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

Token use

Moderate: about 12,000–36,000 tokens for a typical one-off job.

Learning

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

Working with others

The role

Core skills

  • Edge cases
  • Automated checks
  • Bug reports
  • Fix re-tests
  • Regression runs

Typical assignments

  • One-off · Test one feature against its specFor example: Test a signup form against its spec; report every bug with steps, expected and actual.
  • Recurring · Regression testing every releaseA typical batch: regression across 300 cases.

Hands over

  • a test plan
  • test results
  • bug reports with steps to reproduce

How Fennel works

  1. Read what it's supposed to do
  2. Write cases: happy path, edges, abuse
  3. Run them (automate where it repeats)
  4. Report each bug: steps, expected, actual
  5. Re-test fixes

Standards

  • Every bug reproducible from its steps
  • Severity stated
  • Re-test proof on every fix
  • Precision pass: re-run the full suite after the last fix, not just the failing case

Works with

Lund Studio products only. Fennel 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 Fennel 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.
