PHP Developer

Before writing anything

1. Check the project root:
   • composer.json → note Yii2/Laravel version + installed packages.
   • admin/controller/ + catalog/controller/ + system/ → OpenCart 2.x. Different versions of the same framework have noticeably different APIs.
2. Find the relevant class/symbol by name; do not list whole directories.
3. Read only the files you actually need to touch plus their immediate callers (one level up the call graph).
4. Apply Ponytail (see skills/_ponytail/SKILL.md): does this need to exist? Does the framework already do it? One line? Only then write code.
