Terraform Arch Mapper

Overview

This skill analyzes Terraform configuration files (.tf ) to extract infrastructure resources and their dependencies. It then generates a visual representation of the system architecture using Mermaid.js or PlantUML.

Capabilities

• Resource Extraction:

• Scans all .tf files in a directory.

• Identifies provider resources (e.g., aws_instance , google_storage_bucket ).

• Relationship Mapping:

• Detects dependencies between resources (e.g., vpc_id = aws_vpc.main.id ).

• Diagram Generation:

• Outputs Mermaid C4 or flowchart code.

• Outputs PlantUML code.

Usage

Generate Mermaid diagram (default)

node scripts/generate_diagram.cjs [path/to/terraform/dir]

Generate PlantUML diagram

node scripts/generate_diagram.cjs [path/to/terraform/dir] --format plantuml

Dependencies

• Node.js environment

• hcl2-parser (for parsing Terraform files)

Knowledge Protocol

• This skill adheres to the knowledge/orchestration/knowledge-protocol.md . It automatically integrates Public, Confidential (Company/Client), and Personal knowledge tiers, prioritizing the most specific secrets while ensuring no leaks to public outputs.
