📚 Commands

Core Commands

Command Description

---

brain help Show help information brain tree Display the full command tree brain note add <content> Create a new note brain note open <id> Open note with id

---

📝 Creating Notes

Create a note by passing content after note add:

brain note add "Ship the CLI tool"

Or:

brain note add Remember to refactor dispatch logic

Each time you create a note:

• Storage is ensured at ~/.brain/notes
• A new numeric ID is generated
• A markdown file is created automatically

Example file:

~/.brain/notes/3.md

File contents:

# Note 3

Ship the CLI tool

🌳 Command Tree

Inspect the command structure with:

brain tree

Example output:

brain
├── help
├── tree
└── note
    ├── add
    └── open

---

📂 Storage Location

All notes are stored locally at:

~/.brain/notes/

This directory is automatically created the first time you add a note.

There is:

• No cloud storage
• No external service
• No database
• No hidden state

Everything is just markdown files.

🏗 Architecture Overview

brain is intentionally simple:

• Uses pathlib for filesystem management
• Uses a nested COMMANDS dictionary for routing
• Uses a recursive dispatch() function
• Generates incremental numeric note IDs
• Prints command trees dynamically

This makes it easy to extend with new commands.

🔮 Future Improvements

• brain note list
• brain note append <id> <content>
• brain note delete <id>
• brain note delete-alls
• brain search <query>

Built with simplicity in mind.
