Claude Code Agents Pipeline

A TDD-focused workflow automation tool that generates test files and implementation templates across 4 languages (JavaScript, Python, Go, Bash).

Overview

The Claude Code Agents Pipeline automates the TDD (Test-Driven Development) workflow by:

• Converting requirements into structured formats (Gherkin, JIRA)
• Generating test files and implementation scaffolding
• Providing production-ready code templates with validation, error handling, and testing infrastructure
• Managing git workflow (branching, commits, PRs)
• Maintaining pipeline state for resume capability

Note: This tool generates code templates with production-ready infrastructure (validation, error handling, testing). The generated code provides a solid foundation but requires domain-specific customization for your business logic.

Quick Start

# Install via npm (global)
npm install -g @claude/pipeline

# Or install via Homebrew
brew tap anthropics/claude
brew install claude-pipeline

# Initialize and run workflow
claude-pipeline requirements 'Build authentication system'
claude-pipeline gherkin
claude-pipeline stories
claude-pipeline work PROJ-2
claude-pipeline complete PROJ-2

Pipeline Stages

requirements → gherkin → stories → work → complete

1. Requirements

Converts a description into structured requirements with functional and non-functional considerations.

./pipeline.sh requirements "Build user authentication"
# Creates: .pipeline/requirements.md

2. Gherkin

Generates BDD (Behavior-Driven Development) scenarios from requirements.

./pipeline.sh gherkin
# Creates: .pipeline/features/*.feature

3. Stories

Creates JIRA hierarchy (Epic + Stories) from Gherkin features.

./pipeline.sh stories
# Creates: .pipeline/exports/jira_import.csv
#          .pipeline/exports/jira_hierarchy.json

4. Work

Generates test files and implementation templates for a story.

./pipeline.sh work PROJ-2
# Creates: tests/proj_2_test.sh (or .js, .py, .go)
#          proj_2.sh (or .js, .py, .go)

What gets generated:

• ✅ Test file with basic test structure
• ✅ Implementation file with:
  • Input validation framework
  • Error handling structure
  • Generic business logic template
  • Batch processing capabilities
• ✅ Syntax validation for the target language

What you need to customize:

• Domain-specific business logic
• Specific validation rules for your use case
• Integration with your data sources
• Feature-specific processing logic

5. Complete

Reviews code, runs tests, merges to main, and closes JIRA story.

./pipeline.sh complete PROJ-2

What This Tool Provides

✅ Production-Ready Infrastructure

• Input validation patterns
• Structured error handling
• Logging framework
• Test scaffolding
• Git workflow automation
• State management
• JIRA integration

⚠️ Requires Customization

• Business Logic: Generic templates need domain-specific implementation
• Validation Rules: Customize for your specific requirements
• Integration: Connect to your data sources and APIs
• Feature Logic: Add the specific functionality your story requires

Example: What Gets Generated

Input

./pipeline.sh requirements "Build a calculator"
./pipeline.sh work CALC-1

Generated Implementation (Bash example)

#!/bin/bash
# Implementation for CALC-1

validate() {
    local data="$1"
    # Generic validation - CUSTOMIZE for calculator logic
    if [ -z "$data" ]; then return 1; fi
    if [ ${#data} -gt 1000 ]; then return 1; fi
    return 0
}

implement() {
    local input="$1"
    if ! validate "$input"; then
        echo '{"success":false,"error":"Invalid input"}'
        return 1
    fi

    # Generic processing - REPLACE with calculator operations
    processed=$(echo "$input" | tr '[:upper:]' '[:lower:]')
    echo "{\"success\":true,\"data\":\"$processed\"}"
    return 0
}

# Entry point
main() {
    implement "$@"
}

main "$@"

Generated Test

#!/bin/bash
# Test for CALC-1

test_implementation_exists() {
    if [ -f "./calc_1.sh" ]; then
        echo "PASS: Implementation exists"
        return 0
    fi
    echo "FAIL: Implementation not found"
    return 1
}

test_basic_functionality() {
    result=$(./calc_1.sh "test input")
    if echo "$result" | grep -q "success"; then
        echo "PASS: Basic functionality works"
        return 0
    fi
    echo "FAIL: Basic functionality failed"
    return 1
}

# Run tests
test_implementation_exists
test_basic_functionality

./pipeline.sh cleanup                     # Remove .pipeline directory

Options

-v, --verbose    # Enable verbose output
-d, --debug      # Enable debug mode
-n, --dry-run    # Preview without executing
-V, --version    # Show version
-h, --help       # Show help

State Management

Pipeline maintains state in .pipeline/state.json:

{
  "stage": "work",
  "currentStory": "PROJ-2",
  "epicId": "PROJ-1",
  "stories": {},
  "branch": "feature/PROJ-2",
  "version": "1.0.0"
}

State features:

• ✅ Automatic backup before changes
• ✅ Corruption detection and recovery
• ✅ Concurrent access protection (locking)
• ✅ Version compatibility checking
• ✅ State history tracking

Known Limitations

Code Generation

• Generic Templates: Generated code is template-based, not domain-specific
• Requires Customization: Business logic must be implemented by developer
• No AI Analysis: Does not analyze requirements to generate specific logic
• Scaffolding Tool: Provides structure, not implementation

JIRA Integration

• Optional: Works without JIRA (generates CSV for import)
• acli Required: Uses Atlassian CLI if installed
• Mock Mode: Creates placeholder data when acli unavailable

Git Integration

• Remote Required: git push requires configured remote origin
• Manual Merge: PR creation and merging handled outside tool
• Local First: Works in local repos, push/PR features optional
