DSH Orbit + Browser Plugins

Community plugins for DeepSeek Harness (DSH). Not affiliated with or endorsed by DeepSeek.

This monorepo publishes two independent Cordis plugins:

Package	Role
@kasenri/dsh-orbit	Deterministic engineering orchestration (orbit_controller tool + OrbitService).
@kasenri/dsh-browser	Controlled browser automation (agent_browser tool + BrowserAutomationService).

Orbit is a deterministic engineering orchestration runtime for DeepSeek Harness. It coordinates planning, execution, evaluation, bounded correction, runtime recovery and durable state through a minimal Commander / Executor / Smart Watchdog architecture. Orbit 强调的是一个“有界、自我收敛的工程执行轨道”：

PLAN → EXECUTE → EVALUATE → CORRECT / RECOVER → SUCCESS

Orbit is not a timer loop, an infinite auto-continue, a pure reviewer, a pure planner, or an agent swarm. It is a deterministic supervisor plus Commander, Executor, Smart Watchdog, durable state and bounded recovery.

The two packages are decoupled: the browser plugin is a shared capability and Orbit works without it. Only a plan step that declares the browser capability needs the agent_browser tool to be registered.

Requirements

Component	Tested with
@deepseek-ai/dsh	0.1.5-rc.2
@deepseek-ai/cordis	4.0.2
agent-browser (browser plugin)	0.33.2
Node.js	>= 22.19.0

DSH is in developer preview; the plugins are tested with the versions above, not with every future DSH release.

Install

Both packages are published to the npm Registry. pnpm must be on PATH.

# Orbit plugin only
dsh plugin --profile web add @kasenri/dsh-orbit

# Browser plugin only
dsh plugin --profile web add @kasenri/dsh-browser

# Both (Orbit browser-capability steps may then use the browser plugin)
dsh plugin --profile web add @kasenri/dsh-orbit
dsh plugin --profile web add @kasenri/dsh-browser

The dedicated Git distribution mirrors (github:KasenRi/dsh-orbit and github:KasenRi/dsh-browser) track the mirror repository HEAD and remain available when a Git source is preferred; the source monorepo's versioned GitHub Release tarballs remain for manual or offline installation.

Each package declares a dsh.bundle manifest, so dsh plugin add installs it and registers it as a profile layer automatically. See the package READMEs for configuration:

• Orbit configuration
• Browser configuration

Quick start

The most deterministic way to start Orbit is the slash command:

/agent-orbit 修复当前项目的 TypeScript 错误并运行测试

Orbit supports three activation styles:

1. /agent-orbit <goal> — deterministic slash-command activation (Web GUI slash menu, or a genuine user message gesture on headless/CLI surfaces).
2. orbit模式 — recommended natural-language activation.
3. cx模式 — legacy compatibility; still resolves to Orbit.

In the Web GUI an Orbit model control sits immediately left of the native model seat: Commander/Watchdog persist into DSH settings, and the Executor follows the current session model through the same shared model directory. Each new run snapshots the three effective routes; resumes keep their frozen routes.

# Orbit (typed tool, the same entry the slash command activates)
orbit_controller { "action": "run", "goal": "…", "approved_loop_count": 4 }
orbit_controller { "action": "status" }

# Browser
agent_browser { "args": ["open", "https://example.com"] }
agent_browser { "args": ["snapshot", "-i"] }
agent_browser { "args": ["click", "@e2"] }
agent_browser { "args": ["snapshot", "-i"] }

Safety

• Orbit: read-only allowlists for Commander and Watchdog, a writer allowlist for Executors, browser tools only for steps that declare the capability, single-mutation-owner fencing, bounded corrections and loop budget, and recoverable guard denials that stop one tool call instead of the run.
• Browser: page-scoped refs and stale-ref blocking, tab-drift detection with a single deterministic recovery, artifact verification, protected browser state blocking, credential redaction, strict allowedDomains containment, and no CAPTCHA/OTP/2FA bypass.

Migrating from CX

See packages/orbit/README.md. In short: dsh-cx → dsh-orbit, cx_controller → orbit_controller, CX mode → Orbit mode, ctx.cx → ctx.orbit. .cx/state.json remains unchanged, legacy cx模式 remains supported, and existing durable runs do not need migration.

Development

npm install
npm run typecheck
npm test            # unit tests
npm run test:e2e    # real Cordis host end-to-end
npm run test:smoke  # real Chromium / CDP / Orbit browser smokes
npm run build       # emit lib/ for both packages

The test suite covers unit, runner-integration, real-Cordis-host end-to-end and real-Chromium smoke levels. The DeepSeek Orbit smoke (npm run smoke:deepseek) requires real model credentials and is not part of the default suite.

Distribution mirrors

This repository is the canonical source monorepo. The npm Registry carries the primary release; the installable Git sources are the generated release mirrors KasenRi/dsh-orbit and KasenRi/dsh-browser. Do not develop features in the mirrors. After the release tests and npm run build pass, sync an explicit stable version with:

npm run sync:distribution -- 0.5.6 --push

The script copies only each package's package.json, cordis.patch.yml, README.md, LICENSE, and prebuilt lib/. It updates mirror main and creates a missing package-version tag; ordinary development commits never publish to a mirror automatically. Versioned tarballs in this repository's GitHub Releases remain available for manual or offline fallback.
