Free 100-lesson courses on any subject: search the library, read a course. No key.
Scored across 3 tools
Each tool maps to a distinct level of the content hierarchy: search_subjects finds subjects, get_course retrieves the full course plan, and get_lesson retrieves a single lesson. The descriptions explicitly cross-reference each other (slug from search_subjects), leaving no realistic chance of misselection.
All three names follow a clean verb_noun snake_case pattern: search_subjects, get_course, get_lesson. The 'get_' prefix is used consistently for retrieval and 'search_' for discovery.
Three tools is minimal but each earns its place in a read-only content server (discover -> course -> lesson). It sits at the low edge of the comfortable range, with no obvious redundant or missing tool at this granularity.
The surface covers the core read path: search, course summary/plan, and individual lesson retrieval. Minor gaps exist — no way to list all subjects without a query, and no progress or navigation helper (e.g., next/previous lesson) — but agents can work around these.
