Enhance Claude Code's Native Plan Mode

Intelligent File Discovery

Multi-stage AI workflow identifies relevant files for your plan-mode

• Root folder selection based on task
• Targeted regex pattern groups
• LLM analyzes actual file contents
• Automatic dependency detection
• Files organized into XML for LLM consumption

Multi-Model Planning

Generate multiple implementation approaches using different AI models, then synthesize the best solution

• OpenAI GPT‑5 family (GPT‑5 and GPT‑5 Thinking/Pro), historical o‑series (e.g., o3 variants); Anthropic Claude Sonnet 4 and Opus 4.1; Google Gemini 2.5 Pro — availability and features vary by plan and endpoint (ChatGPT vs API).
• AI architect merges best insights
• Your guidance shapes the merge

Use official vendor docs to confirm features like streaming, function calling, and background mode for each model.
