agent-tool-builder skillA

agent-tool-builder is agent-read markdown (skill) from hybridlabor-api/bdb-dev-optimized-agent-skills: Tools are how AI agents interact with the world. A well-designed tool is the difference between an agent that works and one that hallucinates, fails silently, or costs 10x more tokens than necessary. This skill covers tool design from schema to error handling..

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 hybridlabor-api/bdb-dev-optimized-agent-skills/agent-tool-builder@sha256:7e9795b8092a01ae

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.
