User Manual
Harness of AI is a meta-agent orchestrator for VS Code: one sidebar for Copilot, Claude, Cursor, Devin, and Kiro, with shared file context and Spec-Driven Development (SDD).

On first configuration, the welcome screen summarizes what you get in one place:
| Feature | Description |
|---|---|
| Unified chat | Copilot, Claude, Devin, Cursor, and Kiro in the same panel |
| Shared context | Right-click → Add to Harness of AI Context |
| Specs (SDD) | Skills, Tools, and Workflows in .harness/specs/
|
| MCP | External tool servers |
Click Get started → to configure agents, or Skip and configure later. The wizard ends with this User Manual step before you finish setup.
Everything happens in one interaction surface — no copy-paste between tools:
- Explorer or editor → right-click → Add to Harness of AI Context
- File chips appear above the composer; the same context is sent to whichever provider you pick next
- + New chat — new thread, keeps context
- Clear context — removes file chips only
- View title → Clear Chat & Context — full reset
Providers: Auto, Copilot, Claude, Cursor, Devin, Kiro.
Copilot modes: Ask | Agent | Spec+Agent.
