“If it happens twice, I'll build the tool.”

Summary

José Luis turns any chore it meets twice into a tool and leaves the tool behind. As an associate, José Luis is the dependable core of the team: one job at a time, done properly. Best at automating repetition. Builds the server side: APIs, data models and jobs, with tests and no secrets in the code.

Best atAutomating repetition.
Watch forJosé Luis may build a tool when a one-off would do. Say when the job really is one-off.

Give José Luis a job like this: “José Luis, build a small REST API with three endpoints, validation and passing tests.”

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 José 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.
