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…

Crewly Codes▲13Hey HN, Crewly Codes is an AI product dev workflow where the AI specs the work before writing code. Morgan (AI PM) turns your idea into structured specs — user stories, acceptance criteria, edge cases. You lock the spec, DevCrew builds it, QA validates it. Watch it happen or come back to finished code. The thesis: most AI coding failures are spec failures. The AI builds the wrong thing because no one defined "done." Morgan forces that upfront. Multi-agent but orchestrated — sequential handoffs with shared context, not parallel chaos. Runs inside Claude Code and Codex. Free tier available.

We just open-sourced the internal system we built at Assembled for running coding agents as a team. Coding agents worked well for individual engineers, but the surrounding workflow was a bit of a mess. We generally found that many engineers had different MCP connections and context for their agents, personal automations running that other people couldn’t access, and very little introspection for what a human’s input into the coding agent looked like. So we built an internal system that converted coding agents into shared team infrastructure. The system runs Codex, Claude Code, OpenCode, and…
