# CLI Mode: Code Analysis (/cli:mode:code-analysis)

## Purpose

Systematic code analysis with execution path tracing template (`~/.claude/prompt-templates/code-analysis.md`).

**Supported Tools**: codex, gemini (default), qwen
**Key Feature**: `--cd` flag for directory-scoped analysis

## Parameters

- `--tool <codex|gemini|qwen>` - Tool selection (default: gemini)
- `--enhance` - Enhance analysis target with `/enhance-prompt` first
- `--cd "path"` - Target directory for focused analysis
- `<analysis-target>` (Required) - Code analysis target or question

## Execution Flow

1. **Parse tool selection**: Extract `--tool` flag (default: gemini)
2. **If `--enhance` flag present**: Execute `/enhance-prompt "[analysis-target]"` first
3. Parse analysis target (original or enhanced)
4. Detect target directory (from `--cd` or auto-infer)
5. Build command for selected tool with code-analysis template
6. Execute deep analysis (read-only, no code modification)
7. Save to `.workflow/WFS-[id]/.chat/code-analysis-[timestamp].md`

## Core Rules

1. **Analysis Only**: This command analyzes code and provides insights - it does NOT modify code
2. **Tool Selection**: Use `--tool` value or default to gemini
3. **Enhance First (if flagged)**: Execute `/enhance-prompt` before analysis
4. **Directory Context**: Use `cd` when `--cd` provided or auto-detected
5. **Template Required**: Always use code-analysis template
6. **Session Output**: Save analysis results to session chat

## Analysis Capabilities (via Template)

- **Systematic Code Analysis**: Break down complex code into manageable parts
- **Execution Path Tracing**: Track variable states and call stacks
- **Control & Data Flow**: Understand code logic and data transformations
- **Call Flow Visualization**: Diagram function calling sequences
- **Logical Reasoning**: Explain "why" behind code behavior
- **Debugging Insights**: Identify potential bugs or inefficiencies

## Command Template

```bash
cd [directory] && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: [analysis goal]
TASK: Systematic code analysis and execution path tracing
MODE: analysis
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md} [entire codebase in directory]
EXPECTED: Execution trace, call flow diagram, debugging insights
RULES: $(cat ~/.claude/prompt-templates/code-analysis.md) | Focus on [aspect]
"
```

## Examples

**Basic Code Analysis**:
```bash
cd . && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: Trace authentication execution flow
TASK: Analyze complete auth flow from request to response
MODE: analysis
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md}
EXPECTED: Step-by-step execution trace with call diagram, variable states
RULES: $(cat ~/.claude/prompt-templates/code-analysis.md) | Focus on control flow
"
```

**Directory-Specific Analysis**:
```bash
cd src/auth && ~/.claude/scripts/gemini-wrapper --all-files -p "
PURPOSE: Understand JWT token validation logic
TASK: Trace JWT validation from middleware to service layer
MODE: analysis
CONTEXT: @{CLAUDE.md,**/*CLAUDE.md}
EXPECTED: Validation flow diagram, token lifecycle analysis
RULES: $(cat ~/.claude/prompt-templates/code-analysis.md) | Focus on security
"
```

## Code Tracing Workflow

```bash
# 1. Find entry points and related files
rg "function.*authenticate|class.*AuthService" --files-with-matches
mcp__code-index__search_code_advanced(pattern="authenticate|login", file_pattern="*.ts")

# 2. Build call graph understanding
# entry → middleware → service → repository

# 3. Execute deep analysis (analysis only, no code changes)
/cli:mode:code-analysis --cd "src" "trace execution from entry point"
```

## Output Routing

**Output Destination Logic**:
- **Active session exists AND analysis is session-relevant**:
  - Save to `.workflow/WFS-[id]/.chat/code-analysis-[timestamp].md`
- **No active session OR standalone analysis**:
  - Save to `.workflow/.scratchpad/code-analysis-[description]-[timestamp].md`

**Examples**:
- During active session `WFS-auth-refactor`, analyzing auth flow → `.chat/code-analysis-20250105-143022.md`
- No session, tracing request lifecycle → `.scratchpad/code-analysis-request-flow-20250105-143045.md`
