fountain skillA
fountain is agent-read markdown (skill) from binarybourbon/fountain: Spawn and stream Fountain conversations from inside a sprite — use whenever the user asks you to "spin up an agent on Fountain", "delegate to another agent", "fan out", or any task large enough to parallelise across coding agents. Fountain provisions an isolated Sprite per conversation, runs the configured runtime in it, and streams output back over SSE. Reads `FOUNTAIN_BASE_URL`, `FOUNTAIN_TOKEN`, and `FOUNTAIN_CONVERSATION_ID` from the environment..
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.
How to install
mdr add binarybourbon/fountain/fountain@git:20260824.640485dmdr add binarybourbon/fountain/fountain@sha256:b6edc43ae8b72b21Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
