tool-design skillA
tool-design is agent-read markdown (skill) from mjunaidca/mjs-agent-skills: Design tools that agents can use effectively. Use when creating new tools for agents, debugging tool-related failures, or optimizing existing tool sets..
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 mjunaidca/mjs-agent-skills/tool-design@git:20251222.04068a4mdr add mjunaidca/mjs-agent-skills/tool-design@sha256:5f6422ff0397b8a1Pin 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.
