# How McKay Wrigley actually uses coding agents

Founder, Takeoff AI

**If you take one thing:** `"You are AGI-pilled."`, in every agent's system prompt. one line he puts in every agent's system prompt, after two weeks of A/B tests, so agents stop acting as if the world stays static.

- **Agent:** Codex (app) ([source, 2026-04-24](https://x.com/mckaywrigley/status/2047806060061507971))
- **Agent:** Claude Code (cli) ([source, 2026-01-06](https://x.com/mckaywrigley/status/2008637181355847736))
- **Model:** Claude Opus 5.5 ([source, 2026-09-22](https://x.com/mckaywrigley/status/2102447442147086563))
- **Model:** GPT-6 Astra ([source, 2026-09-05](https://x.com/mckaywrigley/status/2096264183482552753))
- **Review:** Approves without reading the code ([source, 2026-01-23](https://x.com/mckaywrigley/status/2014743894840451263))
- **At once:** 9 AI tabs ([source, 2026-02-05](https://x.com/mckaywrigley/status/2019509652099330057))
- **Harness:** Claude Code agent swarms with the multi-agent tmux view ([source, 2026-02-05](https://x.com/mckaywrigley/status/2019557279222439962))
- **Rules file:** CLAUDE.md in his public app template ([source, 2025-06-16](https://github.com/mckaywrigley/mckays-app-template/blob/d605aa5c1a6260c716576e8030b4c0b19ee197ab/CLAUDE.md#L36))
- **Hooks:** ultrathink on prompts ending in -u ([source, 2025-08-04](https://x.com/mckaywrigley/status/1952466679239524624))

## In their words

> codex feels like an engineer (which is great for coding!), whereas claude still feels like a general purpose coworker.

> claude code + opus 4.5 injected the immaculate hacker vibes back into ai that we haven’t had since gpt-4.

> i honestly don’t really see a reason to use another model right now?

> with gpt-6 astra i’m up another 3-4x on token usage.

> my day is just using 9 different ai tabs at once and commanding them to do everything for me.
