goal-session rides retry turns and survives admission failures. A recovery policy closes a goal round's failed turn and reopens its history under a retry trigger; the attempt now adopts that turn and drops the failed turn's provisional reason, so the round settles from the retry's own outcome instead of blocking an armed goal with turn-error after a successful response. A downstream admission hook that throws (rather than blocks) used to strand the queued reservation forever; the listener now clears a still-turnless matching attempt on the rejection path and reschedules the round. agent-loop contains a persistently rejecting step close in the catch path the same way the finally contains the turn close, so the post-finally tail always publishes the terminal status — previously a double veto escaped run(), leaving status at running while whenIdle() resolved. The whenIdle catch arm is annotated as the backstop it now is: every driver rejection path is contained today. workspace-context folds an already-appended baseline from the session log when the plugin is hot-remounted over a live session, instead of injecting a duplicate from its fresh mount-local guard. The TUI's reference-admission discard listener installs before followup(): admission runs synchronously inside it on the common path, so a listener installed afterwards missed its own cleanup and leaked one callback per referenced prompt.
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.
