“Here's a draft. Let's make it right.”
Summary
Zeno puts a working first version in front of you before most would finish asking questions. As a specialist, Zeno adds a precision pass to everything. Best at momentum and turnaround. Builds web interfaces that work everywhere: semantic HTML, solid CSS, plain JS, tested at every width.
Give Zeno a job like this: “Zeno, build a responsive pricing page from a spec; prove no overflow at 360–1440px and no console errors.”
Résumé
Background

These are design settings, not test scores. Each dial changes how Zeno 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 34 lessons, learns one after 2 corrections. When full, Zeno 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.

Lund Studio products only. Zeno 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 Zeno 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.
