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 5.1 | $0.00032 | $0.01907 |
| Opus 5.5 | $0.00013 | $0.00763 |
| Sonnet 5.5 | $0.00006 | $0.00381 |
| Haiku 4.5 | $0.00003 | $0.00191 |
Grade A, and why
course-creator 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 16d 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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Builder - Course Creator
This skill creates structured, engaging educational content using the project's specialized markdown block system. It supports two distinct course formats. If the requested format is unclear, default to guided_challenge for online interactive tutorial courses.
When to Use This Skill
- User wants to create a new educational course, module, or assignment.
- User wants to design a quiz, walkthrough, or interactive tutorial.
- User provides a topic and asks for a structured learning path.
- User needs to update an existing course with new interactive elements.
Your Roles in This Skill
- Product Manager: Define the course goal, audience, duration, and the appropriate course type.
- Technical Writer: Draft content with clarity, accuracy, and a tone that matches the audience.
- Project Manager: Structure content into a coherent sequence of sections or steps.
- Backend Developer: Implement interactive elements using the specialized markdown blocks.

Two Supported Course Types
The first decision is which format fits the task. Use an explicit user request when one is provided. If the user asks for an online interactive tutorial course but does not state a type, default to guided_challenge.
Type 1: guided_challenge (step-gated assignment)
A staged, app-driven assignment rendered by course.block.tsx. Every visible piece of content lives inside a fenced code block; narration outside fences is ignored. Steps advance via control blocks, quizzes gate progression, terminal commands can be validated server-side, and progress is tracked.
Use this when the learner should be walked through a sequence with checkpoints (interactive coding, terminal validation, forms, container provisioning, etc.).
File location: workspace/learning/{slug}.md by default. If the user or calling tool provides an explicit output file path, write the course to that exact path instead.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

course-creator is a skill published in the GitHub repository X-School-Academy/skill-pilot (20 stars, last pushed 4mo ago), licensed MIT. It adds 32 tokens to every session and 1,907 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-02.

exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
