@0x_MrFive 哈哈哈,来个英文版试试

@Cato_KT 12月加息都定价到84.6%了，今晚PCE数据要是没往上走，反而算利好吧？

[Alan Liu @hexalan]

@EcomSkii For most DTC brands the honest answer is nowhere. The email list they never bothered to build is the only channel they'd actually own.

[Alan Liu @hexalan]

@oliviaakory 0.64x in Q4 is a rough number for something Meta switches on by default right before BFCM. Was the gap worse for brands with small catalogs?

[Alan Liu @hexalan]

@northbeam Does the drop hold if you split accounts by spend tier? I'd guess the big accounts feeding Meta more conversion data are taking most of that 33%.

[Alan Liu @hexalan]

@MartinSzerment The subcontractor point is the interesting part. Does Fusion show which model handled each step, or does that stay hidden once you pick Max?

[Alan Liu @hexalan]

@Ananth7e Hard to get excited about a #1 model when the only people who can use it are cyber defenders. When do regular devs actually get it?

[Alan Liu @hexalan]

Harvard looked at millions of work events and found coding agents raised PRs by 23% while review time went up 49%, and completed tasks didn't move. So who is going to review all this code?

[Alan Liu @hexalan]

@Asteri_eth Does the audit ever recommend splitting a subagent out, or does it only ever fold things back into the main loop?

[Alan Liu @hexalan]

@undefinedKi Making the agent output the list of files it actually opened and diffing that against the input catches this faster than any prompt rule.

[Alan Liu @hexalan]

@abelanger5 @hatchet_dev Asking someone to explain the code their agent wrote is probably the best filter left, the weak ones can't say why it picked that approach.

[Alan Liu @hexalan]

@rcmisk Show HN converts well but it also punishes anything that reads like a landing page, so did you end up rewriting the copy for that room anyway?

[Alan Liu @hexalan]

@johnmcclure00 Most advertisers can't even see which reseller served a given creative, so what would a CISO actually audit here beyond sellers.json?

[Alan Liu @hexalan]

@rentierdigital Skill packs make this worse since people install ten at once, I'd want the agent to list every instruction it plans to follow before the first tool call.

[Alan Liu @hexalan]

@eMeRiKa Makes sense since cold email is one of the few channels where a small tool can prove ROI in a week, which makes it easy to sell.

[Alan Liu @hexalan]

@Nonosam2 Cost per merged PR is the number I watch. A cheaper agent that needs two extra review rounds ends up costing more of my time.

[Alan Liu @hexalan]

@stretchcloud The orchestrator deciding what to delegate is the expensive part to get right, a bad split and the cheap workers just redo each other's work.

[Alan Liu @hexalan]

@BabaDev_ With $500 I'd put it all into Apple Search Ads on exact match keywords, Meta needs more than that just to get out of the learning phase.
