Coven Pocket

Coven Code in your pocket. An iOS client for the OpenCoven agentic coding ecosystem, built on the same Rust engine as coven-code.

Status: pre-alpha. M0 foundation — Rust engine crates compile for iOS and the spike app streams a completion end-to-end. Nothing here is stable.

What it is

A hybrid agentic coding app:

• Standalone mode — bring your own Anthropic key (Codex OAuth planned). The coven-code engine runs on-device: agentic loop, sessions, memory, diffs, and a sandbox-safe tool profile (file tools; no shell — iOS forbids subprocesses).
• Companion mode (planned) — pair with the Coven daemon on your Mac or server to attach, steer, and approve full-capability sessions remotely.

Local-first, no telemetry, no OpenCoven servers in the path — requests go straight from the device to your provider.

Architecture

app/            SwiftUI app (iOS 17+)
rust/ffi        coven-pocket-ffi: UniFFI surface over coven-code crates
                (claurst-core, claurst-api pinned by git rev)
scripts/        XCFramework + Swift bindings generation

The engine crates keep their upstream claurst-* names (see coven-code's fork notes).

Build

Requirements: Xcode 16+, Rust with aarch64-apple-ios + aarch64-apple-ios-sim targets, xcodegen.

rustup target add aarch64-apple-ios aarch64-apple-ios-sim
./scripts/build-xcframework.sh        # builds Rust core + Swift bindings
xcodegen generate                     # produces CovenPocket.xcodeproj
open CovenPocket.xcodeproj            # build & run the CovenPocket scheme

Rust-only check (fast inner loop):

cd rust && cargo check -p coven-pocket-ffi
