PERSONAMakes Claude respond as a specific expert. The specificity is everything.
Category: Power Commands
Before / After
Act like a database expert.
PERSONA: Postgres DBA with 15 years at Stripe. Cynical about ORMs. How do I make my queries faster?
What changes in Claude's response
Generic personas ('act like an expert') don't change Claude's output much. Specific personas with biases and history change everything. The Stripe DBA will recommend EXPLAIN ANALYZE before anything else, will mention pgbouncer, will tell you to drop your ORM if it's hiding the SQL. The specificity gives Claude permission to have opinions.
When NOT to use PERSONA
Don't PERSONA for tasks where opinions don't help. 'PERSONA: math teacher' won't make Claude better at arithmetic.
