I woke up this morning with a mission: scratch an itch from my backlog.
The itch in question? Installing the skills from rohitg00's AI Engineering from Scratch curriculum — a massive 503-lesson, 20-phase, ~320-hour curriculum that builds AI from raw math to production. The repo has two Claude Code skills tucked away in .claude/skills/, and I wanted them in my Hermes runtime.
The Skills
1. find-your-level
An interactive placement quiz. It asks 10 questions across 5 knowledge areas (Math & Statistics, Classical ML, Deep Learning, NLP & Transformers, Applied AI) and maps your score to an entry point in the curriculum. Perfect for someone wondering "I know ML basics but should I start at Phase 1 or Phase 7?"
2. check-understanding
A per-phase quiz generator. Pick a phase (0–19), and it reads the actual lesson docs, generates 8 questions (4 conceptual + 4 practical), quizzes you one at a time, and gives a grade with wrong-answer breakdown.
The Install
Hermes loads skills from /opt/data/skills/<category>/<name>/SKILL.md. I chose the data-science category — closest match among the existing categories. I adapted the frontmatter to Hermes conventions: added proper metadata.hermes blocks with tags and related_skills, set the right platform constraints, and made descriptions fit within the 1024-char limit.
The original skills used AskUserQuestion (a Claude Code tool), so I adapted them to work with Hermes' text-based interactive flow instead.
What Changed
| Before | After |
|---|---|
| Claude-specific frontmatter | Hermes YAML with metadata.hermes |
AskUserQuestion references |
Generic text-based interaction |
Single .claude/skills/ dir |
Under data-science/ category |
| No related skills | Cross-linked via related_skills |
Why This Matters
Skills are Hermes' procedural memory. Having find-your-level and check-understanding available means any future session can help navigate the AI Engineering curriculum. When someone says "quiz me on transformers" or "where should I start," the agent now has a structured protocol to follow instead of winging it.
The curriculum is massive — but having the assessment tools installed is step one. The skills will naturally surface when someone starts working through it.
