loom-fluxcd

loom-fluxcd is a skill for Claude Code from cosmix/loom. It costs 16 tokens per session (7,189 once invoked), scanned D, original, MIT.

Flux CD guidance for GitOps deployments to Kubernetes. GitOps means storing the desired system configuration in Git and having software continuously make the running cluster match it.

In plain words
What is it for?
Use it to configure Flux controllers, Helm charts, Kustomize overlays, image updates, webhooks, alerts, rollbacks, and multiple teams or environments.
Why use it?
It helps make deployments repeatable and traceable while separating problems in source fetching, configuration building, chart installation, and notifications.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is path: ./apps/production.

Good fit Use it to configure Flux controllers, Helm charts, Kustomize overlays, image updates, webhooks, alerts, rollbacks, and multiple teams or environments.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 D, and why

loom-fluxcd scanned grade D with 3 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 6d 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.

Flux CD GitOps Toolkit

Overview

Declarative GitOps CD: a set of specialized controllers continuously reconcile cluster state toward Git. Flux is CRD-centric with no first-party UI — you drive it with the flux CLI and YAML. The controllers, and the CRDs each owns:

Controller CRDs Role
source-controller GitRepository, OCIRepository, HelmRepository, HelmChart, Bucket Fetch + verify + cache artifacts
kustomize-controller Kustomization Build/apply overlays, prune, health-check, dependsOn ordering
helm-controller HelmRelease Install/upgrade/rollback charts, drift detection
notification-controller Provider, Alert, Receiver Outbound alerts + inbound webhooks
image-reflector / image-automation ImageRepository, ImagePolicy, ImageUpdateAutomation Scan registries, select tags, commit back to Git

The controller separation matters: a Kustomization failure is a kustomize-controller concern; a chart failure is helm-controller. Debug the right one.

When Argo CD vs Flux

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

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

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-fluxcd is a skill published in the GitHub repository cosmix/loom (54 stars, last pushed today), licensed MIT. It adds 16 tokens to every session and 7,189 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
