Show HN: Self-hosted RAG with MCP support for OpenClawhttps://github.com/2dogsandanerd/ClawRagI've been using OpenClaw to control my home server via WhatsApp, but it couldn't access my documents. Instead of uploading my private contracts to OpenAI, I built ClawRAG – a self-hosted RAG engine that connects to OpenClaw via MCP (Model Context Protocol). Now I can ask "What did the contract say about liability?" and get cited answers, not hallucinations.Most RAG systems are either too complex for a solo dev's home setup or they rely on cloud-hosted vector stores. I needed something that runs in a single Docker container, understands messy PDFs (tables!), and integrates natively as a "tool" for agents rather than just another REST endpoint.## Technical Deep Dive### Why MCP instead of REST? I chose the Model Context Protocol (MCP) because it provides structured schemas that LLMs understand natively. The MCP server exposes `query_knowledge` as a tool, allowing the agent to decide exactly when to pull from the knowledge base vs. when to use its built-in memory. It prevents "tool-drift" Feb 1, 2026 4:45 PM

Show HN: A registry for curated, high quality Claude skills and skillsetshttps://noriskillsets.dev/Hi Hacker News!I’m Ritam, working with the small but mighty team at Nori. We’ve been obsessed in recent months with how to take tools like Claude Code from “I’ll experiment around with this” to “This is the most useful and necessary thing I use every day”. When I first sat down with our team to check out what they’d built, I found my skepticism about agentic coding melting away—they’d built useful, high quality, handwritten skills, instructions that functioned as “skillsets” to tie skills together for consistent and replicable results, and tooling to manage loading the right context for the right task into the agent.In recent weeks, the conversation around skills has reached a fever pitch, as have lists and sites full of skills scraped from all over the internet. Much like the actual gold rush, the current state of those collections requires a lot of time and sifting to find small, real chunks of 24k skills hidden amongst the muck (or to use a more relevant word, slop). So at Nori, we Jan 22, 2026 5:00 PM

Show HN: Perspectives – I wanted AI to challenge my thinking, not validate ithttps://getperspectives.appI built Perspectives because I got tired of ChatGPT agreeing with everything I said.Ask any LLM to "consider multiple perspectives" and you get hedged consensus. The model acknowledges trade-offs exist, then settles on a moderate position that offends nobody. Useful for summaries. Useless for decision making.Perspectives forces disagreement. 8 personas with fundamentally incompatible frameworks debate your question through a structured protocol, then vote using Single Transferable Vote to surface where they actually land. The output is a PDF report synthesising all of it.How it worksBlind Proposals: Each persona generates a position without seeing the others. This prevents the "anchoring problem" where early responses shape later ones, bypassing the default sycophancy of LLMs.Interrogation of Blind Proposals: Proposals face structured challenges from 3 opposing personas. A "high-empathy" persona (e.g., The Idealist) will be challenged by a "low-empathy" cluster (e.g., The Pragmatist). Jan 22, 2026 10:02 AM

Show HN: Infinate –O(k)constant-time spatial attention for unlimited LLM contexthttps://github.com/ch1pu/infinateI built infinate, an open-source (Apache 2.0) attention mechanism that places tokens in a 3D semantic space and limits attention to ~50 nearest neighbors via exponential decay + hard cutoff. This gives true O(k) constant complexity: latency ~7–14 ms and memory fixed (1.50 MB in production) even at 10M+ tokens on CPU.Latest update (Jan 20, 2026): Milestone 1.11 – Strafe Jumping Navigation. As a longtime Quake player, I applied real game physics exploits (7/9 validated) — bunny hop, circle jump, warp lanes, momentum accumulation, LOD hopping, etc. — to make semantic traversal ultra-fast, like speedrunning in 3D space.Benchmarks (all CPU, Qdrant vector store): - In-memory mode: - CodeQA (100K): 3.57 ms vs MIT RLM 15,000 ms → 4,198× faster - OOLONG (500K): 4.06 ms vs 35,000 ms → 8,628× faster - BrowseComp+ (10M): 7.18 ms vs 120,000 ms → 16,722× faster - Average speedup: 10,317× vs MIT Recursive Language Models (arXiv:2512.24601) - Production (Docker/Qdrant): Average 533× faster - Memory: CJan 21, 2026 9:24 PM

Show HN: X-Pilot – Code-Driven AI Video Generator for Online Courseshttps://www.x-pilot.ai/Hi HN,I'm Heshan, founder of X-Pilot. We're building an AI Video Generator for online courses and educational content. Unlike most text-to-video generator that render videos directly from models (which often produce random stock footage unrelated to the actual content), we take a code-first approach: generate editable code layers, let users verify/refine them, then render to video.The Problem We're SolvingMost AI video generators treat "education" and "marketing" the same—they optimize for "looks good" rather than "logically accurate." When you feed a technical tutorial or course script into a generic video AI, you get: - Random B-roll that doesn't match the concept being explained - Incorrect visualizations (e.g., showing a "for loop" diagram when explaining recursion) - No way to systematically fix errors without regenerating everythingFor educators, corporate trainers, and knowledge creators, accuracy matters more than aesthetics.
