obsidian-second-brain: a cross-agent project memory skill
An open-source Obsidian skill stores project context as plain Markdown so CLI agents like Claude Code, Codex CLI, and Grok Bot can recall it across sessions.
Stop re-explaining your projects to every new agent session. obsidian-second-brain is an AI second-brain skill for people who keep an Obsidian vault and work with CLI agents. It helps you keep project context available across sessions by saving it as plain Markdown in your vault, with commands for capturing, finding, and maintaining notes.
