pi-provider-kiro

A pi provider extension that connects pi to the Kiro API (AWS CodeWhisperer/Q), giving you access to 17 models through a single provider.

All models are free to use through Kiro.

Setup

Install the provider:

pi install npm:pi-provider-kiro

Or install via npm directly:

npm install -g pi-provider-kiro

Then log in:

/login kiro

This opens a browser for authentication. You can choose from:

• AWS Builder ID — Native device code flow (works in SSH/remote environments)
• Google — Social login (requires local browser or SSH port forwarding)
• GitHub — Social login (requires local browser or SSH port forwarding)

If you have kiro-cli installed and already logged in, credentials are picked up automatically — no second login needed.

Usage

Once logged in, select any Kiro model in pi:

/model claude-sonnet-4-6

Reasoning is automatically enabled for supported models. Use /reasoning to adjust the thinking budget.

Retry Behavior

Generic transient retries such as HTTP 429 and 5xx are handled by pi-coding-agent at the session layer.

This provider only keeps local recovery for Kiro-specific cases:

• 403 auth races, where it can refresh credentials from kiro-cli
• first-token / stalled-stream recovery
• empty-stream retries
• non-retryable Kiro body markers like MONTHLY_REQUEST_COUNT and INSUFFICIENT_MODEL_CAPACITY

Development

npm run build       # Compile TypeScript
npm run check       # Type check (no emit)
npm test            # Run all 248 tests
npm run test:watch  # Watch mode

Architecture

The extension is organized as one feature per file:

src/
├── index.ts            # Extension registration
├── models.ts           # 17 model definitions + ID resolution
├── oauth.ts            # Multi-provider auth (Builder ID / Google / GitHub)
├── kiro-cli.ts         # kiro-cli credential sharing
├── transform.ts        # Message format conversion
├── history.ts          # Conversation history management
├── thinking-parser.ts  # Streaming <thinking> tag parser
├── event-parser.ts     # Kiro stream event parser
└── stream.ts           # Main streaming orchestrator
