# Cross-Plugin Detective Integration
**Version:** 1.0.0
**Purpose:** Connect ANY agent to the appropriate detective skill based on role
## ⛔ CORE PRINCIPLE: INDEXED MEMORY ONLY
```
╔══════════════════════════════════════════════════════════════════════════════╗
║ ║
║ ALL DETECTIVE SKILLS USE claudemem (INDEXED MEMORY) EXCLUSIVELY ║
║ ║
║ When ANY agent references a detective skill, they MUST: ║
║ ❌ NEVER use grep, find, rg, Glob tool, Grep tool ║
║ ✅ ALWAYS use claudemem search "query" ║

## 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
---
```
---
## Skill Selection Decision Tree
```
┌─────────────────────────────────────────────────────────────────────────────┐
│ WHICH DETECTIVE SKILL TO USE? │
├─────────────────────────────────────────────────────────────────────────────┤
│ │
│ What is the agent's PRIMARY focus? │
│ │
│ ├── IMPLEMENTING code / Finding where to change │
│ │ └── Use: developer-detective │
│ │ │
│ ├── DESIGNING architecture / Understanding patterns │
│ │ └── Use: architect-detective │
│ │ │
│ ├── TESTING / Coverage analysis / Quality │
│ │ └── Use: tester-detective │
│ │ │
│ ├── DEBUGGING / Finding root cause │
│ │ └── Use: debugger-detective │
│ │ │
│ └── COMPREHENSIVE analysis / Technical debt / Audit │
│ └── Use: ultrathink-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
---
## Summary: The Golden Rule
```
╔══════════════════════════════════════════════════════════════════════════════╗
║ ║
║ ANY AGENT + CODE INVESTIGATION = claudemem ONLY ║
║ ║
║ Developer agents → code-analysis:developer-detective ║
║ Architect agents → code-analysis:architect-detective ║
║ Tester agents → code-analysis:tester-detective ║
║ Debugger agents → code-analysis:debugger-detective ║
║ Reviewer agents → code-analysis:ultrathink-detective ║
║ ║
║ grep/find/Glob/Grep = FORBIDDEN (always, everywhere, no exceptions) ║
