What it does

Obsidian-second-brain provides a persistent memory for CLI agents, storing project information and decisions in plain markdown for easy recall and reuse.

When to use it

•When working on complex projects that require frequent explanations of context and decisions
•When using multiple CLI agents and need a unified memory system
•When seeking to automate knowledge management and research tasks

Ready-to-paste prompt

Use the `sb init` command to set up a new second-brain system, and then use `sb note 'My Project'` to create a new note with a template for storing project context and decisions

Heads up: Make sure you have Python and the required dependencies installed, and that your Obsidian vault is properly configured to work with the second-brain system, as outlined in the README
