<p>Hi, thanks for posting this. I appreciate you not coming from engineering and being laser focused on product building.<p>There's a real gap identified (execution permission instead of output guardrails). The timing concern is valid (we're scaling agent framework way faster than security infrastructure — see Clawdbot-Moltbot). The default-deny + time-boxed permissions + audit logs is a solid model, easy to discuss at high-level with security teams in an org. The "Auth0 for AI Agents" framing is clear and positions it well.<p>Actually, the audit log piece is really huge. Having a complete execution trace with authorization decisions is invaluable for incident response. That alone might justify adoption even if the blocking mechanism is imperfect.<p>My concerns and questions:<p>- Where exactly does this sit? If it's between the agent and tool calls, that's relatively straightforward. If it needs to intercept arbitrary code execution or API calls, that's significantly harder.<p>- Adding another authorization layer means more setup, more policy configuration, more potential points of failure. Adoption challenge.<p>- Who defines what's "allowed"? In what format? How granular? Actually expressing "this agent can do X in context Y at time Z" in a way that's both powerful and usable, that's the whole ballgame (IMHO). I have in mind how complex AWS IAM policies got, and those are for relatively static systems. AI agents are dynamic, context-dependent, and probabilistic.<p>- By the time Reg sees a request to execute, the LLM has already decided. What happens when you block it? Does the agent gracefully handle denials and retry with different approaches?<p>I'd be interested in seeing real-world policy examples from your design partners. That'll tell you whether you've found the right abstraction layer.<p>Congratulations for just framing the idea and getting this far. Being very concerned about the current free-wheeling AI expansion with minimal security, I strongly believe this is going in the right direction and would like to know where this leads.</p>

<p>Can you provide non-anecdotal evidences for your first statement?<p>Because it's fairly easy to do so for the opposite statement.

<p>Actually, "esprit d'escalier" is indeed used in French, though less commonly, especially outside of literary contexts. It refers specifically to the inability to come up with a timely response or comeback (and the frustration of finding the "perfect" reply when the conversation is already over). On the other hand, "présence d'esprit" has a broader usage in everyday language. It can mean having a quick and witty response (the opposite of "esprit d'escalier"), or more broadly, the sudden ability to judge and react appropriately in a situation.<p>edit: typo</p>

<p>It's very good. I've tried it after hesitating a bit because of the price tag compared to Khan Academy — no regrets.<p>K.A. is great and I still use with my kid, but M.A. is more condensed and to the point for my needs. I was properly guided through the first program choices according to my profile, and the diagnostic exam you start with was perfect to highlight what I <i>actually</i> need to work on given my limited time.<p>Explanations and courses are super condensed, with the right amount of example and pedagogy that clicks for me.</p>

<p>It goes even deeper than getting laid if you study Costume History and its psychological importance.<p>It is a powerful medium of self-expression and social identity yes, deeply rooted in human history where costumes and attire have always signified cultural, social, and economic status.<p>Drawing from tribal psychology, it fulfills an innate human desire for belonging and individuality, enabling people to communicate their affiliation, status, and personal values through their choice of clothing.<p>It has always been and will always be part of humanity, even if its industrialization in Capitalistic societies like ours have hidden this fact.<p>OP's POV is just a bit narrow, that's all.</p>

<p>Lobbying?<p>As a secular Jew in Western Europe, I've distanced myself from my religious community due to its insistence on tying my identity to Israel. Where I live, it's less taboo to critique Israel than in the U.S., but still tricky.<p>Advocates of Israel's right-wing politics have blurred the line between criticizing Israel and anti-Semitism, an endeavor helped by actual anti-Semites. I've grown up with these supporters, but can't quite call them a "lobby" due to their loose organization and lesser influence here compared to the U.S.<p>Speaking out brings risks: being labeled a leftist extremist, clashing with fellow Jews, or unwittingly aiding anti-Semites. And that's <i>if you are Jew</i>.<p>This creates a pervasive, cautious silence that I imagine is even more stifling in countries with highly organized pro-Israel lobbying.</p>

<p>>It might be time to lose that space, similar to how we don't double space after period.<p>Well, that's is a bit like saying "it might be time to write <i>your</i> whenever you mean <i>you're</i>" just because Google Docs' autocorrect feature kept messing up the two when you wrote English.<p>How would it look like in an email to a client?</p>
