VS Code extension

Package: efvibe.vscode-efvibe (v0.3.1+). Source: vscode-extension/.

Install

Build the CLI from the repo (includes efvibe serve), then package the extension:

dotnet build src/MyEfVibe/MyEfVibe.csproj
cd vscode-extension
npm install
npm run package
code --install-extension "vscode-efvibe-0.3.1.vsix"

Reload the window after install. See INSTALL.md for Cursor and update steps.

Fast Run Selection (efvibe serve)

By default, Run Selection talks to a long-running efvibe serve process instead of starting a new CLI for every query. The EF project is built once; the same DbContext stays loaded — much faster for iterative work.

Set efvibe.useDaemon to false to force one-shot efvibe -e per run. Point efvibe.toolPath at a local myefvibe build if the global tool does not yet include serve.

Details: efvibe daemon design doc.

Result panel

With efvibe.resultDestination set to panel (default):

• Editable expression — change parameter stub values and re-run
• Run — evaluate again (Ctrl/Cmd+Enter in the textarea)
• Run :plan — EXPLAIN / SHOWPLAN for the query (--with-plan)
• Export CSV / :export JSON — save the last result (same idea as REPL :export)
• Read-only guard — blocks SaveChanges, Add/Update/Remove, ExecuteSql, and destructive SQL
• Result table, captured SQL, metrics, and warnings in a split tab beside your editor
• 📋 Copy — floating copy on SQL, query plan, and scalar result blocks

Scan Review (carousel)

efvibe: Scan Workspace runs efvibe scan lite or deep and opens a review tab — one finding at a time:

• Previous / Next — browse findings (arrow keys when the panel is focused)
• Location — click the path to jump to file and line
• Dismiss and Note — same JSON stores as REPL :dismiss / :note
• 📋 Copy on code, translated SQL, and query plan blocks
• Optional efvibe.scan.problemsPanel for Problems squiggles (default false — avoids C# LSP noise)

Repository snippets

Select handler LINQ (with await, DbContext, parameters) and run — the CLI adapts the snippet before evaluation. Edit stubbed values in the panel (e.g. replace Guid.Empty with a real id) and re-run. See repository snippets for limits.
