prompt-engineer skillA

prompt-engineer is agent-read markdown (skill) from zacklecon/claude-skills: Use when designing prompts for LLMs, optimizing model performance, building evaluation frameworks, or implementing advanced prompting techniques like chain-of-thought, few-shot learning, or structured outputs..

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 zacklecon/claude-skills/prompt-engineer@v1.0.0
Exact content
mdr add zacklecon/claude-skills/prompt-engineer@sha256:4725e9bc5a4b3133

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.
