  2. 02Record inputs, outputs, and interfaces
  3. 03Identify constraints and quality gates
  4. 04Describe failure paths and recovery
  5. 05Produce diagrams and structured specifications

Use cases

  1. 01Specifying an existing workflow
  2. 02Mapping job dependencies and execution order
  3. 03Recording secrets, variables, and triggers

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.
