Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01344 | $0.01344 |
| Opus 5 | $0.00672 | $0.00672 |
| Sonnet 5 | $0.00269 | $0.00269 |
| Haiku 4.5 | $0.00134 | $0.00134 |
Grade A, and why
claude-code-training CLAUDE.md 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 3d 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.
This is a copy
88% identical to claude-code-training AGENTS.md — 36 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Training Course Development
This project contains comprehensive training materials for teaching Claude Code to professional software developers. The course emphasizes practical, hands-on learning with real-world scenarios.
Cross-tool conventions
Claude Code does not natively read AGENTS.md (the convention used by Codex and other tools). To pick up shared cross-tool conventions in this repo, this file imports it explicitly:
@AGENTS.md
This is the recommended bridge pattern when a project needs to expose the same guidance to both Claude Code and AGENTS.md-aware tools without duplicating content.
Project Structure & Standards
Core Course Materials
slides.md: Main Slidev presentation with progressive learning pathlab_handout.md: Six progressive hands-on labs (Lab 0-6) for studentsinstructor-guide.md: Detailed instructor guidance with specific demo scenariosexercises/: Collection of real-world sample projects across multiple languages
Sample Projects Architecture
- Python Projects:
weather-app: Clean Flask application for feature addition exercisesflask-api: Intentionally poorly-written API for refactoring demonstrations
- JavaScript/TypeScript:
lyrics-trainer: Interactive web app with TypeScript and comprehensive test suite
- Java Projects:
certificate-service: Modern Spring Boot application with PDF generationshopping-service: Legacy Grails/Groovy application for modernization exercises
Skills and Custom Commands Integration
custom-commands.md: Skills-first walkthrough with a backwards-compat callout for.claude/commands/skills/: Ready-to-copy skill directories migrated from the older command form. Each demonstrates a different frontmatter capability (paths, allowed-tools, context: fork, disable-model-invocation, $ARGUMENTS).commands/: One legacy.claude/commands/example (docs.md) preserved so students can compare old and new forms.skills-and-plugins/: Larger teaching-library skills used during Lab 6 (api-documentation-skill, spring-boot-skill, security-review-skill, plus a plugin example).- Skills cover Java modernization, Spring scaffolding, security reviews, documentation generation, and onboarding automation.
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.

claude-code-training CLAUDE.md is an instructions file published in the GitHub repository kousen/claude-code-training (335 stars, last pushed 6d ago), licensed MIT. It adds 1,344 tokens to every session, about $0.0067 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to claude-code-training AGENTS.md, differing in 36 lines, and is treated as a copy.
