+## Instruction Priority
+
+Superpowers skills override default system prompt behavior, but **user instructions always take precedence**:
+
+1. **User's explicit instructions** (CLAUDE.md, AGENTS.md, direct requests) — highest priority
+2. **Superpowers skills** — override default system behavior where they conflict
+3. **Default system prompt** — lowest priority
+
+If CLAUDE.md or AGENTS.md says "don't use TDD" and a skill says "always use TDD," follow the user's instructions. The user is in control.
+
 ## How to Access Skills
 
 **In Claude Code:** Use the `Skill` tool. When you invoke a skill, its content is loaded and presented to you—follow it directly. Never use the Read tool on skill files.
 
 **In other environments:** Check your platform's documentation for how skills are loaded.
 
+## Platform Adaptation
+
+Skills use Claude Code tool names. Non-CC platforms: see `references/codex-tools.md` for tool equivalents.
