Parallel Agents

# Native Parallel Agents

> Orchestration through Claude Code's built-in Agent Tool

Overview

This skill enables coordinating multiple specialized agents through Claude Code's native agent system. Unlike external scripts, this approach keeps all orchestration within Claude's control.

When to Use Orchestration

✅ **Good for:**

- Complex tasks requiring multiple expertise domains

- Code analysis from security, performance, and quality perspectives

- Comprehensive reviews (architecture + security + testing)

- Feature implementation needing backend + frontend + database work

❌ **Not for:**

- Simple, single-domain tasks

- Quick fixes or 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.

With Context Passing

Use the frontend-specialist to analyze React components.
Based on those 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: Configuration and code review
2. penetration-tester: Active vulnerability testing
3. Synthesize with prioritized remediation

Claude Code Built-in Agents

These work alongside custom agents:

| Agent | Model | Purpose |

|-------|-------|---------|

| **Explore** | Haiku | Fast read-only codebase search |

| **Plan** | Sonnet | Research during plan mode |

| **General-purpose** | Sonnet | Complex multi-step modifications |

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

Synthesis Protocol

After all agents complete, synthesize:
