Install the IDE extension

Install Prism (extension id prismhq.repo-prism), open a project folder, then Command Palette → Prism: Open Prism.

VS Code

1. Extensions (Cmd+Shift+X / Ctrl+Shift+X).
2. Search Prism, or install from the Marketplace.
3. File → Open Folder… (not a single file).
4. Command Palette → Prism: Open Prism.
5. Wait for indexing (status bar), then use map / health UI.

Cursor

1. Install Prism from Open VSX, or search Extensions. If search lags: Extensions: Install from VSIX….
2. Open your project folder.
3. Command Palette → Prism: Open Prism.
4. (Recommended) Also add the MCP server so the agent and UI share the same analysis.

Requirements

Node.js 26+ for CLI/MCP companions. The extension indexes the open workspace.
