AI IDE Extension

A production-oriented VS Code extension scaffold that provides Cursor-style planning, staged file generation, per-file accept/decline, model and agent selection, command preview/confirm, and streaming AI responses.

About

Brift is an AI coding assistant for VS Code focused on real development workflows, not one-shot code dumps.
It helps you plan tasks, generate and review file changes safely, run commands with approval, and iterate quickly inside your workspace.

Brift supports built-in models plus custom model endpoints, context-aware prompting with @ file attachments, and practical coding modes such as deep thinking and deep search.

Features

• Structured TODO planning before code generation
• Fast planning mode with direct generation flow
• Strict JSON parsing in code mode
• Multi-file and folder proposal preview
• Per-file Accept / Decline and Accept All
• Native VS Code diff preview per file
• Model selector (GPT-4.1, GPT-4.1 Mini, Claude 3.5, Ollama, Custom API)
• Agent selector (Architect, Fast Coder, Refactor, Debug, Test Writer)
• Terminal command preview and explicit confirmation
• Workspace-safe guards for paths, .env, dangerous commands, and config edits
• React + Tailwind webview UI with streaming and token usage indicator

Setup

1. Install dependencies:

npm install

2. Build extension and webview assets:

npm run build

3. Type-check and run tests:

npm run typecheck
npm run test

4. Open this folder in VS Code and press F5 to launch the extension development host.

Configuration

Set provider credentials using Brift Settings -> Models (stored in VS Code SecretStorage), or environment variables during development:

• OPENROUTER_API_KEY for built-in Brift models
• CUSTOM_API_KEY (or configured aiIdeExtension.customApi.apiKeyEnv) for custom endpoint models

Optional settings:

• aiIdeExtension.customApi.baseUrl
• aiIdeExtension.customApi.model
• aiIdeExtension.customApi.headerName
• aiIdeExtension.ollama.model

Safety Rules

• File writes are blocked outside workspace root.
• .env* paths are blocked from AI edit flow.
• Dangerous shell commands are blocked.
• Config file edits require explicit user confirmation.
• Commands are never auto-run.
• File edits are never auto-applied.
