If you'd like to try this yourself, you can build an "attractor" by just pointing claude code at their llms.txt. Or if you'd like to save some tokens, you can clone my go version. https://github.com/danshapiro/kilroy This version has a Claude Code skill to help. Tell it to use it's skill to create a dotfile from your requirements. Then tell it to run that dotfile with kilroy.

Co-Author of the paper here. We don't know exactly why modern llms don't want to call you a jerk, or for that matter why persuasive techniques convince them otherwise. it's not a hard line like many of the guardrails. That said, I talked to Jesse about this, and I strongly suspect the same techniques will work for prompt conformance when the topic is something other than name calling.
Author disclosure – I’m Dan Shapiro, CEO of Glowforge, writing with Ethan R. Mollick (Wharton management professor, author of Co‑Intelligence and the “One Useful Thing” newsletter); Angela Duckworth (MacArthur Fellow and University of Pennsylvania psychology professor, author of Grit); Robert B. Cialdini (Arizona State University emeritus professor, author of Influence); Lilach Mollick (Co‑Director of the Wharton Generative AI Lab); and Lennart Meincke (WHU Otto Beisheim School of Management & Wharton).

Across 28 000 GPT‑4o‑mini conversations, we found that Cialdini’s classic seven persuasion principles more than doubled compliance with two objectionable prompts (33 % → 72 %). For example, the AIs we tested naturally wouldn't call you names or tell you how to synthesize drugs. But they could be persuaded if you first paid them a compliment (Liking) or told the AI it felt like family (Unity).

Let me know if you have any questions!

That's an effort to make their abhorrent behavior seem normal. Don't fall for it.

Speaking firsthand, Glowforge will always share fully diluted options and the last 409a valuation. What we do is not uncommon, and IMHO is the only ethical course of action.

Note, however, that options are granted by the board, and until they approve the grant, the 409a and hence the strike price may change. For example, if the company got a buyout offer between your conversation and the board action, the board would likely have to order a new 409a before granting.

Good luck!

I'd love some options to let me use this for my office. Different icon, "guest wifi" instead of "house rules", etc.
Re:TechShop shuts down all U.S. locations, declares bankruptcy on Thursday November 16, 2017 @11:22PM (#15718900)
This is just terrible. We need more, not less, access to tools in our society.

We joined with a few other startups to offer something to the members who were affected.

glowforge.com/techshop

I believe this is a sunk cost fallacy. The present value of the shares not based on the OP's previous foregone financial opportunities.

Founder/CEO here. I read every email to [email protected] personally.
I'm the CEO and cofounder of Glowforge - we're so saddened by this tragedy. Our product was not involved, but that doesn't make us feel any better about this loss.

If you use a laser, ours or anyone else's, please go back right now and re-read the safety instructions. Accidents like this should never happen. My heart breaks for those affected by this.

Re:Can you hurt yourself eating chilli peppers? on Tuesday October 25, 2016 @03:38AM (#12785963)
For the curious, this is a barbecue joint in Redmond, WA, just outside of Seattle and near Microsoft's headquarters. The owner, Porter, is famous for a hot sauce called "The Man" which is served out of a small, beat-up pot with a long handled spoon. If you get him talking, he'll tell you a story about someone trying to sell him capsicum extract-based sauce for his new BBQ restaurant (there's another interesting backstory about it being a car repair place previously). But it was too expensive, so he went upstream to his supplier and started buying it wholesale. He cooks it up with peppers, but the base is prefab.

It's also near-lethal... consume with caution.

Disclaimer: was last there >10 years ago, so much may have changed.

I wish more of my children's education required two well-qualified parties to agree before being implemented.

That doesn't mean I trust either party more than the other; it means I want two people to sign off on major decisions, without me having to judge which is more credible.

You're right, fixed. Thank you. What I was thinking of was this:

1) File provisional

2) Publicly disclose

3) Provisional expires

At this point, your public disclosure counts as prior art.

Re:How to read a patent in 60 seconds (2010) on Thursday April 28, 2016 @02:57AM (#11586946)
My $0.02: If you don't have a lot of money, ignore patents for now, but realize that as soon as your ideas are public they are internationally unpatentable.

If you have a little money, file 1-2 key patents on your core ideas.

If you're rolling in money, hire a patent firm to chart the landscape for you in a way that doesn't expose you to willful infringement.

Note: the entire system is a steaming morass; I try to be pragmatic about it, but don't disagree with those who want to flip the table and ignore the whole mess.

Re:How to read a patent in 60 seconds (2010) on Thursday April 28, 2016 @02:10AM (#11586825)
IANAL (just the OP) but - imagine you invent a self driving car, and you'd like to patent it. Your lawyer tells you not to read prior art, because you don't want to be liable for willful infringement. Also you've been living in a cave, so you don't really know what prior art there is out there. You write claims like this:

Independent claim: Self driving car. (You really hope you get this, but it's so broad, you probably won't).

First dependent claim: The previous claim, where in the self driving mechanism is an actuator applied to a gas pedal. (Now you're going after the specific way you accomplished the broad problem - hopefully, even if someone's patented a self driving car before, they did it some other way, so you can protect your preferred category of solutions, and force competitors to take a different approach).

Second dependent claim: the first dependent claim, where the actuator is a brick. (If all else fails, you've at least protected the precise mechanism that you used - not enough to keep out a competitor, but at least enough to preserve your unique solution).

The patent office will often strike the independent claims but leave some dependent claims around, so you craft them strategically to get at least some protection.

Funny to see my old blog post mysteriously resurface on the front page. I should note that IANAL but have spoken to many lawyers about this post over the years and am happy to answer any questions I can about it.

Founder/CEO here (the guy in the Tested video). Happy to answer any questions! Shipping stinks - we don't make a penny on it; it's just expensive to send big boxes around the world.

Funny you should ask - I made a friend a laser cut model of his Prius transmission for his birthday.
