loom-argocd

loom-argocd is a skill for Claude Code from cosmix/loom. It costs 17 tokens per session (8,898 once invoked), scanned C, original, MIT.

Guidance for using Argo CD to deploy Kubernetes applications from Git. GitOps means that the desired setup is stored in Git, while Argo CD compares it with the running Kubernetes setup and brings them back into agreement.

In plain words
What is it for?
Use it for declarative deployments, synchronization and rollback, multiple Kubernetes clusters, progressive delivery, and continuous delivery managed through Git. It also explains how Argo CD works with tools such as Helm and Kustomize.
Why use it?
It clarifies how to manage deployments, synchronization, health checks, permissions, and differences between the files in Git and what is running. It also helps avoid confusing an application that is healthy with one whose configuration exactly matches Git.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 C, and why

loom-argocd scanned grade C with 1 finding 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

Argo CD GitOps Continuous Delivery

Overview

Declarative GitOps CD for Kubernetes: Git is the source of truth, a controller reconciles cluster state toward it. Vocabulary you must be exact about: target state (Git), live state (cluster), sync (make live match target), OutOfSync (they differ), health (per-resource readiness, distinct from sync), refresh (recompare Git vs live), AppProject (RBAC/resource boundary grouping Applications).

Two facts that trip up most newcomers, stated up front:

  • OutOfSync ≠ unhealthy, and Healthy ≠ InSync. They are orthogonal axes. A perpetually-OutOfSync-but-Healthy app almost always means a controller mutates a field after apply — fix with ignoreDifferences (see Expert Practices), not by re-syncing.
  • Argo CD only inflates manifests (helm template, kustomize build) — it never runs helm install. helm ls/helm rollback show nothing.

When Argo CD vs Flux

Both are CNCF-graduated GitOps controllers; the choice is architectural, not feature-parity.

Concern Argo CD Flux CD
Ordering argocd.argoproj.io/sync-wave annotations within one Application; cross-Application needs ApplicationSet Progressive Sync dependsOn between Kustomizations/HelmReleases + healthChecks gate the next
Composition App-of-apps: one root Application recursing into child Applications Kustomization tree: a Kustomization applies more Kustomizations
Drift correction Opt-in syncPolicy.automated.selfHeal reverts live drift; prune deletes Git-removed resources Continuous reconciliation always re-applies desired state; prune: true GCs by .status.inventory
Fan-out ApplicationSet generators (cluster/git/matrix/PR/SCM) No native generator; per-tenant Kustomizations + image automation
Image updates Not built-in (separate Argo CD Image Updater) First-class ImageRepository/ImagePolicy/ImageUpdateAutomation, commits back to Git
Interface Web UI-centric (topology view, manual sync buttons, RBAC console) CLI/CRD-centric (flux CLI, no first-party UI)
Multi-cluster One control plane syncs many clusters Typically one Flux per cluster pulling its own path

What this file has done since we first saw it

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.

loom-argocd is a skill published in the GitHub repository cosmix/loom (54 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 8,898 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
