teachback skillB
teachback is agent-read markdown (skill) from terrylica/cc-skills: Build or deepen a single-file interactive HTML explainer that teaches back difficult material already established in the conversation (or a named subject/source). Use when someone wants a durable, self-contained lesson with rendered mathematics, an exploratory multiple-choice assessment, and a terminology loop that lets the reader push unfamiliar terms back for deeper coverage..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

And when you add a check to a gate, add the > mutation that proves it can fail: an unexercised check is not yet a check. Produces **one HTML file** that explains hard material to an intelligent reader with no assumed specialist background. The page runs from `file://` with no server, no tracking and no framework. The defining behaviour: **teachback reads what is already in the working context.** Do not ask the reader to restate material the conversation already contains. Infer the subject, scope, prerequisites, title, filename and technical depth. > **This copy is canonical.** teachback was built in `Eon-Labs/alpha-forge` and merged there as > [#527](https://github.com/Eon-Labs/alpha-forge/pull/527) after eleven review rounds; it was promoted > to [terrylica/cc-skills](https://github.com/terrylica/cc-skills) on 2026-08-20 to make it available …
