# Skill: agnosticv-validator

**Name:** AgnosticV Catalog Validator
**Description:** Validate AgnosticV configurations against best practices and deployment requirements
**Version:** 1.0.0
**Last Updated:** 2026-01-22

---

## Purpose

Comprehensive validation of AgnosticV catalog configurations before deployment. Checks UUID format, YAML syntax, workload dependencies, category correctness, and best practices to prevent deployment failures.

## Workflow Diagram

![Workflow](workflow.svg)

## What You'll Need Before Starting

Have these ready before running this skill:

**Required:**
- 📁 **Path to catalog directory** - Location of the catalog you want to validate
  - Example: `~/work/code/agnosticv/agd_v2/my-workshop`
  - Example: `/path/to/agnosticv/catalogs/my-demo`
  - Can be relative path if you're in the AgV repo

**The catalog should have:**
- ✅ **common.yaml** (minimum requirement)
- 📋 Optional: dev.yaml, prod.yaml, description.adoc

**Access needed:**
- ✅ Read permissions to the catalog directory
- ✅ Read permissions to AgnosticV repository

**What gets validated:**
- UUID format and uniqueness
- YAML syntax (common.yaml, dev.yaml, prod.yaml)
- Workload dependencies and availability
- Category correctness and structure
- Infrastructure recommendations
- Best practices compliance
- Asset metadata completeness

**Good to know:**
- Validation produces errors (must fix), warnings (should fix), and suggestions (nice to have)
- Best run BEFORE creating a PR
- Can run multiple times as you fix issues

---

## When to Use This Skill

Use `/agnosticv-validator` when you need to:

- Validate a new catalog before creating PR
- Troubleshoot catalog deployment failures
- Check catalog quality before testing in RHDP
- Verify updates to existing catalogs
- Ensure best practices compliance

**Prerequisites:**
- AgnosticV repository cloned locally
- Catalog files exist (common.yaml minimum)
- Git configured and repository accessible

## Configuration Detection

### Get AgnosticV Repository Path (For Full Repo Validation)

**Check configuration files for AgV repository path:**

Checks these locations in order:
1. `~/CLAUDE.md`
2. `~/claude/*.md`
3. `~/.claude/*.md`

```bash
# Check configuration files for AgV path (multiple locations)
agv_repo_path=""

# Check ~/CLAUDE.md first
if [[ -f ~/CLAUDE.md ]]; then
  agv_repo_path=$(grep -E "agnosticv.*:" ~/CLAUDE.md | grep -oE '(~|/)[^ ]+' | head -1)
fi

# Check ~/claude/*.md if not found
if [[ -z "$agv_repo_path" ]]; then
  for file in ~/claude/*.md; do
    [[ -f "$file" ]] && agv_repo_path=$(grep -E "agnosticv.*:" "$file" | grep -oE '(~|/)[^ ]+' | head -1)
    [[ -n "$agv_repo_path" ]] && break
  done
fi

# Check ~/.claude/*.md if still not found
if [[ -z "$agv_repo_path" ]]; then
  for file in ~/.claude/*.md; do
    [[ -f "$file" ]] && agv_repo_path=$(grep -E "agnosticv.*:" "$file" | grep -oE '(~|/)[^ ]+' | head -1)
    [[ -n "$agv_repo_path" ]] && break
  done
fi

# Expand tilde if present
[[ "$agv_repo_path" =~ ^~ ]] && agv_repo_path="${agv_repo_path/#\~/$HOME}"
```

**If found in configuration:**
```
✓ Found AgV repository path: [path from configuration]
```

**If NOT found, will ask when needed for full repository validation.**

---

## Step 1: Smart Path Detection (FIRST)

### Auto-detect Catalog Location

**Check current directory for AgV catalog structure:**

```bash
# Look for common.yaml in current directory or parent
if [ -f "common.yaml" ]; then
  CATALOG_PATH=$(pwd)
elif [ -f "../common.yaml" ]; then
  CATALOG_PATH=$(cd .. && pwd)
elif [ -f "../../common.yaml" ]; then
  CATALOG_PATH=$(cd ../.. && pwd)
fi

# Verify it's an AgV catalog
if [ -f "$CATALOG_PATH/common.yaml" ]; then
  # Extract catalog slug from path
  CATALOG_SLUG=$(basename $CATALOG_PATH)
  CATALOG_DIR=$(basename $(dirname $CATALOG_PATH))
fi
```

### Ask User

```
🔍 AgnosticV Catalog Validator

I'll validate your AgnosticV catalog configuration.

Current directory: {{ current_directory }}

{% if common_yaml_detected %}
✅ Detected catalog:
   Path: {{ detected_catalog_path }}
   Directory: {{ catalog_dir }}/{{ catalog_slug }}

Use this catalog? [Yes/No/Specify different path]
{% else %}
No catalog detected in current directory.

Options:
1. Specify catalog path (e.g., ~/work/code/agnosticv/agd_v2/my-catalog)
2. Validate entire AgnosticV repository (all catalogs)
3. Exit

Your choice: [1/2/3]
{% endif %}
```

