代理系统

Claude Code 有 6 种内置代理类型。每种都是为特定目的构建的，具有特定的模型、工具集和权限模式。子代理根据任务自动生成。

6 代理类型 3 使用的不同模型 34M+ 每周生成次数

i Explore 和 Plan 代理省略 CLAUDE.md

Explore 和 Plan 代理故意跳过从上下文加载 CLAUDE.md 和 git 状态。这在 34M+ 次生成时每周节省约 5-15 Gtok。如果你需要这些代理遵循项目约定，请直接在提示词中包含相关规则。

General-Purpose

The default workhorse

Model Inherits from parent

Tools All tools (*)

Use case

Complex research, multi-step search, tasks that require the full tool set

· No tool restrictions
· Model inherits from parent session
· Used when no specialized agent fits

Explore

Read-only codebase explorer

Model Haiku (external) / Inherits (internal)

Tools All except Agent, Edit, Write, ExitPlanMode, NotebookEdit

Use case

Codebase searches, quick lookups, exploring file structure

× Cannot modify files. Cannot spawn sub-agents.

· Uses cheaper Haiku model for external users
· Minimum 3 queries enforced before returning results
· Omits CLAUDE.md from context to save tokens
· Saves ~5–15 Gtok/week at 34M+ spawns

Plan

Architecture and strategy designer

Model Inherits from parent

Tools Read-only (no Edit, Write, Agent, ExitPlanMode)

Use case

Design implementation strategy, identify critical files, consider trade-offs

× Cannot modify files.

· Required output: list of 3–5 critical files for implementation
· Omits CLAUDE.md and git status from context
· Focuses purely on design decisions

Verification

Automated quality gate

Model Inherits from parent

Tools Read-only verification tools

Permission Mode Always runs in background

Use case

Verify implementations are correct after code changes

· Always runs in the background (non-blocking)
· Displays in red in the terminal to stand out
· Must end with one of: VERDICT: PASS, VERDICT: FAIL, or VERDICT: PARTIAL
· Useful as an automated quality gate in CI/CD

Claude Code Guide

Documentation assistant

Model Haiku

Tools Glob, Grep, Read, WebFetch, WebSearch

Permission Mode dontAsk (auto-denies prompts)

Use case

Answer questions about Claude Code features, API, CLI, MCP servers

· Uses cheaper Haiku model
· Auto-denies permission prompts (dontAsk mode)
· Sources: official Claude Code and Anthropic API docs
· Specialized for documentation lookups only

Status Line Setup

Config file editor

Model Sonnet

Tools Read and Edit only

Use case

Configure the Claude Code terminal status line setting

· Extremely restricted tool set: only Read + Edit
· Cannot run shell commands or access the web
· Focused single-purpose agent
