Google engineer: “Just delete your IDE—you don’t need it anymore. Ask Claude Code to run Claude Code for you. 85% of PRs at Google are already shipped by AI agents. If you aren’t building the harness around your agents, it’s crazy how far behind you are.” In this 90-minute... talk, a Google engineer with 30 years of experience explains what the future of AI engineering will look like. Worth more than 10 paid agentic engineering courses. Watch it today, then read the article below to learn how to build a harness for reliable, self-improving AI agents.show more

Bro really wants us to delete our IDEs and trust Claude Code to run Claude Code like we're playing AI Russian Roulette with production

when 85% of PRs ship through agents, the scarce resource becomes harness design and review bandwidth, not typing speed

“85%”这个数字我会先打个问号，但 harness 这件事确实躲不开。我们试下来，agent 写得快不等于合得快，回滚和验收才是最费时间的地方。

The harness is the real product. Agents that open a PR are easy to demo. Agents that don’t quietly wreck your repo without a human in the loop are what people actually pay for.

Let’s all listen to it today, the whole village

this is how ai engineering is changing fast

When agents write their own tests, coverage means the agent was consistent, not that it was right. Had a currency rounding bug in my finance app with full test coverage because the agent had tested its own wrong behavior.

the harness claim matches what i see, though a harness is less glamorous than the word suggests. for us it is two plain files per repo: how to behave here, and what is still left. boring context is what keeps workers from wandering.
