battlecard-system skillA
battlecard-system is agent-read markdown (skill) from gtmagents/gtm-agents: Use to standardize competitive positioning, objection handling, and talk.
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 gtmagents/gtm-agents/battlecard-system@git:20251119.8c446bfmdr add gtmagents/gtm-agents/battlecard-system@sha256:610b6f783b8220c1Pin 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.
