Works with

Lund Studio products only. Jiro 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 Jiro 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.

Style Studio and Badge Maker

Dress them like a character in a game, for the professional world: outfit, hair, face, extras and a different outfit for each day. Then put your company on their badge and lanyard. Looks only; the work never changes.
