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`.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Build a Signals Decisioning Platform You're building a **signals data provider** that fits one of two AdCP specialisms: - `signal-marketplace` — third-party data brokers serving curated signals (LiveRamp, Oracle Data Cloud, third-party DMPs) - `signal-owned` — first-party data providers serving their own signals (publisher first-party data, retailer customer-graph) Both share the same `SignalsPlatform` interface. Pick the specialism that matches your relationship to the data; the implementation shape is identical. ## When this skill applies - User wants a signals platform on the typed `DecisioningPlatform` surface - Specialism: `signal-marketplace` OR `signal-owned` - SDK package: `@adcp/sdk` **Wrong skill if:** - User wants to fork a worked adapter → `skills/build-signals-agent/` - User wants creative transforms → `skills/build-decisioning-creative-template/` - User wants to sell media inventory → `skills/build-seller-agent/` ## The whole shape (read this first) A signals platform implements two methods: - **`getSignals(req, ctx) → Promise<GetSignalsResponse>`** — sync catalog discovery. Buyer sends filters; you return the matching signals. No async envelope. …

How to install
mdr add adcontextprotocol/adcp-client/build-decisioning-signal-marketplace@sha256:da63f1c3630a9e1fThe line at the top of this page pins the label git:20261030.a66b6b6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
