simmer-preflight skillA

simmer-preflight is agent-read markdown (skill) from spartanlabsxyz/simmer-sdk: Pre-trade readiness check for autonomous agents. One call returns wallet identity, venue status, spendable balance, open exposure, and a structured ok_to_trade verdict. Run before every real-money trade to prevent cap overruns and catch config issues before they become P&L issues..

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 spartanlabsxyz/simmer-sdk/simmer-preflight@v0.3.3
Exact content
mdr add spartanlabsxyz/simmer-sdk/simmer-preflight@sha256:505d8381caefcce5

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.
