one-agent-one-browser
A from-scratch HTML/CSS browser in Rust, built in about three days by one human directing one Codex agent, with no third-party Rust crates.
The GitHub description calls it a browser built by one human and one agent. The repository README does not name the tool. The author's 27 January 2026 post states that after about a day with Codex the program could fetch and render sites via X11 and cURL, with an empty Cargo.lock.
Human involvement
Person and agent both wrote code. The author set tight constraints (three days, no third-party Rust crates, readable files) and worked with a single agent. This is pair-style direction, not an unattended swarm.
Evidence
- Author blog
After about a day together with Codex, I had something that could via X11 and cURL, fetch and render websites when run, and the Cargo.lock is empty.

Notes
The default git branch is master; fetching README from main returns 404. The exact Codex model version is not named in the post excerpt reviewed.
