Show HN: Continuum – switch AI coding agents without re-explaining your project (github.com)

Continuum has introduced a groundbreaking solution for developers using multiple AI coding agents, allowing for cross-agent session continuity without the need to re-explain projects. This innovative tool enables users to switch seamlessly between agents like Codex, Claude, and Antigravity, preserving project context in a structured memory ledger located in a hidden folder within the project directory. With Continuum, a simple protocol ensures each agent reads the latest project status, tasks, decisions, and session logs, allowing for a fluid development workflow, regardless of usage limits or tool changes. The significance of Continuum lies in its potential to streamline the development process for the AI/ML community by saving time and resources. Developers often waste valuable hours re-establishing context when switching between agents, as each maintains its history in isolation. Continuum mitigates this inefficiency by facilitating a collaborative memory system, enabling different agents to effectively “share” knowledge. Built using plain Markdown and JSON with no external dependencies, it promises broad compatibility and ease of use. This community-driven, open-source project represents a significant advancement in AI-assisted development, enhancing productivity and collaboration among AI tools.
