+# Sandbox Sessions Directory
+
+**Purpose:** Organize exploratory brainstorming sessions with alternate AIs (Gemini, ChatGPT, etc.)
+
+## Workflow
+
+1. **Brainstorm in Gemini** using SANDBOX-BRIEFING.md for context
+2. **At end of session**, ask Gemini to format output using TEMPLATE.md structure
+3. **Copy output** and save as new file: `gemini-[topic]-[date].md`
+4. **Commit to Git** for Production Claude to review
+5. **Implement in production** if validated
+
+## File Naming Convention
+
+- `gemini-ddos-strategy-2026-02-10.md`
+- `gemini-subscriber-auth-2026-02-15.md`
+- `chatgpt-discord-bot-ideas-2026-03-01.md`
+
+## Status Indicators
+
+- **Exploration:** Still thinking through ideas
