@prism/vscode-extension

VS Code / Cursor extension (M-030 shell + M-031 full dashboard). Loads @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

Command	ID
Prism: Open Prism	`prism.open`
Prism: Open Repository Map	`prism.openRepositoryMap`
Prism: Show Health	`prism.showHealth`
Prism: Reindex	`prism.reindex`
Prism: Open in Browser	`prism.openInBrowser`

Open in Browser starts a loopback HTTP bridge (http://127.0.0.1:17321) over the same @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 @prism/ui build
bun run --filter @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

bun run --filter @prism/vscode-extension package:vsix

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

Architecture

Extension host → @prism/core only (PrismSession)
Webview → playground-parity screens + @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
