refactor: update CLI commands and tool agent configurations

- Enhanced CLI command documentation for analyze, chat, and execute
- Updated mode-specific commands (bug-index, code-analysis, plan)
- Added cli-execution-agent for autonomous CLI task handling
- Refined agent configurations for Codex, Gemini, and Qwen

 ## Parameters
 
-- `--tool <codex|gemini|qwen>` - Tool selection (default: gemini)
+- `--agent` - Use cli-execution-agent for automated context discovery (5-phase intelligent mode)
+- `--tool <codex|gemini|qwen>` - Tool selection (default: gemini, ignored in agent mode)
 - `--enhance` - Enhance topic with `/enhance-prompt` first
 - `--cd "path"` - Target directory for focused planning
 - `<topic>` (Required) - Planning topic or architectural question
 
 ## Execution Flow
 
+### Standard Mode (Default)
+
 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)

+### Agent Mode (`--agent` flag)
+
+Delegate planning to `cli-execution-agent` for intelligent strategic planning with automated architecture discovery.
+
+**Agent invocation**:
+```javascript
+Task(
+  subagent_type="cli-execution-agent",
+  description="Create strategic plan with automated architecture discovery",
+  prompt=`
+    Task: ${planning_topic}
+    Mode: plan (strategic planning)
+    Tool Preference: ${tool_flag || 'auto-select'}
+    ${cd_flag ? `Directory Scope: ${cd_path}` : ''}
+    Template: plan
+
+    Agent will autonomously:
+    - Discover project structure and existing architecture
+    - Build planning prompt with plan template
+    - Execute strategic planning analysis
+    - Generate implementation roadmap and save
+  `

+```

+The agent handles all phases internally.

 ## Core Rules
 
 1. **Analysis Only**: This command provides planning recommendations and insights - it does NOT modify code

 ## Examples
 
-**Basic Planning Analysis**:
+**Basic Planning Analysis (Standard Mode)**:
+```bash
+/cli:mode:plan "design user dashboard architecture"
+# Executes: Gemini with planning template
+# Returns: Architecture recommendations, component design, roadmap
+```
+
+**Intelligent Planning (Agent Mode)**:
+```bash
+/cli:mode:plan --agent "design microservices architecture for payment system"
+# Phase 1: Classifies as architectural planning, keywords ['microservices', 'payment', 'architecture']
+# Phase 2: MCP discovers existing services, payment flows, integration patterns
+# Phase 3: Builds planning prompt with plan template + current architecture context
+# Phase 4: Executes Gemini with comprehensive project understanding
+# Phase 5: Saves planning document with implementation roadmap and migration strategy
+# Returns: Strategic architecture plan + implementation roadmap + risk assessment
+```
