SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Developers and operators often struggle to turn vague infrastructure ideas into formal, actionable change plans. This skill captures an idea or upgrade from interactive IaC artifacts and turns it into a structured INFRA_CHANGE specification that guides planning, cost analysis, and execution.

Core Features & Use Cases

  • Fresh path: guide a user through creating a new infrastructure change spec from scratch.
  • Upgrade path: convert existing IaC artifacts or resource manifests into a structured spec.
  • Integrated tooling: works with arn-infra-request-analyzer and arn-infra-cost-analyst to enrich the spec with analysis and cost estimates.
  • Output and artifacts: writes the spec to INFRA_CHANGE_<name>.md in the infra specs directory; supports blast radius assessment, environment scope, rollback, and compliance considerations.

Quick Start

Describe your infrastructure change idea and I will guide you through turning it into a formal INFRA_CHANGE spec.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert infrastructure ideas into a formal change spec for planning?▼

To create a formal infrastructure change spec, describe your idea or existing IaC artifacts to generate a structured INFRA_CHANGE specification. This output includes blast-radius classification, resource identification, and cost estimation for execution planning.

Can I upgrade existing IaC artifacts into a structured infrastructure change specification?▼

Yes, existing IaC artifacts can be upgraded into a structured change spec. The process transforms your current resource manifests across environments into an actionable INFRA_CHANGE specification for planning and execution.

What is blast-radius classification in infrastructure change planning?▼

Blast-radius classification in infrastructure change planning assesses the potential impact scope of modifications across environments. It is a core component of the generated INFRA_CHANGE specification used to gauge execution risk.

How do I estimate costs when planning an infrastructure change?▼

To estimate costs when planning an infrastructure change, generate an INFRA_CHANGE spec and integrate it with cost analysis tooling. This enriches your specification with detailed cost estimates for identified resources.

What file format does an infrastructure change spec use for project documentation?▼

An infrastructure change spec uses a markdown file format for project documentation. The specification is written to INFRA_CHANGE_<name>.md and stored directly under the project's dedicated infra-specs directory.
