+# CLI Mode: Plan (/cli:mode:plan)
+
+## Purpose
+
+Execute planning and architecture analysis using CLI tools with specialized template.
+
+**Supported Tools**: codex, gemini (default), qwen
+
+## Execution Flow
+
+1. **Parse tool selection**: Extract `--tool` flag (default: gemini)
+2. **If `--enhance` flag present**: Execute `/enhance-prompt "[topic]"` first
+3. Parse topic (original or enhanced)
+4. Detect target directory (from `--cd` or auto-infer)
+5. Build command for selected tool with planning template
+6. Execute analysis
+7. Save to session (if active)
+
+## Core Rules
+
+1. **Enhance First (if flagged)**: Execute `/enhance-prompt` before planning
+2. **Directory Context**: Use `cd` when `--cd` provided or auto-detected
+3. **Template Required**: Always use planning template
+4. **Session Output**: Save to `.workflow/WFS-[id]/.chat/plan-[timestamp].md`
+
+## Command Template
+
+**Core Guidelines**: @~/.claude/workflows/intelligent-tools-strategy.md
+
+```bash
+cd [directory] && ~/.claude/scripts/gemini-wrapper --all-files -p "
+PURPOSE: [planning goal from topic]
+TASK: Comprehensive planning and architecture analysis
+CONTEXT: @{CLAUDE.md,**/*CLAUDE.md} [entire codebase in directory]
+EXPECTED: Strategic insights, implementation roadmap, key decisions
+RULES: $(cat ~/.claude/prompt-templates/plan.md) | Focus on [topic area]
+"
+```
+
+## Examples
+
+**Basic Planning**:
+```bash
+cd . && ~/.claude/scripts/gemini-wrapper --all-files -p "
+PURPOSE: Design user dashboard feature architecture
+TASK: Comprehensive architecture planning for dashboard
+CONTEXT: @{CLAUDE.md,**/*CLAUDE.md}
+EXPECTED: Architecture design, component structure, implementation roadmap
+RULES: $(cat ~/.claude/prompt-templates/plan.md) | Focus on scalability and UX
+"
+```
+
+**Directory-Specific**:
+```bash
+cd src/auth && ~/.claude/scripts/gemini-wrapper --all-files -p "
+PURPOSE: Plan authentication system redesign
+TASK: Analyze current auth and plan improvements
+CONTEXT: @{CLAUDE.md,**/*CLAUDE.md}
+EXPECTED: Migration strategy, security improvements, timeline
+RULES: $(cat ~/.claude/prompt-templates/plan.md) | Focus on security and backward compatibility
+"
+```
+
+**With Enhancement**:
+```bash
+# User: /gemini:mode:plan --enhance "fix auth issues"
+
+# Step 1: Enhance
+/enhance-prompt "fix auth issues"
+# Returns structured planning context
+
+# Step 2: Plan with enhanced input
+cd . && ~/.claude/scripts/gemini-wrapper --all-files -p "
+PURPOSE: [enhanced goal]
+TASK: [enhanced task description]
+CONTEXT: @{CLAUDE.md,**/*CLAUDE.md} [enhanced context]
+EXPECTED: Strategic plan with enhanced requirements
+RULES: $(cat ~/.claude/prompt-templates/plan.md) | [enhanced constraints]
+"
+```
+
+## Session Output
+
+**Location**: `.workflow/WFS-[topic]/.chat/plan-[timestamp].md`
+
+**Includes**:
+- Planning topic
+- Template used
+- Analysis results
+- Implementation roadmap
+- Key decisions
