slipstream

A tool that makes AI coding agents more effective for Dart and Flutter projects. AI agents working on Dart and Flutter run into two recurring problems. First, their training data has a cutoff — they'll reach for discontinued packages, pin outdated major versions, or produce subtly wrong API signatures that compile only after a correction loop. Second, Flutter development is inherently visual and stateful, and agents have no way to see a running app: they can't observe a layout failure, verify that a state change took effect, or confirm that a navigation worked. This tool addresses both. It adds hooks that catch stale package choices before they land in `pubspec.yaml`, an MCP server that retrieves accurate package API signatures directly from the local pub cache, and a suite of MCP commands for launching, inspecting, and interacting with a running Flutter app.
