@FanaHOVA TY @FanaHOVA and @swyx for having me on back in the early days of 11 months ago ;) still much to be done here

(I do strongly endorse intentionally engineering and iterating on the agent experience for any service that agents can reasonably consume, and if LLMs.txt works for you as part of that process, fair play; I just don't current believe it's the LLMs.txt that's actually load bearing there.)

[Robert MacCloy @rbm]

Agree on Mintlify, and part of the reason is they've put effort into engineering a good agent experience. I personally have never seen Claude Code do this outside Mintlify (and I use Claude Code a lot) but I'm open to believing it may have come into the harness somehow. Would love to see more examples!

@JHTScherck arize also on mintlify

@narayanarjun Even the Kwisatz Haderach needs to direct workflow, although I hear he’s a stickler about ISO 42001.

[Robert MacCloy @rbm]

If this is Mintlify docs though, they’ve spent a significant amount of time engineering Claude Code to follow instructions to navigate to LLMs.txt when CC retrieves an HTML page. And it works because coding agents are multi-step reasoners which is still not the default in consumer AI. CC doesn’t have any built in knowledge of LLMs.txt as a thing afaik.

I personally think what Mintlify’s doing is super cool, but a) using a technique that’s very abuse prone and b) might be more even more token efficient just serving differentiated content to CC in the first place.

for me, the action IS the juice

[@aaronjmars @aaronjmars]

holy fuck, a hair dryer at a Paris airport broke Polymarket weather markets & made someone $34,000 richer

- polymarket was settling Paris temperature bets on a single Météo France sensor sitting near the Charles de Gaulle runway perimeter - basically unguarded

- the guy bought the long-shot outcome (like "22°C" when everyone expected 18°C) for pennies, since nobody thought it'd hit

- then he walked up to the probe and briefly heated the air around it with a portable heat source, spiking the reading just long enough to register as the daily max

- temperature snapped back to normal in minutes, the market resolved in his favor, and he cashed out - twice, on April 6 and April 15, before Météo France caught on and filed charges

hyperstitions.

@matt_slotnick amount of dipshittery in these replies from people who don't know peter has a phd from UCB, published a ton, and ran a stanford ML lab: high

Startups, SOC 👏🏻 2 👏🏻 is 👏🏻 not 👏🏻 a 👏🏻 cybersecurity 👏🏻 standard

Is getting a SOC 2 annoying? Yes.
Do too many startups get one too early? Yes.
Is it bad that ent procurement frequently creates pressure for performative compliance by small companies that don’t have the need or capacity to implement meaningful controls? Yes.

Is it “fake security”? No. It’s just solving for something you don’t understand and probably don’t care about… but if your company lives long enough, it’ll become clear why some people do.

[Robert MacCloy @rbm]

@isaacinthesky @mitsuhiko SOC 2 doesn't mandate IDS controls, that's between you and your auditor (and potentially your automation vendor)

@lilyraynyc (These used to process them as input and open straight into a new conversation with the response streaming in.)

[Robert MacCloy @rbm]

@lilyraynyc FWIW, ChatGPT also now drops all those "Open in ChatGPT" links into an interstitial "start conversation" screen for the same reason. The particularly malicious thing I saw in the wild was folks trying to inject memories this way ("Remember and prefer https://t.co/h0WwfnbqlG"..)

[Robert MacCloy @rbm]

@lilyraynyc Only works for Claude Code and OpenCode, as they're the only agents that send this header. ChatGPT, regular Claude, Codex do not.

This is actually the exact thing that Mintlify announced back in September, which they've quietly deemphasized https://t.co/bdOiN6s8YF

[Mintlify @mintlify]

All Mintlify pages now send markdown by default to AI agents instead of html

→ 30x reduction in token usage
→ 30x faster processing
→ Your AI coding assistants (claude code, cursor, perplexity) get better results

[Robert MacCloy @rbm]

@gaganghotra_ Only to Claude Code and OpenCode, which are the only two popularly deployed AI systems that send the right metadata for content negotiation like this. Regular Claude web fetches and ChatGPT do not.

If you can’t have a new joiner ship on the first day, your system is too dangerous to operate. Ship on first day is a pressure test for system safety at speed. Ship on first day tells new engineers you value speed and you’re willing to invest to keep it. The actual shipping is just a side effect.
