Pi Workflow — VSCode Extension

Integrated UI for pi coding agent workflows. Chat with the agent, track plans, review verifications, and manage multiple workflows — all inside VSCode.

Features

💬 Chat Panel

• Built-in chat interface with pi coding agent (RPC-based bidirectional communication)
• Markdown rendering with syntax highlighting
• Tool call visualization with ANSI color support and collapsible cards
• Streaming response display with thinking indicators
• Input queueing during agent processing

📋 Workflow Sidebar

• Workflow Status — Real-time state tracking across all stages (Planning → Verification → Implementation → Compound)
• TODO Progress — Tree view with per-item status (pending / in-progress / done)
• Changed Files — Git diff tree with per-TODO and per-branch change tracking

📝 Plan & Verification Panels

• Plan viewer with markdown rendering and active TODO highlighting
• Verification results with severity-based color coding (🔴 CRITICAL / 🟡 WARNING / 🔵 INFO)
• Multi-domain parallel verification progress display

⚙️ Workflow Management

• Multi-workflow support — Create, switch, and delete workflows
• TODO rollback — Undo completed TODOs via context menu (git reset)
• Resume context — Implementation notes preserved per TODO for session continuity
• Settings UI — Tabbed settings panel for models, stages, search, and verification config
• Model selection — Provider/model dropdown with per-stage configuration

🔍 Parallel Search

• Multi-query parallel codebase search with configurable scopes
• Scopes: codebase, docs, solutions, web, tests, types, config

Requirements

• VSCode 1.85+
• pi coding agent installed and available in PATH
• Git (for changed files and diff features)

How It Works

The extension spawns a pi process via RPC (pi --mode rpc) and communicates over JSON lines. Workflow state is stored in .pi/workflows/ and synced between CLI and VSCode sessions in real-time.

Workflow States

| State | Description | |-------|-------------| | 📝 Planning | Writing the implementation plan | | 🔍 Verifying Plan | Plan is being verified | | 🔨 Implementing | Code is being written | | ✅ Verifying | Implementation is being verified | | 📦 Compound | Multi-step compound task in progress | | ⏸️ Idle | No active workflow |

Commands

| Command | Description | |---------|-------------| | Pi: Start Chat | Start pi agent and open chat panel | | Pi: Stop Chat | Stop the running pi agent | | Pi: New Workflow | Create a new workflow | | Pi: Open Plan | Open the plan viewer webview | | Pi: Verification Results | Open verification results panel | | Pi: Show Changes | Show changed files with diff | | Pi: Settings | Open workflow settings panel | | Pi: Refresh | Force refresh all views | | Activate Workflow | Switch to a different workflow (context menu) | | Rollback TODO | Undo a completed TODO (context menu) |
