Lifting the single-in_progress cap makes a list shape reachable that the web surfaces never received. Two sites derived their one-line summary with todos.find(t => t.status === 'in_progress') — the collapsed TodoPanel header and the todo_write row — which was total under the old cap and silently dropped every active item but the first once several could match: a plan with three running tasks collapsed to the name of one. The expanded list was always correct, so neither PR's tests covered it. Both sites now take planSummary in contract/todo-plan-model.ts, the domain-shared face both the skeleton and toolviews domains may import; the duplicated derivation was why one find could be fixed while the other stayed wrong. The hint names the first active item and suffixes +<n> for the rest, so the collapsed line reports how many tasks are running. The web fixture's todo sample now runs two items in_progress, so the assembled web transcript replays a parallel plan: the row reads '1/4 已完成 · 实现 fixture 样本 +1' over the built bundles.
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.
