WispAn agent that stays in sync with you

Redirect it while it works. A reliable harness — typed events, explicit approvals, and a transcript you can inspect — keeps you and the agent on the same page.

Quickstart

How it stays in sync

GitHub

Wisp — a glowing spectral companion encircled by an orbiting ring

Steer mid-flight

RPC and SDK clients can queue a correction while the agent is running. Steering redirects the active run without rewriting the transcript; follow-ups wait their turn.

Cancel without losing the thread

Cooperative cancellation stops the run cleanly and leaves the session resumable, not corrupted.

Approvals you control

Mutating and command tools stop for approval. The decision stays outside the model's reach.

Nothing happens off-screen

Every action is a typed event with an enforced order, persisted to an inspectable JSONL transcript.

One runtime, with you in control

Wisp is a coding agent for interactive work, scripts, and integrations. Its TUI, print mode, JSONL RPC process, and Python SDK share one typed runtime, including the same session, approval, cancellation, and event contracts. Each interface exposes the controls its input model can support: RPC and SDK clients can steer live runs, the TUI queues interactive follow-ups, and print/JSON modes are one-shot.
