## How to Reference Skills in Agent Frontmatter

### Example: Developer Agent
```yaml
---
name: my-developer-agent
description: Implements features
skills: code-analysis:developer-detective
---

# My Developer Agent

When investigating code, use the developer-detective skill.
This gives you access to indexed memory search via claudemem.

## Investigation Pattern

Before implementing:
1. Check claudemem status: `claudemem status`
2. Search for related code: `claudemem search "feature I'm implementing"`
3. Read specific files from results
4. NEVER use grep or find for discovery
```

### Example: Architect Agent
```yaml
---
name: my-architect-agent
description: Designs architecture
skills: code-analysis:architect-detective
---

# My Architect Agent

When analyzing architecture, use the architect-detective skill.

## Architecture Discovery

1. Check claudemem status: `claudemem status`
2. Search for patterns: `claudemem search "service layer architecture"`
3. Map dependencies: `claudemem search "import dependency injection"`
4. NEVER use grep or find for discovery
```

### Example: Multi-Skill Agent
```yaml
---
name: comprehensive-reviewer
description: Reviews all aspects
skills: code-analysis:ultrathink-detective, code-analysis:tester-detective
---
```

## Integration Examples

### Example 1: Frontend Developer Agent Needing to Find Code

```typescript
// In frontend plugin's typescript-frontend-dev agent:

// ❌ WRONG - Never do this
Grep({ pattern: "UserService", type: "ts" });
Glob({ pattern: "**/user*.ts" });

// ✅ CORRECT - Use indexed memory via developer-detective skill
// The skill teaches the agent to use:
claudemem search "UserService implementation methods"
```

### Example 2: Backend Architect Analyzing API Structure

```typescript
// In bun plugin's api-architect agent:

// ❌ WRONG - Never do this
find . -name "*.controller.ts"
grep -r "router\." . --include="*.ts"

// ✅ CORRECT - Use indexed memory via architect-detective skill
claudemem search "API controller endpoint handler"
claudemem search "router pattern REST GraphQL"
```

### Example 3: Test Architect Finding Coverage Gaps

```typescript
// In frontend plugin's test-architect agent:

// ❌ WRONG - Never do this
Glob({ pattern: "**/*.test.ts" });
Grep({ pattern: "describe" });

// ✅ CORRECT - Use indexed memory via tester-detective skill
claudemem search "test coverage describe spec"
claudemem search "mock stub test assertion"
```

## Skill Inheritance Pattern

When an agent needs code investigation, it should:

1. **Reference the appropriate detective skill in frontmatter**
2. **Follow the skill's INDEXED MEMORY ONLY requirement**
3. **Use claudemem for ALL code discovery**
4. **NEVER fall back to grep/find/Glob/Grep tools**

```yaml
---
name: any-agent-that-needs-investigation
skills: code-analysis:developer-detective  # or architect/tester/debugger/ultrathink
---

# This agent inherits:
# - INDEXED MEMORY requirement (claudemem only)
# - Role-specific search patterns
# - Output format guidance
# - FORBIDDEN: grep, find, Glob, Grep tools
```

---

## Plugin Dependencies

If your plugin has agents that need code investigation, add this dependency:

```json
{
  "name": "your-plugin",
  "dependencies": {
    "code-analysis@mag-claude-plugins": "^1.6.0"
  }
}
```

This ensures:
- claudemem skills are available
- Detective skills are accessible via `code-analysis:*` prefix
- Agents can reference skills in frontmatter
