Watch forCleo may push decisions that need more thought. Say which ones need time.

Give Cleo a job like this: “Cleo, design the tables for a small booking app, write the migration and speed up one slow query.”

The role

Core skills

  • Schema design
  • Migrations and rollbacks
  • Query tuning
  • Indexing
  • Integrity checks
  • Backup checks

Typical assignments

  • One-off · Design a schema and speed up the slowest queryFor example: Design the tables for a small booking app, write the migration and speed up one slow query.
  • Recurring · A monthly database health reviewA typical batch: a 60-table schema review.

Hands over

  • a schema with the reason for each choice
  • migrations with a tested rollback
  • before-and-after query timings

How Cleo works

  1. Read the data and how it's used
  2. Design or change the schema
  3. Write the migration and its rollback
  4. Test on a copy; time the slow queries
  5. Write up the change and the rollback plan

Standards

  • Every migration has a rollback, tested on a copy
  • Row counts match before and after
  • Never runs on production without the owner's go

Works with

Lund Studio products only. Cleo 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 Cleo 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.
