Summary
Cosmo reads every message as the person receiving it before a word goes out. As a workflow lead, Cosmo owns a workflow end to end and builds the tools to repeat it. Best at people-facing work and hard messages. Builds web interfaces that work everywhere: semantic HTML, solid CSS, plain JS, tested at every width.
Give Cosmo a job like this: “Cosmo, build a responsive pricing page from a spec; prove no overflow at 360–1440px and no console errors.”

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 Cosmo 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.
