Extensions are external plugins that add new commands to the CLI. They
are standalone executables named ‘shelly-*’ that can be installed from
git repositories or created locally.
By default, only shows extensions installed in the user plugins directory.
Use –all to show all discovered extensions including those in PATH.
Output is formatted as a table by default. Use -o json or -o yaml for
structured output suitable for scripting.
# List installed extensions
shelly extension list
# List all discovered extensions
shelly extension list --all
# Output as JSON
shelly extension list -o json
# Get extension names only
shelly extension list -o json | jq -r '.[].name'
# Find extensions without versions
shelly extension list -o json | jq '.[] | select(.version == "")'
# Short form
shelly ext ls
