Phase 1 — Slack (2–3 hours) - You create the GrowthCode OS Slack workspace + install Make.com app: ~20 min your time - I wire Jarvis morning briefing → #jarvis: ~45 min - I wire Marketing Agent → #marketing on each run: ~30 min - I set up #commands so you can trigger agents from Slack: ~45 min Phase 2 — Gmail Read + Draft Reply (2–3 hours) - Make.com already has your Google connection, so no new auth needed - Gmail watcher scenario: ~1 hour - Claude reads + drafts reply logic: ~45 min - Slack alert to #jarvis with summary: ~30 min Phase 3 — Jarvis Brain / Memory (2–3 hours) - Make.com Data Store design + setup: ~45 min - Update Voice Trigger to write session context to memory: ~45 min - Update jarvis-gc.netlify.app system prompt to pull live context: ~1 hour Total active build time: 6–9 hours In calendar terms — if we start now and work straight through, it's a solid full day. More realistically 2 days with testing, your approval checkpoints, and any debugging. The critical path item is Slack — you need to create the workspace and connect Make.com before I can build anything else. That's about 20 minutes on your end. Want to knock that out now so I can start Phase 1 while you do it?
