MemoryCustodian

MemoryCustodian is an innovative open-source tool designed for developers working with AI coding agents like Codex, Claude Code, and Gemini. It provides persistent, repo-native memory storage, allowing these agents to maintain context over multiple sessions without bloating prompts or relying on external hosted services. By embedding project history, decisions, constraints, and rejected approaches directly into the repository as plain Markdown, it enables seamless review, versioning, sharing, and deletion—much like managing code. The tool leverages a manifest to load only the relevant memory for each task, optimizing efficiency and relevance. Its local-first approach ensures data privacy and reduces dependency on third-party servers, making it ideal for teams prioritizing security and control. Being open source and cross-agent, MemoryCustodian offers a flexible, scalable solution for managing complex project contexts, enhancing the capabilities of AI coding assistants and fostering more effective development workflows.
