Hippo adds biological memory decay, sleep to agents

Most agent memory systems act as naive filing cabinets that grow until context windows break, making Hippo's "forgetting by default" approach a necessary paradigm shift for long-running workflows.

• –Biologically-inspired decay ensures outdated workarounds and stale preferences fade naturally instead of permanently polluting the context window
• –Error memories automatically receive doubled half-lives, ensuring agents remember painful lessons like failed deployments or flaky tests
• –The automated sleep consolidation phase merges redundant episodic entries into stable semantic knowledge without user intervention
• –Cross-tool shared memory breaks vendor lock-in, allowing lessons learned in Cursor to persist seamlessly when switching to Claude Code
• –Zero-dependency SQLite backbone and automatic hook installation for popular agent frameworks makes adoption completely frictionless
