# CLI Mode: Bug Index (/cli:mode:bug-index)

## Purpose

Execute systematic bug analysis and fix suggestions using CLI tools with diagnostic 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 "[bug-description]"` first
3. Parse bug description (original or enhanced)
4. Detect target directory (from `--cd` or auto-infer)
5. Build command for selected tool with bug-fix template
6. Execute analysis
7. Save to session (if active)

## Core Rules

1. **Enhance First (if flagged)**: Execute `/enhance-prompt` before analysis
2. **Directory Context**: Use `cd` when `--cd` provided or auto-detected
3. **Template Required**: Always use bug-fix template
4. **Session Output**: Save to `.workflow/WFS-[id]/.chat/bug-index-[timestamp].md`

## Command Template

**Core Guidelines**: @~/.claude/workflows/intelligent-tools-strategy.md

```bash
cd [directory] && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: [bug analysis goal]
TASK: Systematic bug analysis and fix recommendations
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md} [entire codebase in directory]
EXPECTED: Root cause analysis, code path tracing, targeted fixes
RULES: $(cat ~/.claude/prompt-templates/bug-fix.md) | Bug: [description]
"
```

## Examples

**Basic Bug Analysis**:
```bash
cd . && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: Debug authentication null pointer error
TASK: Identify root cause and provide fix
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md}
EXPECTED: Root cause, code path, minimal fix, impact assessment
RULES: $(cat ~/.claude/prompt-templates/bug-fix.md) | Bug: null pointer in login flow
"
```

**Directory-Specific**:
```bash
cd src/auth && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: Fix token validation failure
TASK: Analyze token validation bug in auth module
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md}
EXPECTED: Validation logic analysis, fix recommendation
RULES: $(cat ~/.claude/prompt-templates/bug-fix.md) | Bug: token validation fails intermittently
"
```

**With Enhancement**:
```bash
# User: /gemini:mode:bug-index --enhance "login broken"

# Step 1: Enhance
/enhance-prompt "login broken"
# Returns:
# INTENT: Debug login authentication failure
# CONTEXT: Known session state issue
# ACTION: Check session management → verify token → test flow

# Step 2: Analyze with enhanced context
cd . && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: Debug login authentication failure
TASK: Analyze session management, token handling, auth flow
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md} Known: session state issue
EXPECTED: Root cause in session/token, targeted fix
RULES: $(cat ~/.claude/prompt-templates/bug-fix.md) | Focus on session management
"
```

## Analysis Focus

**Template provides**:
- **Root Cause Analysis**: Systematic investigation
- **Code Path Tracing**: Execution flow analysis
- **Targeted Solutions**: Minimal, specific fixes
- **Impact Assessment**: Side effect evaluation

## Session Output

**Location**: `.workflow/WFS-[topic]/.chat/bug-index-[timestamp].md`

**Includes**:
- Bug description
- Template used
- Analysis results
- Recommended actions
