tabbit-browser for DeepSeek Harness
English | 简体中文
A plugin for DeepSeek Harness (DSH) that gives the agent control over your Tabbit Browser: real pages, real login state, and real interactions, driven through tabbit-cli — the task-isolated Playwright CLI owned by the browser itself. Use it for web automation, information extraction, QA, and benchmarks.
What you get
| Component | Description |
|---|---|
tabbit-browser skill |
The working guide for browser automation: persistent task spaces, locators and waits, screenshots, receipts and recovery. Discovered and loaded automatically with the plugin — no separate skill install. The model loads it via skill({ name: "tabbit-browser" }) or /tabbit-browser. |
tabbit_browser_install tool |
Environment preflight: detects installed stable Tabbit editions, requires version 1.9.0 or newer, and verifies the tabbit-cli resident runtime. When Tabbit is missing or outdated, it starts a DSH background job that downloads the region-appropriate installer. |
tabbit_plugin_update tool |
Plugin update check: compares the installed plugin version with the published changelog at most once a day, silently skips offline failures, and records a version the user declined. When a newer release exists, the skill loads with an update notice showing what the new version added. |
Installation
1. Check or install DeepSeek Harness
Check whether DSH is already installed:
dsh --version
If the command prints a version number, continue to the next step. If it is not found, install it for your operating system.
macOS
Install Node.js 20 or newer, then install DSH:
brew install node
npm install -g @deepseek-ai/dsh
Windows
Install Node.js LTS in PowerShell:
winget install OpenJS.NodeJS.LTS
Reopen PowerShell after the installation, then install DSH:
npm install -g @deepseek-ai/dsh
Run dsh --version again to confirm DSH works.
2. Install the tabbit-browser plugin
dsh plugin --profile web add dsh-tabbit
This installs the npm package (prebuilt tarball, CDN-served). If the npm registry is unreachable, fall back to the GitHub source:
dsh plugin --profile web add github:Tabbit-Browser/dsh-tabbit
3. Start DSH
dsh web
How it works
After installation, the bundle automatically registers its skill provider. The model loads the skill via skill({ name: "tabbit-browser" }) or /tabbit-browser. Before the first browser operation in a task, the skill calls tabbit_browser_install:
ready— a stable Tabbit edition at1.9.0or newer is installed and the runtime is running; the agent continues with thetabbit-cliworkflow.restart-required— the installed version is sufficient, but thetabbit-cliruntime is not running; the user is asked to restart Tabbit Browser once.background— no stable edition is installed, or none reaches1.9.0; the tool starts a DSH background job that reads the operating system's configured region (macOS reads the system locale, Windows calls the system region API) and downloads the matching stable installer: the domestic build fromtabbit.comfor mainland China, or the international build fromtabbit.aifor every other or unknown region. It selects the right Windows x64, macOS Apple Silicon, or macOS Intel package, saves it to the user'sDownloadsfolder, reports download progress, and notifies the absolute installer path on completion.
The environment check also:
- Treats the runtime as available when multiple Tabbit instances are running; the agent sets
TABBIT_PLAYWRIGHT_INSTANCEfrom the CLI's hint instead of reporting the instance ambiguity as an unavailable runtime. - Diagnoses the DSH sandbox mode required to invoke the CLI on the current platform: Windows reports
cliSandboxMode: danger-full-access, other platforms reportdefault. - Caches a successful environment check per agent session and re-checks only after a Runtime/launcher failure or an installation change, via
refresh: true.
Requirements
- A stable Tabbit Browser at version
1.9.0or newer: either the internationalTabbitor the domesticTabbit Browser— installing either one is enough. If it is missing or outdated, the plugin downloads the installer for you. - The current DSH profile provides
ctx.skills,ctx.tools, andctx.jobstogether with the corresponding model tools. dsh-tool-jobsprovides background job control and completion notifications for the current agent.- The current DSH profile provides a Bash/Shell tool running on the same host machine as Tabbit Browser.
- The shell's execution environment can reach the Browser-owned Runtime Service.
- On Windows, DSH's
read-onlyandworkspace-writerestricted tokens cannot write to the Runtime named pipe. The skill first runs the normaltabbit-cli tasksconnection probe and requests no permission at all when it succeeds. Only when the Browser, launcher, and Runtime processes are all detected but the connection returnsBROWSER_RUNTIME_UNAVAILABLEdoes it ask the user to switch the current DSH session to Full Permission — and it then stops the task immediately, without retrying or continuing browser operations.
Notes and limitations
- Mainland China uses the domestic
tabbit.comdownload source; all other regions use the internationaltabbit.aisource. - The background download reports progress and notifies the absolute installer path when it finishes. It never opens the
.dmg/.exeautomatically. - Development builds are not detected.
- The plugin does not provide native browser tools such as
tabbit_browser_evaluate. - If DSH's Bash runs in a sandbox such as E2B or a remote container that cannot access the local GUI browser, this skill cannot make Tabbit automation work there.
