Introduction

Wisp is a coding agent that stays in sync with you. Its fullscreen TUI, RPC, and SDK surfaces can steer an active run or queue follow-up work, and every interface uses the same typed runtime rather than a separate implementation.

The harness makes its work observable and recoverable: tool calls pass through explicit safety gates, lifecycle events arrive in an enforced order, and sessions are append-only JSONL records that can be inspected and resumed. These guarantees make Wisp useful both at a terminal and inside long-lived integrations.

Wisp 0.1.0 is the first stable release. While Wisp remains below 1.0, later minor releases may make announced breaking changes under the documented compatibility policy.

Start with Installation and the Quickstart. Then read Staying in sync for the exact steering, follow-up, cancellation, and approval behavior available through each interface. Embedders can continue with the Python SDK.
