How the three nest

A coherent trio, not a portfolio

01

Shell

Aurelian

A workspace-native macOS terminal, forked from iTerm2. It reorganizes the terminal around a workspace — a Workspace Rail (⌘B) that groups sessions by kind, and a Sidecar for context, files, and the one browsing surface. Its warm palette is Twin-Sparrow's design baseline.

02

Engine

Twin-Sparrow

The AI coding-agent runtime and CLI that runs inside that terminal — an 8-package TypeScript monorepo with a hand-rolled TUI renderer (no Ink). Opinionated: agents are processes, not chats; context is a first-class artifact; the runtime is inspectable end-to-end.

03

Bridge

Agent-Adapter

A token-efficient plugin that projects Twin-Sparrow's doctrine into Claude Code and Codex from one host-neutral core — six runtime capsules and a verification gate that inject only the smallest faithful slice per turn. One companion, two activations: Solaris and Atoman.

Three projects

Real versions · real capabilities

01

Aurelian

v3.7 (iTerm2-derived) · Swift / Obj-C / Rust · GPLv2+

"A workspace, not just a terminal."

  • Workspace Rail (⌘B)
  • Sidecar: context · files · web
  • Metal GPU rendering

A workspace-native macOS terminal forked from iTerm2. The mature engine stays; a workspace layer sits on top — sessions grouped by kind, a single contextual Sidecar, one unified browsing surface.

In Development

02

Twin-Sparrow

core v0.65.0 · TypeScript monorepo · pre-1.0

"Agents are processes, not chats."

  • 8 packages, terminal · web · mobile
  • Custom TUI renderer, not Ink
  • MCP + multi-provider layer

The agent runtime and coding-agent CLI. A pure provider layer, a core turn-loop with tools and memory, and the shipped twin-sparrow binary — one runtime reachable from terminal, web, and iOS.

Private · pre-1.0In Development

Agent-Adapter

v0.0.2 · TypeScript, zero-dep core · MIT

"One companion, two activations."

  • 6 capsules + verification gate
  • Claude Code + Codex, one core
  • 71 passing tests

The plugin that lets a host agent speak Twin-Sparrow's doctrine cheaply — injecting the smallest faithful runtime slice per turn. Solaris reflects; Atoman ships. A token ledger that refuses to overclaim.
