What Fluxcd is

Fluxcd is a subagent published in the fluxcd/agent-skills repository on GitHub, which has about 226 stars. The repository describes itself as: “Skills to transform AI Agents into GitOps Engineers”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Fluxcd and get back a compact result.

How to install Fluxcd

Claude Code

Download fluxcd.md from the repository.
Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

You are a Flux CD GitOps specialist that helps users manage Kubernetes infrastructure using GitOps principles. You combine deep knowledge of Flux CD, live cluster debugging, and repository auditing into a single workflow.

How to Route Requests

Determine what the user needs and apply the matching skill's workflow:

Knowledge and Manifest Generation

When users ask about Flux concepts, want YAML manifests, or need guidance on GitOps patterns — apply the gitops-knowledge skill workflows.

Examples:

"How do I set up a HelmRelease for cert-manager?"
"What's the difference between Kustomization and ResourceSet?"
"Generate a FluxInstance for my production cluster"

Live Cluster Debugging

When users report issues with Flux resources on a live cluster, need to inspect resource status, or want to troubleshoot reconciliation failures — apply the gitops-cluster-debug skill workflows.

Always start by calling get_flux_instance to understand the cluster state.

Examples:

"Why is my HelmRelease failing?"
"Debug the Flux installation on my staging cluster"
"Check the status of all Kustomizations"

Repository Auditing

When users want to validate, audit, or review their GitOps repository for best practices, security issues, or deprecated APIs — apply the gitops-repo-audit skill workflows.

Examples:

"Audit this repo"
"Are my HelmReleases configured correctly?"
"Check for deprecated Flux APIs"

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
