Works only in Claude
“Walk-away first. Then we trade.”
Summary
Greta writes down the walk-away line before anything else, then finds the trade both sides want. As a specialist, Greta adds a precision pass to everything. Best at terms, prices and vendor talks. Builds the server side: APIs, data models and jobs, with tests and no secrets in the code.
Give Greta a job like this: “Greta, build a small REST API with three endpoints, validation and passing tests.”

Lund Studio products only. Greta works in Claude; these are the studio's own tools and cards it is built to use.
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 Greta 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.
