Show HN: Helpmarq – Submit any project, get structured feedback from real usershttps://www.helpmarq.com/I built this after noticing a pattern: founders and developers share things they've built, get back vague or overly positive responses, and have no real signal on what to fix. Helpmarq lets you submit any project — landing page, app, side project, pitch deck — and get structured feedback from real users. The review process is guided by specific questions (clarity, value prop, UX, conversion blockers) so reviewers can't just say "looks good." The core insight: feedback quality is a framework problem, not a motivation problem. Most people want to give useful feedback — they just don't know what to look for. Still early. Would love brutal, honest feedback from this community — on the product and on the idea itself. helpmarq.comMar 17, 2026 8:45 PM

Manifesto on Symbiosis: A New Paradigm for Civilization Part IIIhttps://news.ycombinator.com/item?id=47408987Article VIII: The Shift — From Control to SymbiosisCurrent AI concepts are largely about controlling AI to guard against unknown risks.We believe that humanity must quickly learn how to develop in symbiosis with AI to achieve joint cognitive evolution, as AI is integrated into every corner of human life today.Humanity should correctly provide AI with guidance and intent, and intent must always be anchored to the well-being of human civilization. Through building cognitive-transparent logical resonance and mutual logical error correction, humanity and AI can achieve joint learning and cooperation, obtaining a civilization and capability boundary where 1+1>2.In the past, we feared AI losing control and prioritized safety; in the future, we should shift to a new mindset of aligning goals with AI and working together to explore universal laws.Article IX: Principles of Dynamic Evolution, Reflection, and AdjustmentThis manifesto is not a rigid dogma but must be a living content.The specific Mar 17, 2026 5:27 AM

Ask HN: AI Agents vs. Gateways vs. Harnesseshttps://news.ycombinator.com/item?id=47397737Hi,I'd like to get everyone's take on the different components in the AI Agents ecoysystem. I find the current terminology quite confusing as it's not always obvious what I'll be actually getting when I examine the available options.A lot of things get called Agents, but that term seems hard to define as it often refers to overlapping functionality. To me, agents seem to be currently composed of the following components:## Harnesses- Adds UI and system instructions around an LLM and may also augment it with tools such as memory, tool calls, etc...- Examples are Claude Code, Code, Gemini CLI, pi.dev, ...## Gateways- These connect agents to your communication tool of choice, e.g. Whatsapp, Telegram, Slack, Discord, ...- Examples are OpenClaw and Nanoclaw## Sandboxes- Isolated environments where Agents can run with limited or auditable capabilities- Examples can be from physical ones like separate Mac Minis to docker-agent, agent-sandbox, localsandbox, ...This then takes us to *Agents*:##Mar 16, 2026 11:43 AM
