The automation-only rewrite edited many implemented Agent Notes; several edits replaced still-live or historical rationale instead of reframing: - llm-model-catalog: restore the prompt/request consistency section and selection-ownership alternatives — installAgentLlmTarget and the TUI /model selector still ship that design; only the ACP wire is gone. - plan-specific-collaboration-state, acp-multi-session, todo-write, ask-user-question: link the superseding automation-only note instead of silently rewriting the original decision or motivation; drop a paragraph duplicating the Web-provider facts stated two paragraphs up. - sandbox: stop claiming unit coverage for turn-enclosed config writes (that mechanism left with the bridge) and retitle the commit-boundary paragraph accordingly. - Fix the missing blank line before '## Consequences' in the plugin-command-registration pair, the JSON-RPC/Web render-intent consumer misattribution (the second consumer is the host/client runtime), stale bash_output/bash_kill names, and 'optional goals' in architecture.md. - examples/acp-agent/README.md: point at the package contract instead of restating it; packages/ui/permission and plan-mode READMEs record the consumer-less preset service and the exit_plan_mode coverage gap under Known Limitations. - 2026-06-19-acp-snapshot-tests: the new note defers the corpus migration rather than committing to it; say so. Re-record the touched bilingual pairs.
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.
