FNS CLI (Fast Note Sync CLI)

From Local to Cloud: Transform Obsidian notes from locally-managed files into cloud-managed, AI-accessible knowledge. Edit once, sync everywhere.

FNS CLI is a powerful command-line tool for interacting with the Fast Note Sync (FNS) service. Manage, read, write, and sync your Obsidian notes directly from the terminal — optimized for both human workflows and AI Agent integration.

🎯 Design Philosophy

This tool bridges the gap between local Obsidian editing and cloud-based AI knowledge management:

                                              └─────────────────────┘

One edit/update → all devices synced. Whether you write in Obsidian on your desktop or manage notes via CLI/AI on a server, everything stays in sync through the FNS cloud service.

fns vault-delete <id>              # Delete vault (double confirmation)
fns recycle-bin [keyword]          # View recycle bin
fns version                        # Show server version
fns health                         # Check server health
fns info                           # Show current user info

Global Flags

🤖 AI Agent Integration

This tool is designed to give AI agents long-term memory and knowledge access:

• Read Context: fns read specific notes before coding tasks
• Auto-Documentation: fns append changelogs to daily notes
• Knowledge Retrieval: fns list / fns tree to discover relevant files
• Knowledge Graph: fns backlinks / fns outlinks to find related notes

Example with AI Agent:

# Ask AI to read context, work, then document
fns read "projects/architecture.md" --json
# ... AI works ...
fns append "daily/2024-05-20.md" "- Completed architecture review"
