concept-builder — the multi-agent "concept-as-a-bundle" workflow

A complete, standalone guide. Any AI agent can read this and operate — no prior context about any specific repo required. Build verified learning material at scale: many concepts, each as rigorous as the first, produced by a subagent swarm you orchestrate.

0. What this is, in one paragraph

A concept bundle is a small set of files that teach ONE idea, where every number, table, and claim is printed by a single runnable ground-truth file (.py/.go/.rs/.ts/.cpp) and pasted verbatim into a static guide (.md), with an optional interactive companion (.html) that recomputes the same logic and proves it with a gold-check badge. You never hand-compute, never trust prose alone. To build many bundles without quality drift, you act as an orchestrator: you write tight per-concept "briefs", launch up to 4 worker subagents in parallel (each owns one bundle's disjoint files), then run a verification sweep that catches every silent failure. Your judgment lives in 5-minute briefs, not 50-minute hand-writes.
