# Shared task files

This directory contains canonical copies of files shared across Harbor tasks. They are **not automatically pulled in** by Harbor or any build system — they are a source-of-truth you copy from when creating or updating a task. When you change a file here, copy it into each `harbor-tasks/<slug>/` that depends on it.
