atmos: Skill for Claude Code

.claude/skills/pull-request/SKILL.md

pull-request is a skill for Claude Code from cloudposse/atmos. It costs 60 tokens per session (3,776 once invoked), scanned A, original, Apache-2.0.

A pull-request checklist for the Atmos project. It explains which release label to use and when a change also needs a changelog post or roadmap update.

In plain words
What is it for?
Preparing or updating an Atmos pull request. It helps classify changes as no release, patch, minor, or major, update related documentation, open the PR, and monitor its checks.
Why use it?
Pull requests can be blocked when required release information is missing or inconsistent. This keeps the release paperwork aligned with the project's automated checks.

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.

  • high Tool Misuse · line 122
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

    Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

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

pull-request 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pull Request Preparation (Atmos)

Use this skill every time you open or update a PR. It encodes three policies that the Atmos repo enforces via CI and that the team has been burned by repeatedly:

  1. Every PR needs exactly one semver label. Unlabeled PRs fail the PR Semver Labels CI check.
  2. minor and major PRs require a blog post AND a roadmap update. The Check for changelog and roadmap updates workflow gates merging on both.
  3. featured[] in the roadmap is curated. Never auto-promote a shipped milestone into featured[] — only the user decides.

If you violate any of these, CI fails and the PR can't merge. Follow this skill across both phases: complete the pre-push checklist before git push, then immediately work through the post-push / PR checklist (open the PR, apply the label, monitor CI).

The label decision tree

The Atmos repo has four mutually exclusive release labels (plus other category labels that don't affect release docs):

Label When CI requires blog + roadmap?
no-release Internal refactor, new internal helper, dependency bump with zero user-visible behavior, docs fixes No
patch Bug fix, performance fix, error-message improvement, small UX polish — user-visible but not a feature No
minor New user-visible feature, new flag, new command, new config option, default flip that users see YES
major Breaking change: removed/renamed flag, schema migration, CLI behavior reversal YES

How to choose

Ask, in order:

  1. Would a user upgrading Atmos see ANY visible change? Behavior, output, errors, performance, new flags, new commands, removed flags, changed defaults? If no, use no-release. This is the most common case for foundation/plumbing PRs.
  2. Is this a breaking change? Removed flags, renamed flags, changed semantics, schema bumps that require user action? Use major. Document the migration in the blog post.
  3. Is this net-new functionality? New command, new flag, new config option that users will adopt? Use minor. Write a blog post.
  4. Anything else user-visible (bug fix, UX polish, error-message rewrite, output formatting): use patch. No blog post required.

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.
