VS Code preview

The extension is unfinished. It is not published to the VS Code Marketplace and no prebuilt VSIX is distributed.

Try it from source

1. Build the project.
2. Open the Predictive Debugger folder in VS Code.
3. Press F5 to launch an Extension Development Host.
4. Run Predictive Debugger: Connect in the new window to choose a CLI and verify its sign-in.
5. Run a prediction command below.

Command	What it does
Predictive Debugger: Connect	Pick a CLI and verify live access
Predictive Debugger: Predict Failures in Current File	Analyze the open file
Predictive Debugger: Predict Failures Across Project	Analyze source files across the workspace, including tests

Results appear in the Problems panel and Output > Predictive Debugger. The extension requires a trusted workspace.

Use the Run Extension (bug-patterns test folder) launch configuration to try the project-wide command. Its development host opens a separate fixture folder, since VS Code cannot open the same folder in both windows.

Settings

These are VS Code extension settings. For MCP predictions, pass the tool parameters instead.

Setting	Default	Purpose
predictiveDebugger.claudeModel	CLI default	Model alias for Claude
predictiveDebugger.codexModel	CLI default	Model for Codex
predictiveDebugger.copilotModel	CLI default	Model for Copilot; auto lets the CLI choose
predictiveDebugger.logFile	None	Workspace-relative log file to include in the score
predictiveDebugger.pythonPath	Auto-detect	Python interpreter for log analysis; machine-scoped
predictiveDebugger.multipleFindings	false	Request all demonstrable failures in a file; experimental
predictiveDebugger.maxFiles	25	Maximum files per project run; each requires a model call
