Control surface for
AI-native engineering

A native macOS app that wraps Claude Code sessions with structure, observability, and deterministic enforcement. The cockpit, not the runtime.

macOS 15+ Apple Silicon Requires Claude Code

Decisions govern context. Context scopes agents. Gates enforce decisions.
The graph is the product.

What it does

Everything in one surface

Multi-Session Control

Run and monitor multiple Claude Code sessions simultaneously. See status, token usage, and blocked states at a glance without switching windows.

Decision Graph

ADRs and PDRs as first-class objects with typed relationships, machine-parseable constraints, and immutable status lifecycles. Not just markdown files.

Context Derivation

Automatically generates scoped CLAUDE.md files from the decision graph. When you scope an agent to a directory, the right context is injected.

Deterministic Gates

Test, lint, and compliance checks as first-class objects with triggers and scopes. Failures trace directly to the decision that created the rule.

Session Interpretation

Blocked-state detection, milestone classification, and cross-session conflict detection. Know what each agent is doing and when it needs you.

Native Performance

Rust core + SwiftUI shell. GPU-accelerated rendering. No Electron. No web wrappers. Built for Apple Silicon.

Navigation model

Three levels of zoom

Zoom 0

Intent

Sessions as cards showing theme, status, and recent activity. Idle and blocked sessions surface first for exception-driven monitoring.

Zoom 1

Control

Tiled interactive terminals. All sessions visible and updating simultaneously. Hands-on multi-session work.

Cmd + \ to toggle

Zoom 2

Focused

Single-repo deep workspace with tree view, file tabs, terminal panel, diffs, and content rendering.

Under the hood

Built to be fast

Shell Swift 6, SwiftUI Native macOS UI
Bridge UniFFI Generated bindings
Core Rust 2024 Parsing, watching, git, sessions
Terminal SwiftTerm (fork) Performance-tuned PTY
Git libgit2 (vendored) In-process, no shell-out

Ready to take control

Local-first. No cloud. No telemetry.
