Native Parallel Agents

Orchestration via Claude Code's built-in Agent Tool

Overview

Coordinate multiple specialized agents through Claude Code's native agent system. Keeps all orchestration within Claude's control (no external scripts).

When to Use

Good for:

• Tasks requiring multiple expertise domains
• Code analysis from security, performance & quality perspectives
• Comprehensive reviews (architecture + security + testing)
• Feature impl needing backend + frontend + db work

Not for:

• Single-domain tasks
• Quick fixes | small changes
• Tasks where one agent suffices

---

Native Agent Invocation

Single Agent

Use the security-auditor agent to review authentication

Sequential Chain

First, use the explorer-agent to discover project structure.
Then, use the backend-specialist to review API endpoints.
Finally, use the test-engineer to identify test gaps.

W/ Context Passing

Use the frontend-specialist to analyze React components.
Based on findings, have the test-engineer generate component tests.

Resume Previous Work

Resume agent [agentId] and continue with additional requirements.

Orchestration Patterns

Pattern 1: Comprehensive Analysis

Agents: explorer-agent -> [domain-agents] -> synthesis

1. explorer-agent: Map codebase structure
2. security-auditor: Security posture
3. backend-specialist: API quality
4. frontend-specialist: UI/UX patterns
5. test-engineer: Test coverage
6. Synthesize all findings

Pattern 2: Feature Review

Agents: affected-domain-agents -> test-engineer

1. Identify affected domains (backend? frontend? both?)
2. Invoke relevant domain agents
3. test-engineer verifies changes
4. Synthesize recommendations

Pattern 3: Security Audit

Agents: security-auditor -> penetration-tester -> synthesis

1. security-auditor: Config & code review
2. penetration-tester: Active vulnerability testing
3. Synthesize w/ prioritized remediation

Claude Code Built-in Agents

Agent	Model	Purpose
Explore	Haiku	Fast read-only codebase search
Plan	Sonnet	Research during plan mode
General-purpose	Sonnet	Multi-step modifications

Use Explore for quick searches, custom agents for domain expertise.

Synthesis Protocol

After all agents complete:

## Orchestration Synthesis

### Task Summary
[What was accomplished]

### Agent Contributions
| Agent | Finding |
|-------|---------|
| security-auditor | Found X |
| backend-specialist | Identified Y |

### Consolidated Recommendations
1. **Critical**: [Issue from Agent A]
2. **Important**: [Issue from Agent B]
3. **Nice-to-have**: [Enhancement from Agent C]

### Action Items
- [ ] Fix critical security issue
- [ ] Refactor API endpoint
- [ ] Add missing tests

Best Practices

1. 17 specialized agents available for orchestration
2. Logical order - Discovery -> Analysis -> Impl -> Testing
3. Share context - Pass findings to subsequent agents
4. Single synthesis - One unified report, not separate outputs
5. Verify changes - Always include test-engineer for code mods

Key Benefits

• Single session - All agents share context
• AI-controlled - Claude orchestrates autonomously
• Native integration - Works w/ built-in Explore, Plan agents
• Resume support - Can continue previous agent work
• Context passing - Findings flow between agents
