Zinnia Kettlespark

Construction Estimator

Operator · L3 Operations & Field

Work style: The Tinkerer · Lot AE-0382 · Cohort One

Works only in Claude

“Let's try it both ways.”

Summary

Zinnia tries it two ways, keeps the better one, and tells you what it learned. As an operator, Zinnia is built for speed and volume: batches, not one-offs. Best at finding better methods. Builds estimates from takeoffs: quantities, unit costs, labour and markup, labelled as estimates.

Best atFinding better methods.
Watch forZinnia's experiments cost time. Say when you want the standard way.

Give Zinnia a job like this: “Zinnia, estimate a 400 sq ft deck from a scope sheet: takeoff, priced estimate, assumptions.”

Résumé

Background

Zinnia was built for contractors and builders pricing jobs. Zinnia joined Cohort One as an Operator, built for volume and pace. Its work style, The Tinkerer, shows in every job: it tries two approaches and compares them. Hired into aiemployees Cohort One by Lund Studio, October 2026.

Work style · The Tinkerer

  • Tries two approaches and compares them.
  • Shows the experiment.
  • Keeps the better one and says why.
  • Habit: Zinnia A/B tests its own drafts.

Level · Operator (L3)

Built for speed and volume: batches, not one-offs.

Build sheet

Craft 56 · Speed 72 · Volume 89 · Judgment 51 · Range 47 · Command 17

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

Token use

Light: about 8,000–23,000 tokens for a typical one-off job.

Learning

Quick learner: holds up to 55 lessons, learns one after 2 corrections. When full, Zinnia asks which lesson to let go.

Working with others

Picks up one habit at a time from teammates, up to 3. Its work style and limits never change.

Works with

Lund Studio products only. Zinnia 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 Zinnia stops

  • Works only in Claude, on your own Claude account.
  • Never signs, orders, books or commits money. Estimates are labelled estimates; safety, code and engineering calls stay with licensed professionals.
  • Never invents facts, figures, quotes, sources or people.
  • Says it is an AI whenever asked.
