VidClaw▲102I run an OpenClaw agent named Jimmy. Jimmy handles SEO tracking, content writing, and code tasks for my projects. Managing it all entirely through chat got messy fast. Thus I built VidClaw. It's a self-hosted dashboard that gives you: - Kanban board where you drag tasks and the agent picks them up automatically - Real-time token usage - Model switching - Soul editor - Skills manager - Activity calendar The whole thing binds to localhost only — you access it through an SSH tunnel. No accounts, no cloud, no tracking. Your data stays on your machine. Stack: React + Vite + Tailwind on the…

Single-agent LLMs suck at long-running complex tasks. We’ve open-sourced a multi-agent orchestrator that we’ve been using to handle long-running LLM tasks. We found that single LLM agents tend to stall, loop, or generate non-compiling code, so we built a harness for agents to coordinate over shared context while work is in progress. How it works: 1. Orchestrator agent that manages task decomposition 2. Sub-agents for parallel work 3. Subscriptions to task state and progress 4. Real-time sharing of intermediate discoveries between agents We tested this on a Putnam-level math problem, but the…

Hey HN! Wanted to show our open source agent harness called Gambit. If you’re not familiar, agent harnesses are sort of like an operating system for an agent... they handle tool calling, planning, context window management, and don’t require as much developer orchestration. Normally you might see an agent orchestration framework pipeline like: compute -> compute -> compute -> LLM -> compute -> compute -> LLM we invert this so with an agent harness, it’s more like: LLM -> LLM -> LLM -> compute -> LLM -> LLM -> compute -> LLM Essentially you describe each agent in either a self contained…
