atmos-lintAtmos Terraform linting with TFLint: standalone atmos terraform lint, component-aware config discovery and toolchain versions, TFLint rule configuration, and lifecycle hooks/CI findings.
Atmos Lint is an agent skill from cloudposse/atmos. Atmos Terraform linting with TFLint: standalone atmos terraform lint, component-aware config discovery and toolchain versions, TFLint rule configuration, and lifecycle hooks/CI findings. Use when configuring, running, debugging, or documenting Terraform/OpenTofu linting in an Atmos project.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/tflint.md`).
It sits in Development, covering Linting and formatting and Infrastructure as code. It works with Terraform. The repository describes itself as: Atmos is the open-source runtime for infrastructure — it builds, authenticates, and ships Terraform, OpenTofu, Packer, Ansible, Kubernetes, Helm, and containers the same way on… The licence is Apache-2.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit fbae93f. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml and bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Atmos Lint loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 406 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

the native atmos terraform lint command for deliberate lint runs and the
tflint hook kind for linting as part of a Terraform lifecycle.
| Need | Use |
|---|---|
| Check one component or every component without plan/apply | atmos terraform lint |
| Check only changed component sources | atmos terraform lint --affected |
| Enforce lint before or after a Terraform action | kind: tflint hook |
| Run a provider-plugin initialization command or a bespoke script | kind: command hook or workflow step |
# All Terraform component directories, once each (default)
atmos terraform lint
atmos terraform lint --all
# A component; Atmos selects a stack context deterministically when needed
atmos terraform lint vpc
atmos terraform lint vpc --stack test
# Changed Terraform components only
atmos terraform lint --affectedAtmos resolves the selected component instance before linting. Declare tflint
under that component's dependencies.tools to pin the binary version; Atmos
installs it and supplies its PATH for that lint execution. A component used by
multiple stacks is linted once, with a deterministic stack context used only to
resolve its settings and toolchain.
components:
terraform:
vpc:
dependencies:
tools:
tflint: "0.59.1"Do not use atmos toolchain install as a prerequisite for normal component
linting when dependencies.tools declares TFLint. Use it only to warm a cache
or troubleshoot an interactive shell. For precedence of tool declarations,
load atmos-toolchain.
When no hook or workflow explicitly passes --config, Atmos finds
.tflint.hcl in this order. The most-specific existing path wins:
components.terraform.base_path)components.terraform.lint.config (an absolute path or a path relative to the Atmos base path)Use the explicit lint.config setting for a nonstandard shared config path:
components:
terraform:
lint:
config: config/tflint/company.hclThe tflint hook and TFLint workflow step use the same discovery. An explicit
--config in their args is intentional and overrides discovery.
Use a component hook when lint must be enforced for normal Terraform commands. Choose the earliest event that gives the desired feedback; static TFLint checks usually belong before init or plan.
components:
terraform:
vpc:
dependencies:
tools:
tflint: "0.59.1"
hooks:
lint:
events:
- before.terraform.plan
kind: tflint
on_failure: failThe built-in hook runs TFLint with --chdir=$ATMOS_COMPONENT_PATH and
--format=sarif. Its default on_failure: warn reports findings without
blocking the Terraform command; set on_failure: fail to make lint gating.
SARIF is captured from stdout and can render terminal summaries, CI annotations,
and code-scanning results.
Use a kind: command hook for provider plugin initialization when required:
hooks:
tflint-init:
events:
- before.terraform.plan
kind: command
command: tflint --chdir=$ATMOS_COMPONENT_PATH --initKeep initialization and lint separate so its network/plugin behavior is clear. Load atmos-hooks for hook inheritance, conditions, and failure handling; load atmos-ci for CI integration.
Read references/tflint.md before changing rules, adding
provider plugins, or selecting TFLint flags. Preserve an existing project's
config style and run the exact component or --affected selection that verifies
the intended scope.

Atmos Terraform linting with TFLint: standalone atmos terraform lint, component-aware config discovery and toolchain versions, TFLint rule configuration, and lifecycle hooks/CI findings. Atmos Lint is an agent skill from cloudposse/atmos. Atmos Terraform linting with TFLint: standalone atmos terraform lint, component-aware config discovery and toolchain versions, TFLint rule configuration, and lifecycle hooks/CI findings.
Atmos Lint fits situations like: documenting Terraform/OpenTofu linting in an Atmos project; tasks that involve Linting and formatting; tasks that involve Infrastructure as code.
Run `npx skills add cloudposse/atmos --skill atmos-lint -a claude-code`. Or copy the skill folder (agent-skills/skills/atmos-lint in cloudposse/atmos) into .claude/skills/atmos-lint in your project. Claude Code loads it when a task matches its description.
Run `npx skills add cloudposse/atmos --skill atmos-lint -a codex`. Or copy the skill folder (agent-skills/skills/atmos-lint in cloudposse/atmos) into .agents/skills/atmos-lint in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cloudposse/atmos --skill atmos-lint -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/atmos-lint, .gemini/skills/atmos-lint, .github/skills/atmos-lint and .opencode/skills/atmos-lint in your project.
SKILL.md names no scripts, command-line tools or credentials: Atmos Lint is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Atmos Lint is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 782 tokens, read only when the agent opens those files.
