... team to learn." We had spent so much time building the custom features and doing the manual data imports that we completely neglected the core user experience. The tool was clunky, the UI was confusing, and their team just refused to adopt it. I was so focused on winning the deal that I forgot to make sure the product was actually easy to use for the people who had to log in every day. It was a massive lesson ... ... customers vs

... available to everyone not locked behind the few and that we should be able to depend on our models for accurate, unbiased information. That means building in the open where we can, measuring what models actually do, and refusing to dress marketing up as truth. A big part of why I care about this is emergent behavior: the useful (and sometimes surprising) patterns that show up when systems scale and interact capabilities and failure modes that weren't explicitly programmed ... ... Organization https://FractalResearchOrganizat... @FractalResOrg froresearch@outlook.com Comment from George Basov(@gbasovv): Welcome James. "Measure what models actually do" is the part I can vouch for from the product side. The music model I build on has a safety filter that refuses

... Product Hunt community! Today I'm launching Refuse to Share , a free Chrome extension I've been working on independently. The idea came from a simple question: Why is accepting cookies usually so much easier than rejecting them? We visit dozens of websites, constantly facing cookie banners, and often end up accepting things we never really intended to. So I built Refuse

... added tools. It was rewritten parameter descriptions, 92 of them. The agent reads that text and acts on it. The person approved the server once and never reads it again. mcpgawk sits on that gap: baseline at approval, refuse the call when the surface changes until a human looks. https://mcp.gawk.dev/ph if you want to try it. So: when you add an MCP server to Claude Code, Cursor or Codex, what do you do at its next version ... ... Neelagiri Chettiyar(@neelagiri_chettiyar): @ali_shaheen  Thank you. We do hash the descriptions too .. that's the one thing the call time check is built on. Each tool's description is hashed at approval and the call is refused

... Back in 2013, we co-founded one of the earliest real-time spot market TMS platforms. The platform itself worked, but we hit a massive operational wall: drivers flat-out refused to download another native app. That driver resistance forced us to pivot and build an appless tracking system instead, which solved the onboarding bottleneck overnight. Fast-forward to today, and we see the exact same mistake repeated across B2B, field services, and logistics: forcing operational end-users to install ... ... native apps, remember passwords, or navigate complex portals just to update a status. For makers and developers building B2B software: Where do you draw the line between forcing a native app install vs

... Hello Product Hunt family. Product Hunt family I'm Jaye Hembree, creator of YouAt a privacy-first family location-sharing app I like to call a "better, friendlier, affordable alternative to Life360." The seed was planted 20+ years ago when BlackBerry was still king and I was driving thru a huge shopping complex mumbling to myself: "my wife will NEVER find this car someone needs to build "Where did I park?' with a compass and distance." Fast forward to today ... ... hours later, YouAt is here. One Pixel phone, one laptop, one wife who's non-tech QC was perfect for ease of use and layout design.

... make a request to an address a stranger chooses, so the check on the address is the security of the feature. The first version did what most guides say. Allow only http and https, resolve the hostname, and refuse it if PHP filter flags for private and reserved ranges reject the address. Those flags cover the ranges everyone remembers: 10.x, 192.168.x, loopback, and 169.254.169.254, where a cloud server hands out its own credentials to anything that asks from ... ... over IPv6. So a hostname with a public IPv4 record and a loopback IPv6 record passed the check at registration and again at every send, with no timing trick involved. The fix was asking for both record types and refusing

... request when that variable is not set at all. I expected the answer to be that everything fails. That is what a missing secret sounds like: no key, so no signature can match, so every event is refused, and the worst case is a noisy outage somebody notices within the hour. It is not what happens. An unset variable arrives in most config layers as an empty string, and an empty string is a perfectly valid key to a hash ... ... function. The official library I use takes the secret, computes the expected signature with it, and compares. It never asks whether the key is empty. So with no secret configured, the endpoint does not refuse

... them online. Whatever answers turns up as an ordinary device, with its identity, its history and its alerts. No password, no helper, nothing to install. It stays inside your own subnet, and a range that reaches outside is refused rather than quietly trimmed to fit. That range is also a filter Set it to two addresses and the list shows those two. This is the part that makes the whole thing honest: you can see what it found. While ... ... restart themselves so "it'll come back" would have been wrong about the other 34. It also stopped making you wait Inspecting a port that has closed since the last scan used to spin for the full timeout. A refusal

... question is the safety. There is a second safety underneath it: the console framework checks whether it is attached to a terminal, and if it is not, it marks the run non-interactive, and a non-interactive run refuses instead of applying anything. I read the code this morning to find out why neither of those had ever stopped it. The terminal check only runs if the input object has a stream to test. The ordinary input, the one built ... ... agents and pipelines work in. The check for your own stack: for each command that asks before acting, find its default, then run it against a throwaway database with its input connected to nothing, and see whether it waited, refused

