build-decisioning-signal-marketplace skillA

build-decisioning-signal-marketplace is agent-read markdown (skill) from adcontextprotocol/adcp-client: Build an AdCP signal-marketplace OR signal-owned decisioning platform — a data provider serving audience signals to buyers. Use when the user wants the typed `DecisioningPlatform` shape; for fork-an-adapter starting points, see `build-signals-agent`..

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 adcontextprotocol/adcp-client/build-decisioning-signal-marketplace@git:20260818.e0d722b
Exact content
mdr add adcontextprotocol/adcp-client/build-decisioning-signal-marketplace@sha256:22894b389e2b3bd4

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.
