cligen - CLI Tool Generator

Fast CLI tool scaffolding generator for Bash & Python

Overview

Generate production-ready CLI tool skeletons with proper argument parsing, help docs, error handling, and shell completions — in seconds.

Usage

For the AI Agent

When the user asks to "create a CLI tool" or "generate a command-line tool":

1. Run cligen create with the appropriate parameters
2. If the user specifies requirements, translate them into --commands
3. Validate the generated tool with cligen validate
4. Report results to the user

CLI Commands

# Generate a new CLI tool (Bash)
cligen create --name mytool --lang bash --commands "status,deploy,config" --desc "My deployment tool"

# Generate a new CLI tool (Python)
cligen create --name mytool --lang python --commands "build,test" --desc "Build tool"

# Validate an existing CLI tool
cligen validate ./mytool/

# Generate shell completions
cligen completions --shell bash --commands "build,test,deploy"

# Check development environment
cligen doctor

Options

What Gets Generated

• Main script — executable entry point with full arg parsing & dispatch
• README.md — usage documentation
• .gitignore — language-appropriate ignores
• requirements.txt — (Python only) dependency file

Best Practice Checks

The validate command checks 10 criteria:

1. Executable main script
2. Valid shebang
3. Strict mode (Bash: set -euo pipefail)
4. Error handling
5. Argument parsing
6. Help documentation
7. Version information
8. README.md
9. .gitignore
10. Copyright header
