🧩 Citadel: Operating Layer for AI Coding Tools

Citadel has an interesting positioning, describing itself as the operating layer for Claude Code and OpenAI Codex. In short, it provides underlying infrastructure support for these AI coding tools. It focuses on multi-agent orchestration and context management, handling persistent project memory, intent routing, safety hooks, and cost telemetry. When developers start running parallel agent fleets in a project, a unified routing and observability layer like this becomes quite practical.