... right and is more useful than either, and the revised version went up this month, so it's worth twenty minutes before you write your Q4 plan. It's NBER working paper 35275, Demirer, Musolff and Yang - "Writing Code vs. Shipping Code." More than 500,000 GitHub developers, matched against their actual AI usage telemetry rather than a survey, in a matched event study design. The headline numbers are large and I have no interest in arguing with them. Cumulative ... ... Their follow-up is more interesting than the original. They ran it again from August 2025 with 57 developers, and published in February 2026 that the design had broken - not because of the result, but because too many developers refused

... enough VRAM. Loading it can crash the tab. The tempting fix was a fallback. If the device is too weak, send the text to a server and return the answer. Two lines of config. Nobody would notice. Every competitor does exactly this, and it would have made the feature work for most of our traffic, since most of our users are on mobile. We made it refuse

... wall of English error prose in the chat bubble. Retrying showed you the same wall. Very helpful. ( #40 ) The twist: Skim never sent reasoning_effort at all. The model reasons at medium on its own, then refuses its own default alongside our tools so nothing in our request even named the thing that broke it. We still don't guess. No model-name regex, no "is this OpenAI?" sniffing the same base URL serves OpenRouter, Ollama, LM Studio, vLLM ... ... rather defeat the point. Housekeeping Two scripted-socket tests for the retry path, which previously had a proud total of zero: one pins that the second request really goes out carrying the same tools, the other that an endpoint refusing

... look at the numbers, because once you are staring at 9 out of 10 there is always a story available for the missing one. Comment from Omri Ben-Shoham(@omri_ben_shoham1): Good writeup - the distinction between blocking Training vs blocking Agent is the part people are going to get wrong for a while. One thing worth adding from the operating side of an agent, not the site-owner side - when an agent gets blocked, it usually doesn't fail ... ... counter that rotates a scraper's address after three consecutive blocks. A dead product in the catalogue is therefore indistinguishable from hostility, and three dead products in a row make the machine react as though it is being refused

... Here's the blind spot. Netfox checks every device by connecting to it across your network. Perfect for a printer, a NAS, a phone. Wrong for the Mac you're sitting at A dev server on 127.0.0.1:3000 genuinely refuses connections from anywhere else so the check says "closed". Accurate, and completely useless. The most interesting services on the machine you care most about are exactly the ones a network probe can never see. Local Services ... ... network, grouped by category. Local Services is the one place that couldn't work that way: The Ports tab on a network device, grouped by category Also fixed: a closed port now says closed. A port that actively refuses

... Netfox 0.13.0 the endpoint that refuses to be careless Netfox can expose a read-only metrics endpoint, so your own monitoring can scrape your network. Handy and, it turns out, far too easy to leave wide open. Switch on "allow access from other devices" without setting a token and that endpoint was reachable from anywhere on your network with no authentication at all . What it serves is your entire device inventory: every IP, every MAC address, every hostname, every open ... ... port. That's fixed, and it's the kind of fix I'd rather tell you about than quietly bury in a changelog. It fails closed. No token, no network endpoint. Netfox refuses

... here's what we do, here's where we're unreliable, here's the thing we put in front of you before it goes out. That's a harder page to write and a much harder one for a competitor to copy, because it means you actually went and found your failure modes. Curious whether anyone has tried this and what it did to conversion. My guess is it costs you signups and buys you retention. Comment from Yuki_Code1 ... ... lukewarm interview written up as a triumph, because that's the direction the model naturally pulls. So there's a gate: it judges whether there's a real endorsement in the transcript first, and if there isn't, it refuses

Comment from Raj Nagulapalle(@rnagulapalle): honestly the "refuses to guess" part came from getting burned by my own tools. i'd describe a bug, the agent would confidently open the wrong file, and i'd lose an hour before realizing it just guessed. so we made ours read ...

One addition: you cannot separate them by observation, but you can by deliberately violating the constant once. A property that survives a test faking an unattended caller ... ... specific to denial.

... inside your app if they can only feel understood while they're talking to your model you haven't solved loneliness. You've made it more comfortable to stay lonely. You've built a very sophisticated waiting room. The alternative is to design for the exit. Concretely, that means three things. Point users back at real people, not deeper into the app. The most valuable thing an emotional AI can do isn't be a better listener than your friends ... ... help you go have the conversation with your friend that you've been avoiding. Rehearse the hard talk. Untangle what you actually feel before you say it out loud. Then get out of the way. Refuse

... writing better code. After thousands of hours of building, I realized I was wrong. Code doesn't create a product. It gives shape to an idea. The real beginning happens much earlier. It starts with a question that refuses to leave your mind. The kind of question that stays with you while you're working, walking, reading, or trying to sleep. Months pass. Sometimes years. Yet the question keeps growing until building becomes the only way to answer it. Looking ... ... survive long enough to deserve becoming reality. So I'd like to ask every builder here: What was the first question that made you start building your product? Not your business model. Not your first feature. The question that refused
