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.
npx agentmods add instructions/kousen/claude-code-training/agents-mdgit clone --depth 1 https://github.com/kousen/claude-code-trainingWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01121 | $0.01121 |
| Opus 5 | $0.00561 | $0.00561 |
| Sonnet 5 | $0.00224 | $0.00224 |
| Haiku 4.5 | $0.00112 | $0.00112 |
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 2d 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.

Development Workflow
Presentation Development
- Run development server:
pnpm dev - Build for production:
pnpm build - Export to PDF locally:
pnpm export(producesslides-export.pdf, gitignored) - Export to PowerPoint:
pnpm export --format pptx --output slides-export.pptx
Note: For local exporting, you may need to install Playwright's Chromium first:
pnpm exec playwright install chromium
Slides PDF distribution
The published PDF is not committed to the repo. .github/workflows/build-slides-pdf.yml auto-builds on every push to main that touches slides.md (or package.json / pnpm-lock.yaml / the workflow itself) and attaches slides-export.pdf to a rolling slides-latest release. Stable URL:
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.
