Hand fixes for the findings --fix cannot touch, mirroring the fixes already applied on the fe-docs feature branch (same file, same shape) so its eventual rebase resolves cleanly: - restore the return the no-confusing-void-expression autofix ate in useAbsentSnapshot (typed S | undefined; hook call kept for hook-order stability, undefined returned explicitly); - re-type DOM queries the no-unnecessary-type-assertion autofix broke: getByRole<HTMLButtonElement>(...) generics instead of the removed as-casts (the eslint program and the client tsconfig aggregate disagree about these casts; the generic form satisfies both); - justified eslint-disable for the deliberate legacy paths: keyCode 229 IME-composition detection, execCommand clipboard fallbacks, lib.dom clipboard optionality, and the any-typed Reflect.get/this probes in test fakes; - drop the dead react/no-danger directive (eslint-plugin-react is not loaded, so the rule never applied) keeping its shiki rationale; - delete the tautological 'Z' comparison and the renameTarget null check already implied by renameBlocked; - css-module non-null assertions replaced by type widening (Button className, TAG_CLASS Record) per the established pattern; - misc: max-len comment wraps, void generic drop in the deferred test helper, unused type imports, floating selectWorkspace promises voided, member-delimiter newlines in inline type literals.
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.
