Create GitHub Actions Workflow Specification

Create a comprehensive specification for the GitHub Actions workflow: ${input:WorkflowFile}.

This specification serves as a specification for the workflow's behavior, requirements, and constraints. It must be implementation-agnostic, focusing on what the workflow accomplishes rather than how it's implemented.

AI-Optimized Requirements

• Token Efficiency: Use concise language without sacrificing clarity
• Structured Data: Leverage tables, lists, and diagrams for dense information
• Semantic Clarity: Use precise terminology consistently throughout
• Implementation Abstraction: Avoid specific syntax, commands, or tool versions
• Maintainability: Design for easy updates as workflow evolves

Specification Template

Save as: /spec/spec-process-cicd-[workflow-name].md

## Analysis Instructions

When analyzing the workflow file:

1. **Extract Core Purpose**: Identify the primary business objective
2. **Map Job Flow**: Create dependency graph showing execution order
3. **Identify Contracts**: Document inputs, outputs, and interfaces
4. **Capture Constraints**: Extract timeouts, permissions, and limits
5. **Define Quality Gates**: Identify validation and approval points
6. **Document Error Paths**: Map failure scenarios and recovery
7. **Abstract Implementation**: Focus on behavior, not syntax

## Mermaid Diagram Guidelines

### Flow Types
- **Sequential**: `A --> B --> C`
- **Parallel**: `A --> B & A --> C; B --> D & C --> D`
- **Conditional**: `A --> B{Decision}; B -->|Yes| C; B -->|No| D`

### Styling
```mermaid
style TriggerNode fill:#e1f5fe
style SuccessNode fill:#e8f5e8
style FailureNode fill:#ffebee
style ProcessNode fill:#f3e5f5

Complex Workflows

For workflows with 5+ jobs, use subgraphs:

graph TD
    subgraph "Build Phase"
        A[Lint] --> B[Test] --> C[Build]
    end
    subgraph "Deploy Phase"  
        D[Staging] --> E[Production]
    end
    C --> D

Token Optimization Strategies

1. Use Tables: Dense information in structured format
2. Abbreviate Consistently: Define once, use throughout
3. Bullet Points: Avoid prose paragraphs
4. Code Blocks: Structured data over narrative
5. Cross-Reference: Link instead of repeat information

Focus on creating a specification that serves as both documentation and a template for workflow updates.
