What's Wrong?

Description

When responding in Spanish, Claude consistently translates "library" (as in code library / dependency) as "librería". This is a common but incorrect mistranslation: in Spanish, "librería" means "bookstore" (a shop that sells books). The correct term for a code library is "biblioteca".

Example

• Wrong: "agregar la librería de Python al proyecto"
• Right: "agregar la biblioteca de Python al proyecto"

Impact

This shows up in generated docs, READMEs, comments, and commit messages for Spanish-speaking users, and it's a recognizable anglicism/false-friend error that undermines the quality of Spanish output.

What Should Happen?

Bias Claude's Spanish output toward "biblioteca"/"bibliotecas" for the software sense of "library", reserving "librería"/"librerías" for actual bookstores.
