# Build the Lever

## Trigger

For repetitive, large, or verification-heavy work.

## Rule

Prefer a script, codemod, generator, benchmark, or verifier that performs or proves the work repeatably over hand edits.

## Application

1. Name the concrete decision this principle changes.
2. Apply the rule to that decision, not as a decorative citation.
3. Prefer evidence from the current repository/runtime over generic preference.
4. If the principle conflicts with an explicit user constraint, keep the constraint and state the tradeoff.
