COS Starter — AI Chief of Staff

The Problem

AI is electricity. But most people are still running steam-powered factories.

They open a chat window. Type a prompt. Get a generic answer. Close the tab. Repeat tomorrow with zero memory of yesterday.

That's not a workflow. That's a slot machine.

The executives who are actually getting leverage from AI aren't writing better prompts. They're building better context. They're giving the model the same information a world-class chief of staff would have on day 90 of the job:

Who reports to you and how each person operates
What you're working on this quarter and why it matters
Which meetings need prep and which are noise
What patterns keep showing up that you keep missing

This repo gives you the scaffolding to build that.

Quick Start

Prerequisites: Claude Code CLI installed. Claude Max or Team subscription.

1

Create your COS directory

mkdir my-cos && cd my-cos && git init

2

Copy the setup prompt

curl -O https://raw.githubusercontent.com/ukaoma/cos-starter/main/cos-starter.md

3

Run the interactive setup

claude

Then tell Claude: "Read cos-starter.md and run the interactive setup."

5 minutes to a working COS.

Every Claude Code session in this directory starts with your full context loaded. No re-explaining. Just: here's what matters today.

The 4 Tiers

COS isn't a one-time setup. It's a system that deepens over time.

Tier 1 — 5 minutes

Foundation

Run the setup. Get your CLAUDE.md with role, team, and priorities. Consistent, role-aware responses. No more re-explaining your job.

Tier 2 — 30 minutes

Operational

Add people profiles. Configure your first skill. Connect one integration. A morning routine that surfaces what matters.

Tier 3 — 2 weeks

Compounding

Use /learn to capture corrections. Build task tracking. Add meeting notes. The system starts connecting dots you didn't ask about.

Tier 4 — 1+ month

Agentic

Scheduled tasks run automatically. Semantic search across all your meetings. A system that works while you sleep.

Most people never get past Tier 1 with AI tools. COS is designed to pull you forward.

Coverage Gap Assessment

Not sure where to focus? Run /assess to score yourself across 14 COS domains.

Domain	What It Covers
Meeting Intelligence	Capture, classify, extract insights, search by meaning
Task Orchestration	Extract from conversations, dedup, stage, track, complete
Email & Comms Triage	Prioritize inbox, draft responses, follow-up tracking
Calendar Awareness	Meeting prep, conflict detection, time blocking
People Intelligence	Profiles, communication styles, relationship health
Cross-Source Synthesis	Connect signals across meetings + email + tasks + Slack
Strategic Alignment	Goal tracking, resource allocation, priority scoring
Proactive Alerting	Early warnings, signal detection, anomaly flagging
Institutional Memory	Session persistence, correction compounding, decision history
Delegation & Follow-up	Track who owes what, escalation cadence
Content & Research	Market intel, competitor tracking, document creation
Reporting & Dashboards	Status updates, briefings, visual dashboards
Knowledge Management	File organization, templates, SOPs, documentation
Ambient I/O	Multi-surface delivery — terminal, mobile, voice

See assess/coverage-gap-framework.md for the full scoring methodology. Your lowest scores are your highest-leverage next steps.

Integrations

COS connects to your existing tools through MCP servers.

Integration	What It Enables	Setup
Slack	Channel monitoring, message context	10 min
Google Workspace	Email, calendar, docs access	15 min
Meeting Tools	Transcript sync (Granola, Fireflies, Fathom)	10 min
Vector Store	Semantic search across all content	30 min

See integrations/README.md for configuration templates.

For Teams

Running COS for yourself is powerful. Running it across a leadership team is transformative. Multi-role deployments with shared knowledge architecture, cross-role intelligence, and consistent correction propagation.

Philosophy

COS is built on a specific belief: context compounds.

Every correction you make, every meeting you feed in, every person you profile — it all accumulates into a system that understands your work better than any prompt could describe.

The interactive philosophy diagram maps the four tiers:

Foundation — Identity is the starting point
Operational — Routines create rhythm
Compounding — Corrections accumulate into intelligence
Agentic — The system acts without being asked
