# Ark Analysis

This skill helps you analyze the Ark codebase by cloning the repository and examining its contents.

## When to use this skill

Use this skill when:
- User asks "how does X work in Ark?"
- User wants to understand Ark's architecture or implementation
- User needs to examine Ark source code, CRDs, or controllers
- User mentions analyzing the Ark repository

## Quick start

Clone the Ark repository to a temporary location:

```bash
git clone [email protected]:mckinsey/agents-at-scale-ark.git /tmp/ark-analysis
cd /tmp/ark-analysis
```

## Codebase structure

The Ark repository is organized as follows:

- **`ark/`** - Kubernetes operator (Go)
  - Controllers managing AI resources
  - Custom Resource Definitions (CRDs)
  - Webhooks for validation

- **`services/`** - Supporting services (Go, Python, TypeScript)
  - `postgres-memory/` - Memory persistence
  - `ark-api/` - REST API
  - `ark-evaluator/` - Model evaluation

- **`samples/`** - Example configurations (YAML)
  - Agent definitions and queries
  - Multi-agent teams
  - A2A server examples

- **`docs/`** - Documentation site (Next.js)

## Common analysis tasks

### Find controllers
```bash
ls ark/internal/controller/
grep -r "Reconcile" ark/internal/controller/
```

### Find CRDs
```bash
ls ark/config/crd/bases/
grep -r "kind: Agent" samples/
```

### Find A2A implementations
```bash
find . -path "*/a2a*" -type f
grep -r "A2AServer" .
```

### Search for specific features
```bash
# Use ripgrep or grep to search
rg "query controller" --type go
grep -r "team coordination" --include="*.go"
```

## Best practices

1. **Clone to /tmp**: Always clone to `/tmp/ark-analysis` to avoid cluttering the workspace
2. **Navigate first**: `cd /tmp/ark-analysis` before running analysis commands
3. **Use search tools**: Prefer `rg` (ripgrep) or `grep` for code searches
4. **Check CLAUDE.md**: Look for project-specific guidance in `CLAUDE.md` files
5. **Clean up**: Optionally remove the temp directory when done: `rm -rf /tmp/ark-analysis`

## Example workflows

### Analyzing a controller
```bash
git clone [email protected]:mckinsey/agents-at-scale-ark.git /tmp/ark-analysis
cd /tmp/ark-analysis
cat ark/internal/controller/query_controller.go
grep -r "ExecuteQuery" ark/internal/genai/
```

### Understanding A2A integration
```bash
cd /tmp/ark-analysis
find samples/a2a -name "*.py"
cat samples/a2a/simple-agent/src/simple_a2a_server/main.py
cat docs/content/developer-guide/building-a2a-servers.mdx
```

### Finding CRD specifications
```bash
cd /tmp/ark-analysis
ls ark/api/v1prealpha1/
cat ark/api/v1prealpha1/agent_types.go
```
