RepoPrism

VS Code / Cursor extension (M-030 shell + M-031 full dashboard). Loads @repo-prism/core in the extension host and renders the Prism app (Overview, Map, DNA, Domains, Blast, Trends, Settings) in a webview.

Marketplace id: prismhq.repo-prism (packaged as unscoped name repo-prism — see PUBLISH.md).

Commands

Open in Browser starts a loopback HTTP bridge (http://127.0.0.1:17321) over the same @repo-prism/core session the extension already indexed — no second Vite playground process. Works in F5 and installed builds.

The IDE webview itself is not a public URL; the bridge reuses the same UI bundle and Core RPC.

Develop

# from repo root
bun install
bun run --filter @repo-prism/ui build
bun run --filter @repo-prism/vscode-extension build

Then Run Prism Extension (F5) via .vscode/launch.json.

The build stages better-sqlite3 under dist/node_modules with an Electron prebuild (PRISM_ELECTRON_VERSION override supported).

Package / publish

Platform-specific VSIX (ships the correct better-sqlite3 native binary):

bun run --filter @repo-prism/vscode-extension package:vsix
# or explicitly:
cd packages/vscode-extension && bun run scripts/package-vsix.ts --target darwin-arm64

Targets: darwin-arm64, darwin-x64, linux-x64, linux-arm64, win32-x64.

Sideload and Marketplace / Open VSX steps: PUBLISH.md.

Architecture

• Extension host → @repo-prism/core only (PrismSession)
• Webview → playground-parity screens + @repo-prism/ui map; data via postMessage RPC
• Open file paths in the editor from Map / host openFile messages
• No network by default; opt-in integrations and local git via Core when available
