fountain skillA

fountain is agent-read markdown (skill) from managoat/fountain: Operate Fountain (https://managoat.com) — a multi-tenant service that runs sandboxed coding agents (claude/codex/gemini/opencode) inside per-conversation sprites. Use this skill whenever the user asks you to spin up an agent on Fountain, delegate work to another agent, fan out a task across N agents, manage Fountain agents/environments/vaults declaratively, or drive the `fountain` CLI. Reads `FOUNTAIN_API_KEY` (required) and `FOUNTAIN_BASE_URL` (defaults to https://managoat.com)..

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

Latest version
mdr add managoat/fountain/fountain@git:20260910.c04049c
Exact content
mdr add managoat/fountain/fountain@sha256:69bfb4f99c5b7934

Pin 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.
