Workflow Composer

Workflow Composer

⚡ UNIQUE FEATURE: First skill that lets you chain multiple Claude Code skills together into automated workflows with conditional logic, parallel execution, and error handling. Create complex automation pipelines with simple YAML configs.

What This Skill Does

Orchestrates multiple skills into powerful automated workflows:

• Chain skills together: Output of one skill becomes input to the next
• Parallel execution: Run multiple skills simultaneously
• Conditional logic: IF/THEN/ELSE based on skill results
• Error handling: Retry logic and fallback strategies
• Progress tracking: Real-time status of workflow execution
• Workflow templates: Save and reuse common workflows
• Schedule workflows: Run workflows on triggers or schedules

Why This Is Revolutionary

This is the first skill-composition framework for Claude Code:

• No coding required: Define workflows in simple YAML
• Visual workflow builder: Generate workflow configs interactively
• Reusable components: Build once, use everywhere
• Enterprise-ready: Error handling, logging, notifications
• Community workflows: Share workflows with others

Instructions

Creating a Workflow

When a user wants to create a workflow:

1. Interactive Workflow Builder:

   Ask user:
   - What's the goal of this workflow?
   - Which skills should be included?
   - Should any skills run in parallel?
   - What are the inputs needed?
   - What conditions/logic are needed?
   

2. Generate Workflow YAML:

   • Create well-structured YAML file
   • Add comments explaining each step
   • Include error handling
   • Validate syntax

3. Save Workflow:

   • Use Write to create .claude-workflows/workflow-name.yml
   • Add to workflow registry
   • Create documentation

Running a Workflow

When a user wants to run a workflow:

1. Load Workflow:

   Use Read to load workflow YAML from .claude-workflows/
   

2. Validate Inputs:

   • Check all required inputs provided
   • Validate input types
   • Set defaults for optional inputs

3. Create Execution Plan:

   - Parse workflow steps
   - Identify parallel vs sequential
   - Build dependency graph
   - Prepare Task agents
   

4. Execute Workflow:

   For each step:
     - Check 'when' condition (skip if false)
     - If parallel block:
       - Launch all Task agents simultaneously
       - Wait for all to complete
     - If sequential:
       - Execute skill via Task agent
       - Capture output
       - Pass to next step
     - Handle errors:
       - Retry if configured
       - Run on_failure steps
       - Stop or continue based on config
   

5. Track Progress:

   • Use TodoWrite to show workflow progress
   • Update status for each step
   • Show current step and completion percentage

6. Generate Report:

   # Workflow Execution Report
   
   **Workflow**: ${workflow.name}
   **Started**: ${start_time}
   **Duration**: ${duration}
   **Status**: ✅ Success / ⚠️ Partial / ❌ Failed
   
   ## Steps
   1. ✅ generate-readme (2.3s)
   2. ✅ generate-tests (5.1s)
   3. ⏭️ fix-issues (skipped - no issues found)
   4. ✅ deploy (12.4s)
   
   ## Outputs
   - readme_path: /project/README.md
   - test_coverage: 87%
   - deployment_url: https://app.example.com

Best Practices

1. Start simple: Begin with 2-3 steps, then expand
2. Add error handling: Always plan for failures
3. Use parallel execution: Speed up independent tasks
4. Document inputs: Clear descriptions for all parameters
5. Test incrementally: Run each step individually first
6. Version your workflows: Track changes over time

Limitations

• Maximum 20 steps per workflow (performance)
• Parallel execution limited to 5 concurrent skills
• Workflow execution timeout: 30 minutes
• Cannot nest workflows (yet - coming in v2.0)
