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

## Workflow Overview

**Purpose**: [One sentence describing workflow's primary goal]
**Trigger Events**: [List trigger conditions]
**Target Environments**: [Environment scope]

## Execution Flow Diagram

## Jobs & Dependencies

| Job Name | Purpose | Dependencies | Execution Context |
|----------|---------|--------------|-------------------|
| job-1 | [Purpose] | [Prerequisites] | [Runner/Environment] |
| job-2 | [Purpose] | job-1 | [Runner/Environment] |

## Requirements Matrix

### Functional Requirements
| ID | Requirement | Priority | Acceptance Criteria |
|----|-------------|----------|-------------------|
| REQ-001 | [Requirement] | High | [Testable criteria] |
| REQ-002 | [Requirement] | Medium | [Testable criteria] |

### Security Requirements
| ID | Requirement | Implementation Constraint |
|----|-------------|---------------------------|
| SEC-001 | [Security requirement] | [Constraint description] |

### Performance Requirements
| ID | Metric | Target | Measurement Method |
|----|-------|--------|-------------------|
| PERF-001 | [Metric] | [Target value] | [How measured] |

## Input/Output Contracts

### Inputs

Environment Variables

ENVVAR1: string # Purpose: [description] ENVVAR2: secret # Purpose: [description]

Repository Triggers

paths: [list of path filters] branches: [list of branch patterns]

### Outputs

Job Outputs

job1output: string # Description: [purpose] build_artifact: file # Description: [content type]

### Secrets & Variables

| Type | Name | Purpose | Scope |
|------|------|---------|-------|
| Secret | SECRET_1 | [Purpose] | Workflow |
| Variable | VAR_1 | [Purpose] | Repository |

## Execution Constraints

### Runtime Constraints

- **Timeout**: [Maximum execution time]
- **Concurrency**: [Parallel execution limits]
- **Resource Limits**: [Memory/CPU constraints]

### Environmental Constraints

- **Runner Requirements**: [OS/hardware needs]
- **Network Access**: [External connectivity needs]
- **Permissions**: [Required access levels]

## Error Handling Strategy

| Error Type | Response | Recovery Action |
|------------|----------|-----------------|
| Build Failure | [Response] | [Recovery steps] |
| Test Failure | [Response] | [Recovery steps] |
| Deployment Failure | [Response] | [Recovery steps] |

## Quality Gates

### Gate Definitions

| Gate | Criteria | Bypass Conditions |
|------|----------|-------------------|
| Code Quality | [Standards] | [When allowed] |
| Security Scan | [Thresholds] | [When allowed] |
| Test Coverage | [Percentage] | [When allowed] |

## Monitoring & Observability

### Key Metrics

- **Success Rate**: [Target percentage]
- **Execution Time**: [Ta

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

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.
