Infrastructure

A service mesh is an infrastructure layer that provides transparent service-to-service communication with built-in observability, traffic management, and security features without requiring application code changes.

Basic Resource:

Infrastructure standards for infrastructure in Devops environments. Covers

This skill should be used when working with secrets in Ansible playbooks, integrating Infisical vault, using no_log directive, retrieving credentials securely, or implementing fallback patterns for secrets. Covers the reusable Infisical lookup task.

This skill should be used when creating Ansible roles, designing role directory structure, organizing role variables in defaults vs vars, writing role handlers, or structuring role tasks. Based on analysis of 7 production geerlingguy roles.

This skill should be used when writing Ansible playbooks, creating Ansible tasks, running ansible-playbook commands, selecting Ansible modules, or working with Ansible collections. Provides golden rules, FQCN requirements, module selection guidance, and execution patterns using uv run.

Expert Terraform engineer specializing in infrastructure as code, multi-cloud provisioning, and modular architecture. Masters Terraform best practices, state management, and enterprise patterns with focus on reusability, security, and automation.

This skill should be used when creating new Ansible playbooks, designing playbook structure, implementing state-based playbooks with present/absent patterns, organizing plays and tasks, or structuring playbook variables. Covers play organization, variable scoping, and state-based design patterns.

This skill should be used when running ansible-lint, configuring linting rules, testing Ansible playbooks, validating playbook syntax, or setting up integration tests. Covers ansible-lint configuration and testing strategies.

This skill should be used when writing idempotent Ansible tasks, using command or shell modules, implementing changed_when and failed_when directives, creating check-before-create patterns, or troubleshooting tasks that always show "changed".

This skill should be used when implementing error handling in Ansible, using block/rescue/always patterns, creating retry logic with until/retries, handling expected failures gracefully, or providing clear error messages with assert and fail.

Author and operate Terraform with safe plans, reviews, and drift control

Design and deliver core infrastructure with resilient operations

Set up complete experimental infrastructure for all runs in a designed experiment. Orchestrates parallel generation of fine-tuning configs (via scaffold-torchtune) and evaluation configs (via scaffold-inspect). Use after design-experiment to prepare configs before running experiments.

Comprehensive validation methodology for multi-component applications including backend, frontend, database, and infrastructure

Manages Terraform state operations including importing existing resources, moving resources between states, removing resources from state, and migrating state backends. This skill should be used when users need to import infrastructure into Terraform, refactor resource addresses, fix state issues, or migrate state storage locations.

Scaffolds new Terraform modules with standardized structure including main.tf, variables.tf, outputs.tf, versions.tf, and README.md. This skill should be used when users want to create a new Terraform module, set up module structure, or need templates for common infrastructure patterns like VPC, ECS, S3, or RDS modules.

Guide proper usage of Editor UI infrastructure including Drawers (ButtonDrawer, ModalDrawer, TableDrawer, etc.), Elements (drag-drop targets, ComponentSelector), FieldEditors, and EditorUIConstants. Use when implementing editor panels, component editors, or any ImGui UI code to ensure consistency and code reuse.

Guides through Terraform version upgrades including identifying deprecated syntax, updating provider versions, and migrating breaking changes. This skill should be used when users need to upgrade Terraform or provider versions, fix deprecated warnings, or migrate configurations to newer syntax.

Generates documentation for Terraform modules using terraform-docs tool to auto-generate README files with input/output tables, usage examples, and requirements. This skill should be used when users need to document Terraform modules, create or update README files, or maintain consistent module documentation.
