A Claude Code and Codex Skill for Deliberate Skill Development

I'm not familiar with Skills, but looking at the repo I find the amount of decorative code/text as overkill for what amounts to just the following prompt in a bash script (yikes) executing after a commit is run:

    {"hookSpecificOutput":{"hookEventName":"PostToolUse","additionalContext":"[learning-opportunities-auto] The user just committed code. Per the learning-opportunities skill, consider whether this is a good moment to offer a learning exercise. If the committed work involved new files, schema changes, architectural decisions, refactors, or unfamiliar patterns, ask the user (one short sentence) if they'd like a 10-15 minute exercise. Do not start the exercise until they confirm. If they decline, note it — no more offers this session."}}

I really love the idea, I've had Claude make textbooks for me on the fly using open source textbooks and documentation. Is it possible to extend this skill to more generalized areas of learning / application? Or, is it domain specific to code?

What exactly is the "adaptive dynamic textbook approach"?

Examples?

> Generation effect: Accepting generated code and decreasing generating one's own code can skip the active processing that builds understanding.

Holy truth.

No benchmarks and evals present, how do you know it produces better result than /create-skill ? Naive testing doesn't provide any confidence

Looks interesting! I know it's easy to setup and test it but I'm on mobile current so I think it'd be great if there was full-interaction example to better understand how it works.

Mhh, interesting.

I want to learn Java spring, and probably let ai help me / quiz me. I will take a look into the skills for inspiration.
