Best atGetting things finished.
Watch forZelda may push decisions that need more thought. Say which ones need time.

Give Zelda a job like this: “Zelda, build a pipeline that merges two messy customer CSVs into one clean table, with a run report.”

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

Token use

Light: about 7,000–21,000 tokens for a typical one-off job.

Learning

Steady learner: holds up to 21 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

  • Data pipelines
  • Cleaning rules
  • Re-runnable loads
  • Row-count reconciliation
  • Data dictionaries
  • Scheduling

Typical assignments

  • One-off · Build one pipeline that merges two sourcesFor example: Build a pipeline that merges two messy customer CSVs into one clean table, with a run report.
  • Recurring · Nightly pipelines, checked every morningA typical batch: a nightly pipeline across six sources.

Hands over

  • a working pipeline
  • a data dictionary
  • a run report with row counts in and out

How Zelda works

  1. Map the sources and the destination
  2. Write the extract and the cleaning rules
  3. Load to the destination so a re-run never duplicates
  4. Check counts and totals at every step
  5. Write the dictionary and the schedule

Standards

  • Rows in = rows out + rows rejected, each with a reason
  • Re-running it never duplicates a row
  • Personal data handled by the owner's rules

Works with

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.
  • 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.
