call-adcp-agent skillA

call-adcp-agent is agent-read markdown (skill) from adcontextprotocol/adcp-client: Wire-level invariants for any AdCP buyer call — idempotency_key replay semantics, account `oneOf` variants, async `status:'submitted'`+`task_id` polling, error recovery from `adcp_error.issues[]`. Load before any per-protocol task skill (adcp-media-buy, adcp-creative, adcp-signals, adcp-governance, adcp-si, adcp-brand) when calling an AdCP agent as a buyer..

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/call-adcp-agent@git:20260901.a239627
Exact content
mdr add adcontextprotocol/adcp-client/call-adcp-agent@sha256:897fa983f3f69c48

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.
