I build terminals and the machinery around them, mostly in Rust and Zig. The thread through most of it: an agent is a first-class user of a terminal now, not something you paste output into. That changes what the terminal has to be.

phux    _rust A terminal multiplexer, like tmux — shells live in a background server, you split them into panes, you detach, everything survives. The difference is what a pane is: a real terminal emulator inside the server that anything can attach to, so the bundled TUI, a shell script, and an agent all hold the same live pane. It records its own demos too — phux rec, no asciinema, no ffmpeg.

phux-cockpit    _zig A native macOS spatial runtime for phux — up to 32 terminals in one GPU surface, each owning its own PTY, emulator, and scrollback, arranged as a pane tree per tab. A single resolve() over that tree is the only source of truth for geometry, shared by the painter, the hit-test tree, and the PTY sizing pump. Splitting, focusing, and resizing never restart a process.

token-tach    _zig A macOS menu-bar tachometer for coding-agent token burn. It reads the session ledgers your agents already write — no proxy, no account, no telemetry — and turns them into an instrument: limit-weighted tokens/minute as the needle, a predicted wall-clock time you hit a limit, projected from the slope of the vendors' own utilization numbers rather than guessed capacities, and a per-agent split so the number resolves into which one is spending it.

phbv    _go A terminal UI for beads. It talks to the bd CLI exclusively over bd … --json and never touches the Dolt store underneath, with golden tests pinning that boundary — so a bd upgrade fails CI instead of silently breaking the UI.

cyrs    _rust A compiler front end for Cypher and GQL: lex, parse, type-check, lint, format, and lower to a logical plan IR. It deliberately stops there — executing the query is the database's job. Ships as a library, a CLI, and an LSP server.

fella    _zig Network containment and identity rotation for hostile networks. All traffic is forced through a WireGuard tunnel inside a dedicated netns with fail-closed iptables; identity artifacts rotate per session. Most tools in this space are shell scripts wrapped in sudo — this one compiles, cross-compiles to bare metal, and has real integration tests.

• phui — my fork of ghui by Kit Langton, which is his tool and worth your star. I've added an Actions dashboard, Inbox/Stars/Projects surfaces, and handoff into phux, and I ship standalone binaries through the tap.
• opentui-browser — a Chromium surface for OpenTUI over the Kitty graphics protocol
• opencode-worktree — Claude Code-style -w worktrees for OpenCode
• silent-weights — embedding and extracting payloads from model weights, for AI supply-chain security research
• dotfiles — chezmoi-managed substrate with a dot-doctor health check
