About MemoryCustodian

What the tool does and who it's for

MemoryCustodian is an open-source, local-first tool that provides repo-native durable project memory for coding agents such as Codex, Claude Code, and Gemini. Instead of using hosted services or injecting massive instructions that bloat prompt context, MemoryCustodian stores decisions, architectural constraints, rejected approaches, and project context as plain Markdown files in your repository. These files can be version-controlled, code-reviewed, and updated via normal Git workflows. A manifest system dynamically routes and loads only the specific context required for each task.

Key capabilities

Repo-native storage: Project memory lives as plain Markdown files in your Git repository.
Selective manifest loading: Context is loaded dynamically based on task relevance to avoid prompt bloat.
Cross-agent compatibility: Integrates seamlessly with OpenAI Codex, Claude Code, Gemini, and generic agent workflows.
Local-first & open source: Operates entirely locally without requiring a hosted external memory service.
Versioned & reviewable: Memory files are tracked, diffed, reviewed, and deleted like standard code.
Structured memory components: Built-in schemas for brief.md, decisions.md, constraints.md, and do-not-use.md.
CLI initialization & management: Easily setup and manage memory structures across projects with command-line tools.
