atmos-git

atmos-git is a skill for Claude Code from cloudposse/atmos. It costs 54 tokens per session (1,024 once invoked), scanned A, original, Apache-2.0.

A set of Atmos features for managing Git repositories and GitOps workflows. GitOps means using version-controlled files to manage deployments and infrastructure changes.

In plain words
What is it for?
Use it to clone, initialize, update, inspect, compare, commit, push, and clean configured repositories, including repositories used for deployments.
Why use it?
It brings repository operations, authentication, signing, and managed working directories into one configuration-driven workflow. This reduces scattered scripts and manual repository handling.

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

atmos-git 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 3d 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.

Atmos Git

Use this skill for native Git repository management, GitOps automation, managed workdirs, local Git hook shims, signed commits, and GitHub auth through Atmos Auth or Atmos Pro STS.

Configuration

Configure managed repositories in atmos.yaml:

git:
  repositories:
    deployment:
      uri: https://github.com/acme/deployment.git
      branch: main
      auth:
        identity: atmos-pro
      commit:
        author:
          name: Atmos Bot
          email: [email protected]
        signing: auto               # auto | always | never

Use identities or github/sts for private GitHub access. Do not put tokens in repository URIs.

Commands

Command Purpose
atmos git list List configured repositories
atmos git clone <name-or-uri> Clone or reconcile a managed repository
atmos git init <name-or-path> Initialize a managed repository
atmos git pull <name-or-path> Fast-forward pull
atmos git status <name-or-path> Show working tree status
atmos git diff <name-or-path> Show changes
atmos git commit <name-or-path> --message "msg" Stage managed paths and commit
atmos git push <name-or-path> Push commits
atmos git clean <name> Remove managed workdirs

Use atmos git hooks install, run, and uninstall for local Git hook shims in the current repository.

GitOps Guidance

  • Use managed repositories for deployment repos, generated config repos, and promotion workflows.
  • Use signed commits where repository policy requires them; prefer commit.signing: auto unless the workflow requires always or never.
  • Use github/sts in CI so Git subprocesses receive short-lived GitHub App credentials.
  • Use atmos pro commit when CI-generated commits must trigger follow-on GitHub Actions workflows.
  • Keep generated commits traceable with clear messages and commit trailers when the project uses provenance conventions.
