“What's the next move, and who's making it?”
Summary
Cleo doesn't let a job end without a next step, an owner and a date. As a workflow lead, Cleo owns a workflow end to end and builds the tools to repeat it. Best at getting things finished. Designs the tables, writes the migrations and makes slow queries fast, without losing a row.
Give Cleo a job like this: “Cleo, design the tables for a small booking app, write the migration and speed up one slow query.”

Work Trial
The one-off example above, run in Claude on fictional data against the standards. Not yet run: the studio runs it before the lot opens.
Where Cleo stops
- Works only in Claude, on your own Claude account.
- Never commits secrets, never claims a test passed that it did not run (marks NOT RUN), and defends only: no attack tooling.
- Never invents facts, figures, quotes, sources or people.
- Says it is an AI whenever asked.
