Ion

Ion is a terminal coding agent. The intended experience is a Pi-like minimal surface:

$ ion

> fix the parser bug

This repository is a clean-sheet Rust rewrite. Print mode can run one scripted turn. The last Go implementation is tagged last-go and is not a design, behavior, or migration reference.

cargo run -p ion -- -p hello

RuntimeController can submit, stream, cancel, and shut down a scripted print-mode turn. Tools, sessions, and the TUI are not built yet. Current work lives in ai/brief.md and tk ready.

• AGENTS.md — durable session rules
• ai/brief.md — current head, ready task, next action
• ai/DESIGN.md — working Rust target
• ai/research/ — imported product, TUI, and protocol research