### Path Validation

```python
import os

if os.path.exists(catalog_path):
  if os.path.isfile(f"{catalog_path}/common.yaml"):
    ✅ Valid catalog path
    Path: {{ catalog_path }}
    
    # Extract catalog information
    catalog_slug = os.path.basename(catalog_path)
    catalog_dir = os.path.basename(os.path.dirname(catalog_path))
    
    Files found:
    ✓ common.yaml
    {{ '✓ description.adoc' if os.path.exists(f"{catalog_path}/description.adoc") else '⚠ description.adoc (missing)' }}
    {{ '✓ dev.yaml' if os.path.exists(f"{catalog_path}/dev.yaml") else 'ℹ dev.yaml (optional, not found)' }}
    
  else:
    ❌ Path exists but no common.yaml found
    
    Expected file: {{ catalog_path }}/common.yaml
    
    Is this an AgV catalog directory? [Yes - Continue anyway / No - Try different path]
else:
  ❌ Path not found: {{ catalog_path }}
  
  Try again? [Yes/No]
```

**Store validated path** for validation checks.

---

## Step 2: Validation Scope Selection

```
Q: What level of validation do you want?

1. ⚡ Quick check (file structure, UUID, basic YAML)
   Duration: ~5 seconds
   Checks: Essential blocking issues only
   
2. ✅ Standard validation (recommended)
   Duration: ~15-30 seconds
   Checks: Files, UUID, YAML, workloads, schema, best practices
   
3. 🔬 Full validation (everything + GitHub API)
   Duration: ~30-60 seconds
   Checks: Standard + GitHub tag/branch validation, collection URLs

Recommended: 2 (Standard)

Your choice: [1/2/3]
```

**Set validation scope:**

```python
if choice == 1:
  validation_scope = "quick"
  checks_to_run = ["file_structure", "uuid", "yaml_syntax"]
  
elif choice == 2:
  validation_scope = "standard"
  checks_to_run = ["file_structure", "uuid", "yaml_syntax", "category",
                   "workloads", "authentication", "showroom", "infrastructure",
                   "stage_files", "multiuser", "bastion", "collections",
                   "deployer", "reporting_labels", "components", "asciidoc",
                   "best_practices"]

elif choice == 3:
  validation_scope = "full"
  checks_to_run = ["file_structure", "uuid", "yaml_syntax", "category",
                   "workloads", "authentication", "showroom", "infrastructure",
                   "stage_files", "multiuser", "bastion", "collections",
                   "deployer", "reporting_labels", "components", "asciidoc",
                   "best_practices", "github_api", "collection_urls", "scm_refs"]
```

---

## Step 3: Run Validation Checks

### Initialize Error Collection

```python
errors = []         # ERRORS (must fix) - Block deployment
warnings = []       # WARNINGS (should fix) - May cause issues  
suggestions = []    # SUGGESTIONS (nice to have) - Best practices
passed_checks = []  # Passed checks for summary
```

### Check 1: File Structure

```python
def check_file_structure(catalog_path):
  """Required files validation"""
  
  required_files = ["common.yaml"]
  recommended_files = ["description.adoc", "dev.yaml"]
  
  # Check required
  for file in required_files:
    filepath = f"{catalog_path}/{file}"
    if os.path.exists(filepath):
      passed_checks.append(f"✓ Required file present: {file}")
    else:
      errors.append({
        'check': 'file_structure',
        'severity': 'ERROR',
        'message': f'Missing required file: {file}',
        'location': catalog_path,
        'fix': f'Create {file} in catalog directory'
      })
  
  # Check recommended
  for file in recommended_files:
    filepath = f"{catalog_path}/{file}"
    if not os.path.exists(filepath):
      warnings.append({
        'check': 'file_structure',
        'severity': 'WARNING',
        'message': f'Recommended file missing: {file}',
        'location': catalog_path,
        'fix': f'Create {file} for better catalog quality'
      })
```

### Check 2: UUID Format and Uniqueness

```python

    })
    return
  
  passed_checks.append(f"✓ UUID format valid: {uuid}")
  passed_checks.append(f"✓ UUID is unique")

def search_uuid_in_repo(uuid, repo_path, current_catalog):
  """Search for UUID in all catalogs"""
  import glob
  
  for catalog in glob.glob(f"{repo_path}/**/common.yaml", recursive=True):
    if os.path.dirname(catalog) == current_catalog:
      continue  # Skip current catalog
    
    with open(catalog) as f:
      try:
