Main summary

Key takeaways

Technology

DeepSeek Harness Overview (What It Is)

  • DeepSeek didn’t launch a new chat model or a new conversational AI (not a “V4”-type model and not just a new Chat feature).
  • Instead, it released a local program/tool called Harness that you install on your machine.
  • Harness provides an interface to work with AI alongside your files and terminal.
  • Key idea from the official project page: “Everything is a plugin.”
    • Harness is framed as a plugin-based ecosystem, not a single monolithic product.

What Problem Harness Solves vs. “Just Using ChatGPT”

The speaker contrasts Harness with opening an AI directly inside a chat app:

  • Harness provides an environment composed of plugins, so you can connect the tools you want without being overwhelmed by an all-in-one toolset.
  • It’s described as model-agnostic:
    • You don’t have to use DeepSeek specifically—you can connect other providers and models.

Tutorial: Installing and First Run

Prerequisite

  • Install Node.js from nodejs.org.

Launch via NPX

  • Run Harness using an NPX command (copy/paste into Windows Terminal or your terminal).

API Key Prompt (Optional at First)

  • When you open the provided local/hosted link, Harness may ask for a DeepSeek API key.
  • The speaker chooses to configure later.

Creating a Workspace (and Why It Initially Fails)

  • After launching, you create/select a workspace folder for your project.
  • A greeting/chat attempt can fail if there’s no API key configured yet.

Configuring Models via “Providers”

  • In Harness settings → Models, add an external provider API key.
  • The speaker demonstrates using NVIDIA (described as a free provider):
    • Create an account and generate a key via build.nvidia.com.
  • Notes on rate limiting:
    • Example shown: roughly ~40 requests per minute (described as “infinite AI with a limiter within 1 minute”).
  • Then:
    • Paste the NVIDIA API key into Harness.
    • Select a model (example: DeepSeek V3 Flash).
    • Confirm the chat works.

Harness UI Features Mentioned

Workflow Controls

  • Chat sidebar and common actions:
    • Attach files
    • Compact mode
    • Feedback mode
    • Go mode

Resource / Behavior Controls

  • Visibility and controls for:
    • AI/token usage
    • duration/limits
    • read-only vs. full access
    • whether it asks permission
  • Chat context limit handling
  • Trajectory/history of actions (what happened, who did what, timing)

Project Organization

  • A project sidebar similar to VS Code (files, terminal, etc.).

Usage Modes (Different Capabilities)

  • Standard
    • Broader capabilities like:
      • editing files
      • running shells
      • web search
      • scheduling
      • skills
      • subagents
  • Minimal
    • More restricted—acts mainly as a tool.
  • PTC
    • Exposes an SDK so models can combine operations in TypeScript programs.
  • Creator
    • Intended for creating your own AI workflows/ways to use it.

Plugins: How the System Works

  • Harness settings include pre-prompts (identification/styles for skills/plugins).
  • A Plugins tab lists built-in plugin types such as:
    • Shell
    • Agent
    • Loop
    • Sub Agent
    • Web Search
    • (and more)
  • The speaker emphasizes modularity:
    • skills and plugin components are configurable
    • plugins can be added/edited

Tutorial: Installing the Plugin Marketplace + Extensions

Unlike VS Code, Harness requires enabling its plugin marketplace:

  1. Install PNPM:
    • npm i -g pnpm
  2. Install/use DSH
    • described as letting you run Harness tooling without needing NPX each time.
  3. Install a marketplace package (example):
    • dsh plugin add profile-web-ads-market
  4. Restart Harness:
    • A plugin marketplace UI appears (VS Code-like)
    • browse/discover plugins, themes, install, restart, and enable/disable

Examples of Plugins/Themes Mentioned

  • “Better sidebar” plugin theme/extension:
    • improves sidebar capabilities (more controls, git-related options, more subagent-related tools)
  • A theme/wallpaper integration example:
    • changes UI appearance (Wallpaper Engine-like)
    • can be deactivated by removing/turning off the installed plugin

Cloud Code Integration + Orchestration / Subagents

  • The speaker highlights integration with Cloud Code for developers already using it.
  • They show where to configure Cloud Code:
    • session/installer/usage plan
    • Jira integration
  • They also emphasize orchestration of sub-agents:
    • one model/plugin can call another
    • forming multi-step agent chains

Practical Warning / Review-Style Analysis

  • The speaker repeatedly warns that DeepSeek Harness is still in preview:
    • plugin/version conflicts can break daily use
    • different plugins may require different dependency versions
  • Additional caution:
    • plugins are open source and could be malicious
    • install carefully
