My fresh OpenClaw install kept failing. The model wasn’t the problem.

I hit a failure pattern recently that’s way more common than people admit: install OpenClaw connect it to Ollama pull a decent local model test the model directly and it works run the first real agent turn and everything falls apart At that point, most people do the obvious thing: blame the model. Swap Qwen for Llama. Try a bigger model. Try a smaller model. Re-pull weights. Tweak quantization. Repeat. I think that’s usually the wrong first move. The real issue is often prompt baggage, context budgeting, or backend compatibility. Not the model itself. A direct Ollama prompt is a tiny test. An OpenClaw agent turn is not. The tell: direct Ollama works, OpenClaw fails I was reading a thread on r/openclaw where someone on Ubuntu Server said even a brand-new session with just hello could trigger the recurring error. The strange part was that the same model felt “lightning fast and great” when used directly through Ollama with a 4096 context. That’s the giveaway. If this works: curl http://localhost:11434/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "model": "qwen2.5-coder:14b", "messages": [ {"role": "user", "content": "hello"} ] }' but OpenClaw falls over on a normal turn, the model is probably not your first problem. You’re usually dealing with one of these: context blowout oversized system instructions too many skills loaded memory payloads getting injected every turn tool schema overhead output reservation settings that are too aggressive OpenAI-compat quirks in the backend That pattern shows up outside OpenClaw too. I’ve seen the same thing in n8n, Make, Zapier, and custom OpenAI-compatible agent stacks: the hello-world prompt passes, then the real automation fails because the production request is much heavier than anyone realized. A “fresh” OpenClaw install is not actually empty This is the part people miss. By the time your local model sees a real OpenClaw turn, it may already be carrying: system instructions tool definitions skill prompts me

Introducing DevPub - Open Source Dev.to CLI Tool

Recently I went looking for a CLI tool to manage my Dev.to articles from the terminal. I write 4-5 articles per month, track analytics obsessively, and wanted a git-backed workflow. I found 9 existing tools. Tried them all. Here's what happened: devto-cli (Node): Last commit 2 years ago. Broke on install. dev-to-git (Node): Only syncs TO local. Can't push back. slinkity : Abandoned. forem-cli : 3 endpoints implemented out of 40+. Every single tool does the same thing: publish an article. That's it. Maybe pull. Maybe validate tags. Meanwhile the Dev.to API has 40+ endpoints including analytics, semantic search, ML-powered content concepts, follower engagement, trend tracking, and reading list management. Nobody uses them. So I built devpub . Table of Contents What devpub does What I discovered in the API The build story Architecture Try it Contributing What devpub does (that nothing else does) # The basics (every tool does this) devpub push -f articles/my-post.md devpub pull # Analytics in your terminal devpub stats # Views: 246.5K | Reactions: 4.4K | Comments: 402 | Followers: 18.9K # Full dashboard with top articles devpub dashboard # AI-powered search (semantic, not keyword) devpub search "building serverless apps" --semantic # What's trending RIGHT NOW devpub trends # Catch problems before publishing devpub validate The difference isn't one feature. It's coverage. Here's the comparison: Capability devpub Everyone else Publish/update articles Yes Yes Pull articles to local Yes Some Analytics (7 endpoints) Yes No Semantic search Yes No Trend discovery Yes No Article validation Yes No Rate limiting (30 req/30s) Yes No Retry logic for failures Yes No Concepts API (ML topics) Yes No What I discovered in the Dev.to API While building devpub, I found several API endpoints that aren't documented anywhere obvious: 1. Semantic Search -- Dev.to has a full embedding-based search system using Gemini embeddings (768-dimensional vectors) with pgvector. You can search articles b

Introducing Fitz LiveViews: real-time UI in one language, zero JS build

TL;DR — Fitz LiveViews is a real-time UI framework for Fitz , a compiled, gradually-typed language where HTTP, WebSockets, auth, and an ORM are part of the syntax. You write single-file components ( .fitzv ) with state / event / <template> , and the server renders HTML, diffs it, and patches the browser over a WebSocket — no JavaScript build step, no client framework . The same .fitzv can also compile to WebAssembly for offline, zero-round-trip widgets. There's a live component gallery, a course, and a full flagship app (an admin panel with auth + Postgres + Docker) already built with it. Repo : github.com/Thegreekman76/fitz-liveviews · Docs : thegreekman76.github.io/fitz-liveviews This is the first post in the FitzLiveViews series. I'll start with the pitch and the setup; the following posts build things. The problem Building a modern web UI usually means two languages, two type systems, and a build pipeline: a backend (Python / Node / Go) plus a frontend framework (React / Vue / Svelte) plus its toolchain (Vite / Webpack / Babel). You duplicate your types across the wire, you keep two mental models in sync, and node_modules grows a personality of its own. Phoenix LiveView (Elixir) showed there's another way: render on the server, push diffs over a WebSocket, and let the browser stay dumb. No client framework, no API to hand-write, no JSON serialization dance. Fitz LiveViews brings that model to Fitz — and adds a twist: the same component can also compile to WebAssembly when you want purely client-side, offline interactivity. What Fitz LiveViews looks like A component is a single .fitzv file — state, event handlers, and a template, like Vue or Svelte: component Counter { state { count : Int = 0 } event increment () { count = count + 1 } event decrement () { count = count - 1 } event reset () { count = 0 } < template > < div id = " counter-app " > < p > Count : { count } < /p > < button @ click = " increment " >+ 1 < /button > < button @ click = " decrement " >- 1 <

Presentando Fitz LiveViews: UI en tiempo real en un solo lenguaje, sin build de JS

TL;DR — Fitz LiveViews es un framework de UI en tiempo real para Fitz , un lenguaje compilado y de tipado gradual donde HTTP, WebSockets, auth y un ORM son parte de la sintaxis. Escribís componentes de un solo archivo ( .fitzv ) con state / event / <template> , y el servidor renderiza HTML, lo diffea y parchea el browser por WebSocket — sin paso de build de JavaScript, sin framework de cliente . El mismo .fitzv puede además compilar a WebAssembly para widgets offline sin round-trip. Ya hay una galería de componentes en vivo, un curso, y una app flagship completa (un panel de administración con auth + Postgres + Docker) construida con esto. Repo : github.com/Thegreekman76/fitz-liveviews · Docs : thegreekman76.github.io/fitz-liveviews Este es el primer post de la serie FitzLiveViews . Arranco con el pitch y el setup; los siguientes construyen cosas. El problema Armar una UI web moderna normalmente implica dos lenguajes, dos sistemas de tipos, y un pipeline de build: un backend (Python / Node / Go) más un framework de frontend (React / Vue / Svelte) más su toolchain (Vite / Webpack / Babel). Duplicás tus tipos de un lado al otro del cable, mantenés dos modelos mentales en sync, y node_modules desarrolla personalidad propia. Phoenix LiveView (Elixir) mostró que hay otra forma: renderizar en el servidor, empujar diffs por WebSocket, y dejar que el browser quede tonto. Sin framework de cliente, sin API que escribir a mano, sin la danza de serializar JSON. Fitz LiveViews trae ese modelo a Fitz — y suma una vuelta de tuerca: el mismo componente puede además compilar a WebAssembly cuando querés interactividad puramente client-side y offline. Cómo se ve Fitz LiveViews Un componente es un solo archivo .fitzv — state, event handlers y template, como Vue o Svelte: component Counter { state { count : Int = 0 } event increment () { count = count + 1 } event decrement () { count = count - 1 } event reset () { count = 0 } < template > < div id = " counter-app " > < p > Count : { cou
