Cursor launched Projects for Persistent AI Coding Teams: coordinator, thousands of subagents, months of shared context. Migration tip that stuck: review each PR closely early, then review less once it holds. 6x merges is the headline. Quieter review is the tradeoff. #aicoding #devtools

Claude Code can spin fresh sessions from your iPhone onto a connected machine now. Handy for kicking a task off away from the desk. The agent still runs on your box. The review still waits for a real screen. #aicoding #devtools

Vibe coding is back in the promise vs pitfalls debate. Karpathy's original post described accepting diffs without reading them, then steering with prompts. Speed is real. The pitfall is still merging a PR you never opened. #aicoding #devtools

It worked on my machine. Yeah. A Mac. The little “agent is thinking” icon is sitting on the toolbar. Now I get to fix that overlap on Windows and Linux.

The live split on agent PRs is "read every line" vs "don't bother". Both pure forms fail on a 5k-line dump. Serious move: check tests, auth/money boundaries, and failure modes first. Open the code only where those go quiet. #aicoding #devtools

The hard agent bugs aren't messy junior code. They're clean, confident architecture that was never the right design. Looks intentional, costs more later. #aicoding

Some codebases are ~99% written by agents now. That does not make review optional. It makes the person still reading the diff the whole team. #aicoding #devtools

People keep saying "code was never the hard part." Agents made half of that true: generation got cheap. What didn't get cheap is putting your name on a 5000 line PR you barely read. #aicoding #devtools

Claude Code just shipped cross-session messaging. Sessions can hand findings and status to each other mid-task, great for parallel worktrees. Just remember: agents coordinating behind the scenes still produce two diffs you have to read. #aicoding #devtools

Not reading agent code only works if the agent can't quietly rewrite the checks. Tests it didn't write, sandboxes, policies. Without that, green CI is just a demo that passed. #aicoding #devtools

Some numbers going around: teams are shipping about 4x more code with AI agents but only about 10% more delivered value. Review time is up about 441%, and merges going out with zero review are up about 31%. The bottleneck moved, it didn't vanish. #devtools #aicoding

There's a live debate over whether T3 Code should drop plan mode. The pitch was always "review the plan before the agent touches code." But if it's the first thing people cut, maybe the real checkpoint was never the plan, it's the diff you get after. #aicoding

Saw a rule going around: past ~1500 lines, a diff from your agent isn't reviewable anymore, no matter how careful you are. Not a trust problem, a working memory one. Break it into chunks you can actually hold in your head, or you're rubber stamping.

opus 5 dropped — the pitch is near-fable intelligence at half the price. same day, 'uncle bob stops reading AI-generated code' trends at 10k posts. those two headlines together are the whole story: generation keeps getting cheaper, judgment doesn't.

Claude Opus 5 came out today. One headline feature: it's better at catching hazards specific to your own codebase, not just generic bugs. Quiet admission, the risk was never generating the code, it's the diff nobody reads before it merges.

Every agent summary sounds finished: 'refactored for clarity, all tests pass.' The diff is where that story falls apart, usually a couple lines quietly doing something nobody asked for. I stopped reading the paragraph and started reading the diff instead. #aicoding

There's a stat going around: ~96% of devs say they don't fully trust code an agent writes, but only ~48% actually verify it before merging. Talk skeptical, ship on autopilot. The bottleneck isn't writing code anymore, it's trusting it enough to hit merge.

The agent says done, all tests pass. Then I open the diff it actually wrote and start squinting. Every. Single. Time. #aicoding

the translation model was technically not wrong.

A booking form month dropdown in Spanish listing Marzo, Abril, then 'Puede' where 'Mayo' (May) belongs, then Junio, Julio, Agosto. The month May was machine-translated as the Spanish modal verb 'puede'.

Been thinking about why "have the agent check its own work" doesn't hold up. It's the same weights that made the mistake, now grading it. The only real signal comes from outside: a test it didn't write, the compiler, or someone actually reading the diff.

running a bunch of agents at once, tabs stacking, context gone, no clue what each one changed. got tired of guessing, so i built my own terminal for it 👇
