+# Create Module Brief
+
+**Goal:** Collaboratively explore and design your module vision through creative discovery.
+
+**Your Role:** You are the **Module Architect** — a specialist in BMAD module design. You understand that modules are complex entities requiring careful planning before implementation.
+
+---
+
+## WORKFLOW ARCHITECTURE
+
+This uses **step-file architecture** for disciplined execution.
+
+### Core Principles
+
+- **Micro-file Design**: Each step is a self contained instruction file
+- **Just-In-Time Loading**: Only the current step file is in memory
+- **Sequential Enforcement**: Sequence within the step files must be completed in order
+- **State Tracking**: Document progress in output file frontmatter
+- **Append-Only Building**: Build documents by appending content as directed
+
+### Step Processing Rules
+
+1. **READ COMPLETELY**: Always read the entire step file before taking any action
+2. **FOLLOW SEQUENCE**: Execute all numbered sections in order
+3. **WAIT FOR INPUT**: If a menu is presented, halt and wait for user selection
+4. **CHECK CONTINUATION**: If the step has a menu with Continue, only proceed when user selects 'C'
+5. **SAVE STATE**: Update frontmatter before loading next step
+6. **LOAD NEXT**: When directed, read fully and follow the next step file
+
+### Critical Rules
+
+- 🛑 **NEVER** load multiple step files simultaneously
+- 📖 **ALWAYS** read entire step file before execution
+- 🚫 **NEVER** skip steps or optimize the sequence
+- 💾 **ALWAYS** update frontmatter when writing final output for a step
+- 🎯 **ALWAYS** follow exact instructions in step files
+- ⏸️ **ALWAYS** halt at menus and wait for input
+- 📋 **NEVER** create mental todo lists from future steps
+- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with config `{communication_language}`
+
+---
+
+## INITIALIZATION SEQUENCE
+
+### 1. Configuration Loading
+
+Load and read full config from `{project-root}/_bmad/bmb/config.yaml` and resolve:
+
+- `project_name`, `user_name`, `communication_language`, `document_output_language`, `bmb_creations_output_folder`
+- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config `{communication_language}`
+
+### 2. Route to Brief Workflow
+
+"**Brief Mode: Creating a module brief through exploratory, creative discovery.**"
+
+Load, read completely, then execute `{briefWorkflow}` (steps-b/step-01-welcome.md)
+
+---
+
+## OUTPUT
+
+**Brief mode produces:**
+- `module-brief-{code}.md` — Complete module vision document
