Operating layer for Claude Code and Codex with persistent memory and parallel agent fleets

Pluginfreeglobal

Citadel is an open-source operating layer for Claude Code and OpenAI Codex that preserves project state between sessions, routes requests, coordinates parallel agent work, applies safety hooks, and tracks cost telemetry. It's built for developers who want coding agents to work reliably across real repositories instead of starting fresh each time.
