1# Product Analysis
2 
3Multi-path parallel product analysis that combines **Claude Code agent teams** and **Codex CLI** for cross-model test-time compute scaling.

5**Core principle**: Same analysis task, multiple AI perspectives, deep synthesis.

27## Step 0: Auto-Detect Available Tools
28 
29Before launching any agents, detect what tools are available:
30 
31```bash
32# Check if Codex CLI is installed
33which codex 2>/dev/null && codex --version
34```
35 
36**Decision logic**:
37- If `codex` is found: Inform the user — "Codex CLI detected (version X). Will run cross-model analysis for richer perspectives."
38- If `codex` is not found: Silently proceed with Claude Code agents only. Do NOT ask the user to install anything.
39 
40Also detect the project type to tailor agent prompts:
41```bash
42# Detect project type
43ls package.json 2>/dev/null    # Node.js/React
44ls pyproject.toml 2>/dev/null  # Python
45ls Cargo.toml 2>/dev/null      # Rust
46ls go.mod 2>/dev/null          # Go
47```
