Written for Claude Code and Codex and OpenCode: $ARGUMENTS substitution, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is kousen/claude-code-training's own configuration. It tells Claude Code, Codex and OpenCode how to work on claude-code-training itself, so it is not a mod to install elsewhere.

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.

Security

Grade A, and why

claude-code-training AGENTS.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 24d 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.

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.

Project Structure & Standards

Core Course Materials

  • slides.md: Main Slidev presentation with progressive learning path
  • lab_handout.md: Six progressive hands-on labs (Lab 0-6) for students
  • instructor-guide.md: Detailed instructor guidance with specific demo scenarios
  • exercises/: Collection of real-world sample projects across multiple languages

Sample Projects Architecture

  • Python Projects:
    • weather-app: Clean Flask application for feature addition exercises
    • flask-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 generation
    • shopping-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.

Development Workflow

Presentation Development

  1. Run development server: pnpm dev
  2. Build for production: pnpm build
  3. Export to PDF locally: pnpm export (produces slides-export.pdf, gitignored)
  4. Export to PowerPoint: pnpm export --format pptx --output slides-export.pptx

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.
