# Built-in Subagents

**Purpose**: Quick reference for Claude Code's default subagents

---

## Explore

**Model**: Haiku (fast, low-latency)
**Tools**: Read-only (denied Write, Edit)
**Purpose**: File discovery, code search, codebase exploration

Thoroughness levels:
- `quick` - Targeted lookups
- `medium` - Balanced exploration
- `very thorough` - Comprehensive analysis

---

## Plan

**Model**: Inherits from main conversation
**Tools**: Read-only (denied Write, Edit)
**Purpose**: Codebase research for planning

Used during plan mode to gather context before presenting a plan. Cannot spawn other subagents.

---

## general-purpose

**Model**: Inherits from main conversation
**Tools**: All tools
**Purpose**: Complex research, multi-step operations, code modifications

Used when task requires both exploration AND modification, complex reasoning, or multiple dependent steps.
