Create GitHub Actions Workflow Specification

SkillDev tools

Lets your agent create a formal spec of an existing GitHub Actions workflow for maintenance.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Create GitHub Actions Workflow Specification skill

About this capability

Create a formal specification for an existing GitHub Actions CI/CD workflow, optimized for AI consumption and workflow maintenance.

What this skill tells your AI

The instructions your AI receives, as published by github/awesome-copilot in skills/create-github-action-workflow-specification/SKILL.md and read by ahel’s review.

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 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.
