Minimal Omni

Keep DeepSeek Harness minimal by default. When a task needs a browser, documents, or code navigation, Minimal Omni lets the session request that capability and release it when the task is done.

English · 简体中文

Minimal Omni is an independent Developer Preview for DeepSeek Harness. It does not replace the official Web app or change your provider settings.

Why use it?

	A large tool setup	Minimal Omni
Tools visible at idle	Many, depending on the setup	pwsh, str_replace_editor, request_capability, release_capability
Browser	Always present or configured separately	Requested only when needed
Documents	Depends on the setup	Requested only when needed
Planning or reviewer prompts	Depends on the setup	None added by this package
Uninstall	Varies by setup	One DSH plugin command

The model remains the official Minimal brain. The surrounding runtime supplies the tools and cleanup; it does not add a planner or a review loop.

Install

Run this once in the DSH environment you already use:

dsh plugin --profile web add github:Rainflowers686/deepseek-harness-minimal-omni#v0.2.0-preview.2

The command adds one bundle to the existing web profile. It does not change the default preset, provider, model, credentials, proxy, or permissions.

Use

Start the normal Web profile:

dsh --profile web

Create a new session, open Agent preset, and select Minimal Omni. Standard and other installed presets remain available.

For a coding task, the idle surface stays small. If the task needs a current web page, a PDF, or repository navigation, the session can request Browser, Documents, or Code/LSP for that task and release it afterwards.

Uninstall

dsh plugin --profile web remove @rain/minimal-omni

Removing the bundle leaves the rest of the Web profile and your sessions and credentials in place. Install the pinned command again if you want to return.

What is included

See the capability matrix for the evidence-based support tiers. In brief, this preview includes the Minimal brain, on-demand Code/LSP, Browser, Web fetch, PDF/DOCX/ZIP extraction, Jobs, native Goal and manual /compact, session reload, and an integrated coding path.

XLSX and PPTX model-facing workflows, Goal continuity across a successful compaction, automatic compaction tuning, and optional media extraction are Experimental. Vision is Conditional on the selected route supporting image input. Web Search and authenticated GitHub actions need their own provider or authorization. Desktop automation, ASR, broad audio/video understanding, and cross-Agent handoff are Deferred.

Minimal Omni does not ship a custom 0.68 compaction override as a stable default; automatic compaction tuning remains Experimental.

Compatibility

The tested runtime is dsh-v0.1.2-rc.1 at commit a66e4702047846cdaa10c66c9d3df3951f5ea70d. Windows is the first supported platform. See COMPATIBILITY.md before trying another DSH build.

Security notes

• Capability tools use the current session workspace and bounded output.
• Browser profiles, downloads, screenshots, and jobs are owned by the runtime.
• Known unsupported Vision routes are rejected before an image tool is used.
• Acceptance/CI mode has stricter request and home-isolation checks; normal community use does not require an acceptance ledger or an artificial request budget.
• Do not paste API keys, cookies, or private session logs into an issue.

More detail is in SECURITY.md and TROUBLESHOOTING.md.
