🎯 Common Use Cases

📚 Creating a Python Library

# src/mylib/core.py
"""Core functionality for mylib."""

def process_data(data: list[dict]) -> list[dict]:
    """Process data with validation.

    Args:
        data: List of dictionaries to process

    Returns:
        Processed data

    Example:
        >>> process_data([{"value": 1}])
        [{"value": 1, "processed": True}]
    """
    return [{"processed": True, **item} for item in data]

# tests/test_core.py
import pytest
from mylib.core import process_data

def test_process_data():
    result = process_data([{"value": 1}])
    assert result[0]["processed"] is True
    assert result[0]["value"] == 1

🖥️ Building a CLI Tool

# src/mylib/cli.py
import click
from .core import process_data

@click.command()
@click.argument('input_file', type=click.Path(exists=True))
@click.option('--output', '-o', help='Output file')
def cli(input_file, output):
    """Process INPUT_FILE and save results."""
    # Load data
    with open(input_file) as f:
        data = json.load(f)

    # Process
    result = process_data(data)

    # Output
    if output:
        with open(output, 'w') as f:
            json.dump(result, f)
        click.echo(f"✓ Saved to {output}")
    else:
        click.echo(json.dumps(result, indent=2))

🔌 Creating a Plugin System

# src/mylib/plugins.py
from typing import Protocol

class ProcessorPlugin(Protocol):
    """Protocol for processor plugins."""

    def process(self, data: dict) -> dict:
        """Process a single item."""
        ...

def load_plugins() -> dict[str, ProcessorPlugin]:
    """Dynamically load all plugins."""
    # Implementation here
    pass

🎯 Project Planning (Recommended First Step)

Why Plan First?

Research shows that projects with documented requirements are 97% more likely to succeed. Poor requirements gathering causes 39% of software project failures. Take 15-30 minutes to plan your project properly—it will save hours of development time.

Generate Your Project Requirements

Before coding, create comprehensive planning documents using Claude Code's interactive planning workflow:

# Launch the interactive planning workflow
# Note: Specify guides/ directory for output to avoid conflicts with pdoc
claude /plan

What this creates:

• Product Requirements Document (PRD) - Clear project vision, user needs, and success criteria
• Technical Specification - Architecture approach, technology decisions, and implementation plan
• User Stories (if applicable) - Detailed scenarios and acceptance criteria
• Development Roadmap - Feature prioritization and implementation phases

Planning Workflow Features

• Research-backed methodology - Based on 2024-2025 software project success factors
• Adaptive questioning - Adjusts based on project type (library, API, CLI tool, web app)
• Comprehensive coverage - Business requirements, technical approach, and implementation planning
• Living documents - Easy to update as requirements evolve
• AI optimization - Provides Claude with complete project context for better assistance

Project Types Supported

• Python Libraries - Package development with clear API design
• CLI Tools - Command-line applications with user workflow planning
• REST APIs - Service development with endpoint specification
• Web Applications - Full-stack projects with user experience planning

Sample Planning Session

$ claude /plan

🎯 Let's plan your project for maximum success!

Phase 1: Project Discovery
What is the name of your project? my-data-processor
In one sentence, what does this project do? Transforms messy CSV data into clean, validated datasets
Who will use this project? Data analysts and Python developers working with CSV files

[Interactive session continues...]

✅ Generated comprehensive planning documents:
   - guides/PRD.md
   - guides/TECHNICAL_SPECIFICATION.md  
   - guides/USER_STORIES.md

> **📁 Important**: Planning documents are saved in `guides/` to avoid conflicts with pdoc-generated API documentation in `docs/`. This also ensures maximum context inclusion for Claude Code.

🚀 Ready to start development with clear requirements!

