Plan Cascade - CLI Guide

Version: 4.3.3 Last Updated: 2026-02-02

This document provides detailed instructions for using the Plan Cascade standalone CLI tool.

Installation

# Install from PyPI
pip install plan-cascade

# Install with LLM support
pip install plan-cascade[llm]

# Install all dependencies
pip install plan-cascade[all]

Quick Start

# Configuration wizard (first-time use)
plan-cascade config --setup

# Simple mode - one-click execution
plan-cascade run "Implement user login functionality"

# Expert mode - more control
plan-cascade run "Implement user login functionality" --expert

# Interactive chat mode
plan-cascade chat

# Auto-run with parallel execution (NEW)
plan-cascade auto-run --parallel

# Mega-plan for large projects (NEW)
plan-cascade mega plan "Build e-commerce platform"

Dual-Mode Design

Simple Mode (Default)

Designed for new users and quick tasks, AI automatically determines strategy and executes.

plan-cascade run "Add an exit button"
# -> AI determines: Small task -> Direct execution

plan-cascade run "Implement user login functionality"
# -> AI determines: Medium feature -> Generate PRD -> Auto-execute

plan-cascade run "Build e-commerce platform: users, products, orders"
# -> AI determines: Large project -> Mega Plan -> Multi-PRD cascade

Expert Mode

Designed for experienced users, provides fine-grained control.

plan-cascade run "Implement user login" --expert

Expert mode supports:

View and edit PRD
Select execution strategy
Specify Agent for each Story
Adjust dependencies
Configure quality gates

Global Options

The following options are available for all commands:

--legacy-mode            Use legacy path mode (store files in project root instead of user directory)
--project <path>         Project path (default: current directory)
--verbose                Enable verbose output

Legacy Mode: By default, Plan Cascade stores planning files in a platform-specific user directory (~/.plan-cascade/<project-id>/ on Unix or %APPDATA%/plan-cascade/<project-id>/ on Windows). Use --legacy-mode to store files in the project root directory instead (compatible with older versions).

AI Automatic Strategy Determination

In simple mode, AI automatically selects the best execution strategy based on requirements:

Input	AI Determination	Execution Strategy
"Add an exit button"	Small task	Direct execution (no PRD)
"Implement user login functionality"	Medium feature	Hybrid Auto (auto-generate PRD)
"Develop a blog system with users, articles, comments"	Large project	Mega Plan (multi-PRD cascade)
"Refactor payment module without affecting existing functionality"	Requires isolation	Hybrid Worktree

Determination Dimensions:

Task Scale: Single task / Multiple features / Complete project
Complexity: Whether decomposition into multiple Stories is needed
Risk Level: Whether isolated development is needed
Dependencies: Whether there are cross-module dependencies

Troubleshooting

API Key Not Configured

Error: Claude API key is required

Solution:

plan-cascade config --setup
# Or set environment variable
export ANTHROPIC_API_KEY=sk-ant-...

Backend Unavailable

Error: Backend 'ollama' not available

Solution: Ensure Ollama is started and running on the correct port.

Model Not Supported

Error: Model 'gpt-5' not found

Solution: Check if the model name is correct, use --model to specify a valid model.
