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 commands/ruizrica/toolkit/code2coursegit clone --depth 1 https://github.com/ruizrica/toolkitWhat 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 | $0.00035 | $0.00579 |
| Opus 5 | $0.00017 | $0.00290 |
| Sonnet 5 | $0.00007 | $0.00116 |
| Haiku 4.5 | $0.00003 | $0.00058 |
Grade A, and why
code2course 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.
How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/code2course — Codebase to Interactive Course
Transform any codebase into a stunning, self-contained HTML course with scroll-based navigation, animated visualizations, embedded quizzes, and code-with-plain-English side-by-side translations.
Target Codebase
Parse $ARGUMENTS to determine the target codebase:
- GitHub URL (e.g.,
https://github.com/user/repo) → Clone it to/tmp/<repo-name>first - Local path (e.g.,
./my-projector/path/to/project) → Use directly - "this" or empty → Use the current working directory
If no argument is provided, introduce yourself:
I can turn any codebase into an interactive course that teaches how it works — no coding knowledge required.
Just point me at a project:
- A local folder — e.g.,
/code2course ./my-project- A GitHub link — e.g.,
/code2course https://github.com/user/repo- The current project —
/code2course this
Instructions
Invoke the bundled codebase-to-course skill and follow its 4-phase process.
The skill lives inside this plugin at:
plugins/toolkit/skills/codebase-to-course/SKILL.md
plugins/toolkit/skills/codebase-to-course/references/design-system.md
plugins/toolkit/skills/codebase-to-course/references/interactive-elements.md
Use the Skill tool (Skill name: codebase-to-course) so Claude Code's skill loader resolves it via the plugin's manifest. If the Skill tool is unavailable, fall back to reading the SKILL.md file directly from the plugin directory.
Process Summary
- Codebase Analysis — deeply understand the target codebase (read all key files, trace data flows, map components)
- Curriculum Design — structure 5–8 modules (do NOT ask for approval — just build it)
- Build the Course — generate a single self-contained HTML file, one module at a time
- Review and Open — open the HTML in the browser for review
Output
Save the generated course HTML file to the current working directory as <project-name>-course.html.
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.
- 2d ago First seen · 54 lines · 35 tokens per session scan A 36222001ea2d
code2course is a command published in the GitHub repository ruizrica/toolkit (5 stars, last pushed 17d ago), licensed MIT. It adds 35 tokens to every session and 579 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
