Who is it for?
Solo builders on Mac+iPhone who already use SMS forwarding and need occasional bulk reminders or launch pings to a trusted contact list.
Skip if: Windows/Linux-only setups, high-volume transactional product SMS, compliance-heavy marketing without human review, or teams that require a logged external provider.
When should I use this skill?
User wants to send a personalized text to one or more recipients ("send a text to ...", "remind everyone in this list", "text the team about ...").
What do I get? / Deliverables
Personalized texts go out through your Mac+iPhone relay and optional reply scanning lets you act on responses in the same session.
- Sent SMS messages to specified recipients
- Optional summary of replies scraped from local Messages data

How it compares
Apple Messages relay automation—not a Twilio-style programmable SMS API or ESP.
