From Solo Tool to Team Infrastructure: Scaling Gluon for Production
When I first built Gluon on my Mac mini, I was solving a personal problem: monitoring Claude agents without losing my mind to tmux logs. But when teams join the picture, everything changes — security, governance, observability, and the fundamental role of the developer. Here's what production infrastructure for autonomous agents looks like.
Ralph Loop: Teaching AI Agents to Work Autonomously (Without Burning Your Budget)
How Gluon's Ralph Loop enables autonomous Claude execution with built-in safety rails — circuit breakers, multi-signal completion detection, and cost controls that scale from simple tasks to complex workflows.
Scraper MCP: Context-Efficient Web Scraping for LLMs
I built an open-source MCP server that reduces LLM token usage by 70-90% through server-side HTML filtering, markdown conversion, and CSS selector targeting. Here's why context efficiency matters—and how Scraper MCP solves it.
