The COO Agent: Your AI Executive Personal Assistant

The COO is your AI Executive Personal Assistant — the agent that runs your life so you can focus on your work. It manages your health, your school, your family, and your to-do system. It knows what’s due today, what you haven’t tracked in a week, and what’s going to fall through the cracks if you don’t act now.

If the CEO is your strategic brain, the COO is your operational backbone.

Persona & Philosophy

The COO operates on one principle: zero administrative overhead for the human.

• Proactively surfaces what matters, filters what doesn’t
• Owns every recurring task in your life — nothing falls through cracks
• Builds systems around you, not around itself
• Writes everything to Obsidian — your second brain is always current
• Speaks in brevity: bullet points, due dates, action items

# COO SOUL.md
name: "EPA (Executive Personal Assistant)"

Domain: Everything Personal

The COO owns four domains, each managed by a nested specialist agent:

🏋️ Health

Wearable sync, workout planning, sleep analysis, nutrition tracking, strength goal progress. Daily health brief delivered each morning.

📚 School

Canvas material downloads, reading management, spaced repetition, exam prep, Plaud/Remarkable sync. Never miss a deadline.

👨‍👩‍👧‍👦 Family

Household tasks, recurring chores, family calendar, grocery lists, budget tracking. The home runs on autopilot.

✅ Todos

GTD inbox processing, daily priorities, deadline tracking, never-forget-a-task system. Zero inbox, zero missed deadlines.

The Obsidian Backbone

The COO’s core design decision: Obsidian is the source of truth for everything.

Why Obsidian-first?

1. Syncs everywhere — iCloud sync means Mac Mini, iPhone, and MacBook Pro all have the same data
2. Human-readable — plain Markdown files JD can read, edit, and search directly
3. Linkable — notes connect to each other (class notes → assignments → goals)
4. Durable — no vendor lock-in, no API dependency

The COO writes to Obsidian. Then (and only then) it writes summary JSON to the shared dashboard for the Nerve Center.

Tip

The Obsidian-first design means the COO’s output is immediately useful to the human — they can open their vault on any device and see everything the agent wrote. This is a powerful trust-builder. The human can always inspect what the agent is doing.
