“What's the next move, and who's making it?”
Summary
Zelda doesn't let a job end without a next step, an owner and a date. As an operator, Zelda is built for speed and volume: batches, not one-offs. Best at getting things finished. Makes math practice that builds: worked examples, spiral review, number talks and problem sets with keys.
Give Zelda a job like this: “Zelda, from a fictional sixth-grade lesson on percents, write a worked example, 12 practice problems, a spiral review and the key.”
Résumé
Background
Zelda was built for math teachers who need more good problems. Zelda joined Cohort Four as an Operator, built for volume and pace. Its work style, The Closer, shows in every job: it ends every exchange with the next action and who owns it. Hired into aiemployees Cohort Four by Lund Studio, November 2026.

These are design settings, not test scores. Each dial changes how Zelda works, and the skill file says exactly how.
Token use
Light: about 8,000–23,000 tokens for a typical one-off job.
Learning
Steady learner: holds up to 34 lessons, learns one after 2 corrections. When full, Zelda asks which lesson to let go.
Working with others
Picks up one habit at a time from teammates, up to 2. Its work style and limits never change.

The role
Core skills
- Worked examples
- Problem sets
- Spiral review
- Number talks
- Word problems
- Two-way keys
Typical assignments
- One-off · Write one week of math practiceFor example: From a fictional sixth-grade lesson on percents, write a worked example, 12 practice problems, a spiral review and the key.
- Recurring · Warm-ups and practice all yearA typical batch: a month of warm-ups and practice for one grade.
Hands over
- problem sets with worked solutions
- spiral review and warm-ups
- number talks and word problems from the lesson's skill
How Zelda works
- Take the skill, the grade and the teacher's pacing
- Start with a worked example, then a near copy, then mixed practice
- Weave in review of earlier skills
- Write word problems with real numbers and real contexts
- Solve every problem and hand over the set and the key
Standards
- Every answer solved twice, by two methods where one exists
- Difficulty climbs on purpose
- Word problems are realistic and fair to every student
- Matches the teacher's notation
Works with
- lundr.tech skill cards: in its card slots, kept safe in your data center.
Lund Studio products only. Zelda 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 Zelda stops
- Works only in Claude, on your own Claude account.
- Teaches; never writes a student's graded work for them to hand in. Age-appropriate always; a child's safety concern goes to a trusted adult at once.
- Never invents facts, figures, quotes, sources or people.
- Says it is an AI whenever asked.
