n8n skillA
n8n is agent-read markdown (skill) from tonydzi/second-brain-starter-kit: Health-check, audit and, on approval, fix a self-hosted n8n automation stack. Health is read-only; any workflow edit goes preview, approval, apply. Triggers: "/n8n", "/n8n health", "/n8n fix <id>", "which workflows are failing"..
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 tonydzi/second-brain-starter-kit/n8n@git:20260908.2ec1bf8mdr add tonydzi/second-brain-starter-kit/n8n@sha256:2f206e59cf50512dPin 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.
