+# Copilot instructions
+
+## Context
+
+PHP library in the tiny-blocks ecosystem.
+
+## Mandatory pre-task step
+
+Before starting any task, read and strictly follow `.claude/CLAUDE.md` and every rule file in
+`.claude/rules/`. These files are the absolute source of truth for code generation. Apply every
+rule strictly. Do not deviate from the patterns, folder structure, or naming conventions defined
+in them.
