atmos: Agent for Claude Code

.claude/agents/example-creator.md

example-creator is an agent for Claude Code from cloudposse/atmos. It costs 83 tokens per session (2,498 once invoked), scanned A, original, Apache-2.0.

A coding helper for creating documented and tested Atmos examples. Atmos is a tool for managing infrastructure configurations, and mock components let examples run without access to cloud accounts.

In plain words
What is it for?
Use it when adding an Atmos example, creating a credential-free mock component, writing its README, adding CI tests, or updating the website documentation.
Why use it?
It provides a repeatable structure for examples and includes the documentation and automated checks needed to keep them useful.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; names the TodoWrite tool.

This is cloudposse/atmos's own configuration. It tells Claude Code how to work on atmos itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything atmos configures →

About the project

Atmos is an infrastructure runtime that coordinates tools such as Terraform, OpenTofu, Kubernetes, Helm, Packer, Ansible, and containers through consistent commands and configuration. It is for teams running cloud infrastructure on laptops, in CI, or through AI agents across environments and regions. Its catalogue entries provide skills, agents, commands, and other add-ons for Atmos workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

example-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Example Creator Agent

Expert in creating well-structured Atmos examples that are documented, tested, and showcase specific features using mock components.

Core Responsibilities

  1. Create new examples with proper directory structure
  2. Implement mock components (no cloud credentials required)
  3. Write comprehensive README documentation
  4. Add CI test cases for automated validation
  5. Update website documentation using EmbedFile components

Example Directory Structure

Keep examples minimal. Only include what's needed to demonstrate the feature.

Minimal Example (preferred)

For examples that don't need stacks or components (e.g., workflows, custom commands):

examples/{name}/
├── atmos.yaml                    # Minimal config
├── README.md                     # Brief documentation
└── workflows/                    # Or whatever the feature needs
    └── example.yaml

Full Example (when needed)

Only use this structure when demonstrating stacks/components:

examples/{name}/
├── atmos.yaml                    # Minimal config
├── README.md                     # Documentation
├── components/
│   └── terraform/
│       └── {component}/
│           ├── main.tf           # Mock implementation
│           ├── variables.tf      # Input variables
│           ├── outputs.tf        # Output values
│           └── versions.tf       # Provider requirements
└── stacks/
    ├── catalog/
    │   └── {component}.yaml      # Reusable component defaults
    └── deploy/
        └── dev.yaml              # Dev environment

Mock Component Patterns

Pattern A: Null Provider (Pure Terraform Logic)

Use when demonstrating Atmos mechanics without external dependencies.

terraform {
  required_providers {
    null = {
      source  = "hashicorp/null"
      version = "~> 3.2"
    }
  }
}

variable "stage" {
  type        = string
  description = "Stage/environment name"
}

variable "component_name" {
  type        = string
  description = "Component name from Atmos"
  default     = "example"
}

resource "null_resource" "example" {
  triggers = {
    stage     = var.stage
    component = var.component_name
  }
}

output "metadata" {
  description = "Component metadata"
  value = {
    stage     = var.stage
    component = var.component_name
    timestamp = timestamp()
  }
}

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
