> Load the skill catalog for workflow building. This skill should be used when

someone says "what looplia skills are installed", "list available skills", "/build",

# Registry Loader

Load the skill catalog for workflow building and skill discovery.

## Purpose

Provides fast access to the skill catalog for the build pipeline.
Uses the pre-compiled `~/.looplia/registry/skill-catalog.json` instead of runtime scanning.

## Behavior

1. Read the skill catalog from `~/.looplia/registry/skill-catalog.json`
2. If catalog doesn't exist, return empty registry with instructions to run `looplia registry sync`
3. Return catalog data for skill-capability-matcher

## Process

### 1. Load Skill Catalog

Read the skill catalog file:

```bash
cat ~/.looplia/registry/skill-catalog.json
```

Or use the Read tool to access the file directly.

### 2. Parse Catalog Data

The skill catalog contains:

```json
{
  "compiledAt": "2026-01-04T12:00:00Z",
  "version": "1.0.0",
  "sources": [
    {
      "id": "official",
      "type": "official",
      "url": "https://github.com/memorysaver/looplia-core/releases/latest/download/registry.json",
      "enabled": true,
      "priority": 100
    }
  ],
  "skills": [
    {
      "name": "media-reviewer",
      "title": "Media Reviewer",
      "description": "Deep content analysis (structure, themes, narrative)",
      "plugin": "looplia-writer",
      "category": "analysis",
      "capabilities": ["content-analysis", "media-processing"],
      "tools": ["Read", "Grep", "Glob"],
      "model": "claude-haiku-4-5-20251001",
      "source": "local",
      "sourceType": "builtin",
      "installed": true,
      "installedPath": "/home/user/.looplia/looplia-writer/skills/media-reviewer"
    }
  ],
  "summary": {
    "totalSkills": 14,
    "byCategory": {
      "analysis": 3,
      "generation": 2,
      "assembly": 2,
      "validation": 1,
      "search": 1,
      "orchestration": 3,
      "utility": 2
    },
    "bySource": {
      "local": 14
    }
  }
}
```

### 3. Format for skill-capability-matcher

Transform the skill catalog into the format expected by skill-capability-matcher:

```json
{
  "plugins": [
    {
      "name": "looplia-writer",
      "path": "~/.looplia/looplia-writer",
      "skills": [
        {
          "name": "media-reviewer",
          "description": "Deep content analysis (structure, themes, narrative)",
          "tools": ["Read", "Grep", "Glob"],
          "model": "haiku",
          "capabilities": ["content-analysis", "media-processing"],
          "installed": true
        }
      ]
    }
  ],
  "summary": {
    "totalPlugins": 2,
    "totalSkills": 14,
    "installedSkills": 14,
    "availableSkills": 0
  }
}
```

## Output Schema

```json
{
  "plugins": [
    {
      "name": "string",
      "path": "string",
      "skills": [
        {
          "name": "string",
          "description": "string",
          "tools": ["string"],
          "model": "string",
          "capabilities": ["string"],
          "installed": "boolean"
        }
      ]
    }
  ],
  "summary": {
    "totalPlugins": "number",
    "totalSkills": "number",
    "installedSkills": "number",
    "availableSkills": "number"
  }
}
```

## Advantages over plugin-registry-scanner

| Aspect | plugin-registry-scanner | registry-loader (v0.7.0) |
|--------|------------------------|--------------------------|
| Speed | Scans filesystem at runtime | Reads pre-compiled JSON |
| Sources | Local only | Official + third-party |
| Installation Status | Not tracked | Included in output |
| Third-party Skills | Not discovered | Included from remote registries |

## Usage

This skill is typically invoked as the first step in workflow building:

1. Load skill catalog (this skill)
2. Pass catalog to skill-capability-matcher
3. Use matched skills in workflow-schema-composer

## Notes

- If skill catalog doesn't exist, advise user to run `looplia registry sync`
- Catalog is auto-synced on every `looplia build` command
- Includes installation status for each skill
- Third-party skills may show `installed: false` until installed via `looplia skill add`
