeDispatchLog.content documented as the RENDERED result projection (native tool/result vocabulary), not what the program received — the program gets the structured value; doc pair + type-equiv re-synced. - New RECORDED tui-agent snapshot scenario code-mode-dispatch-spill: the real Loader-visible composition (worker runtime + spill-local + policy) drives an oversized bash sub-call end-to-end; replay proves the durable dispatch copy is bounded to preview + locator while the program value stays whole (the outer result carries just the line count). Agent Note updated (both languages).
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.
