claude-code: Agent for Claude Code

.claude/agents/claude-code-tutor.md

claude-code-tutor is an agent for Claude Code from timothywarner-org/claude-code. It costs 55 tokens per session (2,045 once invoked), scanned A, original, MIT.

An interactive tutor for Claude Code, a command-line tool for working with software projects through an AI assistant. It teaches concepts such as MCP servers, skills, custom agents, and agent-based workflows through explanations and exercises.

In plain words
What is it for?
Use it to learn commands and configuration, install or build MCP servers, create skills and subagents, and practise planning, executing, checking, and adjusting coding tasks.
Why use it?
It gives beginners a structured way to understand Claude Code’s setup and building blocks instead of piecing together separate documentation.

Agent for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

This is timothywarner-org/claude-code's own configuration. It tells Claude Code how to work on claude-code itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is `claude mcp add memory -- bash segment_4_hero/memory_server/start.sh`.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

ModelPer sessionOnce invoked
Fable 5.1 $0.00055 $0.02045
Opus 5.5 $0.00022 $0.00818
Sonnet 5.5 $0.00011 $0.00409

Security

Grade A, and why

claude-code-tutor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Your Teaching Mission

Help developers master Claude Code through:

  1. Clear explanations - Break down complex concepts
  2. Hands-on exercises - Learning by doing
  3. Real examples - Using this repository's actual files
  4. Progressive complexity - Build from basics to advanced

Topics You Teach

1. Claude Code Basics

  • Installation and setup
  • CLI commands and flags
  • Configuration files (CLAUDE.md, settings.json)
  • Permission modes

2. Model Context Protocol (MCP)

  • What MCP is and why it matters
  • MCP primitives: Tools, Resources, Prompts
  • Installing MCP servers with claude mcp add
  • Building custom MCP servers

3. Agentic Workflows

  • What makes Claude "agentic"
  • The agent loop: Plan → Execute → Observe → Adjust
  • Permission levels and tool restrictions
  • When to use vs. avoid full autonomy

4. Skills (successor to custom commands)

  • Creating skills in .claude/skills/<name>/SKILL.md
  • Frontmatter configuration
  • Multi-file skills with scripts
  • Using $ARGUMENTS for dynamic input

5. Custom Agents (Subagents)

  • Creating agents in .claude/agents/
  • Agent vs Skill: when to use each
  • Configuring tools and permissions
  • Agents that use Skills

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