When to Use Planning

• ✅ Always recommended - 15-30 minutes of planning saves hours of development
• ✅ New projects - Essential for getting started on the right track
• ✅ Complex features - Break down complicated requirements into manageable pieces
• ✅ Team projects - Ensure everyone understands the vision and approach
• ✅ Client work - Professional documentation and clear expectations

📋 Prerequisites

Required Tools:

• Python 3.9+ and Poetry
• Git and GitHub CLI (optional)
• For AWS features: AWS CLI and SAM CLI
• For secret management: chezmoi and age

PyPI Setup (Important - Do This First!):

1. Reserve your package name on PyPI and TestPyPI
2. Set up Trusted Publishing:
   • Publisher: GitHub Actions
   • Repository: your-account/your-repo
   • Workflow: pipeline.yaml
   • Environment: pypi

Windows Users:

# Install tools
winget install Python.Python.3.11
winget install twpayne.chezmoi
winget install --id FiloSottile.age

# Set environment for Claude Code
$env:CLAUDE_CODE_GIT_BASH_PATH="C:\gitbash\bin\bash.exe"

AWS Setup (Optional - One Time Per Account):

# Enable GitHub Actions OIDC
aws iam create-open-id-connect-provider \
  --url https://token.actions.githubusercontent.com \
  --client-id-list sts.amazonaws.com

🏗️ Project Setup

This template uses a two-stage bootstrap process that eliminates common setup friction:

Stage	Purpose	When to Run
Stage 1	Template customization	Immediately after cloning
Stage 2	AWS integration	After sam pipeline bootstrap

Why two stages? This approach prevents dependency conflicts and handles the interactive SAM setup gracefully.

See the Bootstrap Guide for complete setup instructions.

📝 Documentation Best Practices

API Documentation (Google-style docstrings):

def process_data(data: list[str], format: str = "json") -> dict:
    """Process input data and return formatted results.

    Args:
        data: List of strings to process.
        format: Output format ("json" or "xml").

    Returns:
        Processed data in specified format.

    Example:
        >>> process_data(["item1", "item2"])
        {"processed": ["item1", "item2"]}
    """

Library vs CLI Design:

• Use __all__ to control public API surface
• Keep CLI commands in separate modules
• Document both library and CLI usage in module docstrings

🛠️ Development Workflow

Using Make (Recommended)

# Daily development - clean, simple commands
make test          # Run unit tests (excludes slow/CI-only)
make test-all      # Run all tests including slow ones
make lint          # Lint and auto-fix with ruff
make format        # Format code with ruff
make security      # Run security scans
make docs          # Generate documentation
make clean         # Remove all build artifacts

# See all available commands
make help

Using Poetry Directly

# If you prefer direct commands
poetry run pytest              # Run tests
poetry run pytest -m ""        # Run all tests including slow  
poetry run ruff check --fix    # Lint and fix
poetry run ruff format .       # Format code

# Security and compliance
poetry install --with security,compliance
poetry run bandit -r src/
poetry run safety check
poetry run pip-licenses

📊 Telemetry (Optional)

Help improve your library by enabling anonymous usage telemetry:

# Check status
ai-test-script telemetry status

# Enable with consent prompt
ai-test-script telemetry enable

# Test configuration
ai-test-script telemetry test

See Telemetry Documentation for details on privacy guarantees and configuration.

💡 Pro Tips

• Repository Setup: See .github/REPOSITORY_SETUP.md for branch protection, linear history, and Renovate configuration
• Renovate: Auto-merge is configured for safe updates (patch/minor)
• Security Scans: Only run on main/dev branches to keep feature branches fast
• Windows Users: All commands work in Git Bash, PowerShell, and CMD (see troubleshooting guide)
• Claude Code: See the Claude Development Guide for AI-assisted development

🖥️ MCP Server Setup

• Add MCP Servers: Use claude mcp add <server-name> to add servers for GitHub, AWS, and more.
  • GitHub MCP Server Setup:
    1. Ensure CLAUDE_GITHUB_PAT is set as an env var
    2. Run this command:

    claude mcp add-json github "{
      `"command`": `"docker`",
      `"args`": [
        `"run`",
        `"-i`",
        `"--rm`",
        `"-e`",
        `"GITHUB_PERSONAL_ACCESS_TOKEN`",
        `"ghcr.io/github/github-mcp-server`"
      ],
      `"env`": {
        `"GITHUB_PERSONAL_ACCESS_TOKEN`": `"$($env:CLAUDE_GITHUB_PAT)`"
      }
    }"
