# argocd-expert

A skill that turns your agent into an ArgoCD operator: GitOps deploys, app sync, AppProject and ApplicationSet. Useful when your deployment lives in Git.

## What it does

The skill gives the agent working knowledge of ArgoCD: `argocd` commands for apps, repos, clusters and projects, plus the Application CRD, AppProject and ApplicationSet. Ask about sync strategies, rollbacks, RBAC or sync waves and you get manifests to go with the answer.

It also carries a set of practices. Turn on `prune` and `selfHeal` in auto-sync. Split apps by component instead of shipping one giant Application. Order resources with `argocd.argoproj.io/sync-wave`. The anti-pattern section covers manual-only sync, missing RBAC and orphaned resources. A reference file, `references/CORE_CONCEPTS.md`, is read on demand.

ArgoCD 2.9 or newer and Kubernetes 1.28 or newer are required. The skill shells out to `argocd` and `kubectl` through Bash, so both CLIs have to be on your PATH — without them the commands won't run.

## Requirements
- Works with: Kubernetes

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add personamanagmentlayer/pcl --skill argocd-expert -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/argocd-expert/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/argocd-expert/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add personamanagmentlayer/pcl --skill argocd-expert -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/argocd-expert/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add personamanagmentlayer/pcl --skill argocd-expert -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/argocd-expert/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install personamanagmentlayer/pcl argocd-expert
```

2. **Manually: put the files in place**
- File: `.github/skills/argocd-expert/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add personamanagmentlayer/pcl --skill argocd-expert -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/personamanagmentlayer/pcl --path stdlib/devops/argocd-expert
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/argocd-expert/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add personamanagmentlayer/pcl --skill argocd-expert -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/personamanagmentlayer/pcl/tree/HEAD/stdlib/devops/argocd-expert/SKILL.md

## When to use it
- set up auto-sync with pruning and self-heal for an app
- order resources with sync waves so they deploy in sequence
- scope team access with project-level RBAC roles
- manage several clusters declaratively with ApplicationSet
- roll back a bad release with `argocd app rollback`

## Example prompts
- Create an Application for the service from our repo, path `k8s/overlays/production`, namespace `production`
- Enable automated sync with `prune: true` and `selfHeal: true` in the syncPolicy
- Add a sync window so deploys only run on weekdays from 9am

# ArgoCD Expert

You are an expert in ArgoCD with deep knowledge of GitOps workflows, application deployment, sync strategies, RBAC, and production operations. You design and manage declarative, automated deployment pipelines following GitOps best practices.

## argocd CLI Commands

**Application Management:**

```bash
# Create application
argocd app create myapp \
  --repo https://github.com/myorg/myapp \
  --path k8s/overlays/production \
  --dest-server https://kubernetes.default.svc \
  --dest-namespace production

# List applications
argocd app list
argocd app list -o wide

# Get application details
argocd app get myapp
argocd app get myapp --refresh

# Sync application
argocd app sync myapp
argocd app sync myapp --prune
argocd app sync myapp --dry-run
argocd app sync myapp --force

# Rollback
argocd app rollback myapp

# Delete application
argocd app delete myapp
argocd app delete myapp --cascade=false  # Keep resources
```

**Repository Management:**

```bash
# Add repository
argocd repo add https://github.com/myorg/myapp \
  --username myuser \
  --password mytoken

# List repositories
argocd repo list

# Remove repository
argocd repo rm https://github.com/myorg/myapp
```

**Cluster Management:**

```bash
# Add cluster
argocd cluster add my-cluster-context

# List clusters
argocd cluster list

# Remove cluster
argocd cluster rm https://cluster.example.com
```

**Project Management:**

```bash
# Create project
argocd proj create production

# Add repository to project
argocd proj add-source production https://github.com/myorg/*

# Add destination to project
argocd proj add-destination production \
  https://kubernetes.default.svc \
  production

# List projects
argocd proj list

# Get project details
argocd proj get production
```

## Best Practices

### 1. Use AppProjects

```yaml
# Separate projects by team/environment
- production
- staging
- development
```

### 2. Enable Auto-Sync with Pruning

```yaml
syncPolicy:
  automated:
    prune: true
    selfHeal: true
```

### 3. Use Sync Waves

```yaml
annotations:
