Aigent OS

Aigent OS is an open-source alternative to context compaction that runs sessions with persistent memory.

Aigent OS is an open-source tool designed for long-running AI sessions. When context reaches an 80 percent threshold, it prompts the agent to save a checkpoint file, executes a clear command, and resumes work in a fresh session with persistent markdown memory stored in git. It includes skill routing, memory guardrails, and specialist sub-agents. The software runs locally on your machine with no dedicated server. It requires Node.js, bash, and Claude Code to operate.
