Project status

Minimal Omni is an independent developer-preview plugin loaded through the DSH profile-bundle interface. You continue to use the official Web app. The supported capabilities and runtime pin are documented below.

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 package requires Node.js 22.19+ and PowerShell 7. 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.

Docs and contributing

• Capability matrix: verified, conditional, experimental and deferred capabilities.
• Troubleshooting: installation, presets, browser, Vision and provider problems.
• Development and contributing: local checks and requirements for new capabilities.
• Changelog: changes between preview releases.

Static and packaging checks need no provider key. For a compatibility report, include the DSH and plugin versions, reproduction steps and a redacted error message.
