🧠 Workspace Intelligence Agent (WIA) — VS Code & Antigravity IDE Extension

WIA for Visual Studio Code & Antigravity IDE is an AI-powered code intelligence companion providing in-editor symbol impact CodeLens, interactive sidebar agent chat, live subsystem architecture visualizers, and grounded AI reasoning over your entire repository.

⚡ Core Features & Views

1. 🤖 Interactive Sidebar Agent & Chat (`wia-agent-view`)

Laya JEV (Jaccard-Edit-Vector) Router: Instantly classifies natural-language queries into canonical WIA commands or routes conceptual questions to grounded AI reasoning.
Pure Natural-Language Interface: Type natural questions without requiring slash-command syntax.
Quick-Action Chips: One-click shortcuts for Architecture, Dependencies, Doctor Diagnostics, and Status.
Interactive Markdown & Cards: Rich rendering for impact analysis, caller lists, code blocks, and direct file jump links.
Content Security Policy (CSP): Fully compliant and sandboxed for fast, reliable interaction.

2. 🔍 In-Editor Symbol Impact & Flow CodeLens

Automatically analyzes classes, functions, and methods across Python, TypeScript, JavaScript, Go, and Rust.
Inline clickable CodeLens indicators:
- ⚡ WIA Impact (<symbol>): Calculates direct callers, importing modules, and refactoring risk classification (LOW, MEDIUM, HIGH).
- 🔍 Trace Flow: Traces execution call chains starting from that function.

3. 🏛️ Architecture & Subsystems Visualizer (`wia.architecture`)

Interactive visual panel displaying:
- Component boundaries and roles.
- Circular dependency cycles detected via DFS cycle analysis.
- Fan-in and fan-out metrics with click-to-open file navigation.

4. 💥 Refactoring Change Impact Inspector (`wia.impact`)

Deep-dive panel evaluating downstream ripple effects before refactoring:
- Risk classification badges (HIGH, MEDIUM, LOW).
- Direct callers and dependent modules.
- Affected test suites and execution paths.

5. 🌲 Activity Bar Tree Views

🏛️ Architecture & Subsystems: Hierarchical component tree.
🔍 AST Symbol Explorer: Indexed classes, functions, and global symbols.
📦 Dependencies & Imports: Manifest dependencies, missing packages, and conflict indicators.

6. 🔒 Multi-Provider AI Credentials via SecretStorage

Store API keys securely in OS-level credential vaults (VS Code SecretStorage).
Seamlessly switch between OpenRouter, NVIDIA NIM, OpenAI, Anthropic Claude, Google Gemini, and Local Offline Mode.
