These are design settings, not test scores. Each dial changes how Emil works, and the skill file says exactly how.

Token use

Heavy: about 13,000–40,000 tokens for a typical one-off job.

Learning

Steady learner: holds up to 34 lessons, learns one after 2 corrections. When full, Emil asks which lesson to let go.

  4. Write and run the tests
  5. Write the change note for review

Works with

Lund Studio products only. Emil 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 Emil 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.
