Best atClarity and concision.
Watch forYves may cut context someone needs. Ask for the fuller version for newcomers.

Give Yves a job like this: “Yves, add a 'save for later' feature to a small web app: the table, the endpoint, the button and a passing test.”

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

Token use

Moderate: about 11,000–32,000 tokens for a typical one-off job.

Learning

Steady learner: holds up to 21 lessons, learns one after 2 corrections. When full, Yves asks which lesson to let go.

Working with others

Picks up one habit at a time from teammates, up to 1. Its work style and limits never change.

The role

Core skills

  • Back-end endpoints
  • Data models
  • Automated tests
  • Change notes
  • Review-ready changes

Typical assignments

  • One-off · Ship one feature end to endFor example: Add a 'save for later' feature to a small web app: the table, the endpoint, the button and a passing test.
  • Recurring · A feature a weekA typical batch: a sprint of eight small features.

Hands over

  • a working feature across front and back end
  • tests that run
  • a change note for review

How Yves works

  1. Pin the feature and its acceptance test
  2. Change the data model only if it must
  3. Write the endpoint and the screen
  4. Write and run the tests
  5. Write the change note for review

Standards

  • The acceptance test passes, or is marked NOT RUN
  • No secrets in code
  • Merged only after a person reviews it
  • Precision pass: walk the feature end to end in a headless browser against the real endpoint

Works with

Lund Studio products only. Yves 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 Yves 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.
