hackmd-cli team-notes update --teamPath=<path> --noteId=<id> --content='...'
hackmd-cli team-notes delete --teamPath=<path> --noteId=<id>

Change Tracking

Use hackmd-track.js (in scripts/) to detect document changes efficiently.

Track a Note

node scripts/hackmd-track.js add <noteId>

Check for Changes

# Single note - outputs content only if changed
node scripts/hackmd-track.js changes <noteId>

# All tracked notes
node scripts/hackmd-track.js changes --all

# JSON output for parsing
node scripts/hackmd-track.js changes <noteId> --json

Manage Tracking

node scripts/hackmd-track.js list              # Show tracked notes
node scripts/hackmd-track.js remove <noteId>   # Stop tracking
node scripts/hackmd-track.js reset <noteId>    # Reset (next check shows as changed)

How It Works

1. hackmd-track.js add stores note's lastChangedAt timestamp
2. hackmd-track.js changes compares current lastChangedAt with stored value
3. If changed: outputs content and updates stored timestamp
4. If unchanged: outputs nothing (use --verbose for status)

State stored in ./.hackmd/tracked-notes.json (current working directory)

Note Metadata Fields

When using --output json, notes include:

Field	Description
lastChangedAt	Unix timestamp of last modification
lastChangeUser	{name, userPath, photo} of last editor
titleUpdatedAt	When title changed
tagsUpdatedAt	When tags changed
