new-course

# new-course Scaffold `courses/<name>/` from `templates/course/`. This skill ONLY copies the template; it does not read materials and does not generate `spec.md`. ## Steps 1. **Verify cwd is the repo root.** Confirm both paths exist relative to cwd: - `templates/course/` - `.claude/skills/new-course/` If either is missing, refuse with: "Run /new-course from the repo root — the folder containing templates/ and .claude/." Stop. 2. **Require the course name.** If `$ARGUMENTS` is empty (or the user did not provide a name in their message), ask: "What should the course be called? It becomes the folder name under courses/." Stop until they answer. 3. **Refuse on collision.** If `courses/$ARGUMENTS/` exists, refuse with: "courses/$ARGUMENTS/ already exists. Pick a different name or remove the existing folder first." Stop. 4. **Copy the template:** ```bash cp -R templates/course/ "courses/$ARGUMENTS/" ``` 5. **Report and hand off.** Tell the user, in this order: 1. "Scaffolded courses/$ARGUMENTS/." 2. "Get notebooks + transcripts from https://course-context-lab.vercel.app — that's where this lab's course materials are produced. Download them yourself; I won't WebFetch from there." 3. "Tip: once they're downloaded, drag the files from Finder into this terminal window. The terminal pastes their absolute paths, and I can `cp` them into courses/$ARGUMENTS/materials/notebooks/ and courses/$ARGUMENTS/materials/transcripts/ — saves tokens versus having me traverse your filesystem." 4. "Then `cd courses/$ARGUMENTS` and run /generate-spec when the materials are in place — say 'go ahead' when you're ready." 5. "Optional extra: if you also want the course's real code, find the course at https://github.com/deeplearningai-eng/courses and run `/ingest-course-repo <course-folder-URL>` before /generate-spec — it adds the `.ipynb` files and `helper.py` under courses/$ARGUMENTS/materials/notebooks/from-repo/. This is an addition to step 2, not a replacement: the notebooks `.md` and the transcripts still come from the site." ## Don't - Don't read or write `materials/`, `spec.md`, `builds/`, or `evals/`. - Don't `cd` for the user — they choose when to move into the course folder. - Don't run from inside an existing course folder. The session is anchored at the repo root. - Don't WebFetch from `course-context-lab.vercel.app` — point the user at it; let them download manually. The agent doesn't pull course content from the web.
