okhp3-custom-gpt-builder skillA

okhp3-custom-gpt-builder is agent-read markdown (skill) from okhp3/skillz: Build, audit, and improve OpenAI Custom GPTs with production-grade methodology. Use this skill when the user asks to create, configure, test, evaluate, audit, improve, troubleshoot, compare, document, or package a Custom GPT or reusable ChatGPT workflow. Also use it for GPT Builder instructions, knowledge files, Actions, Apps/connectors, GPT Store readiness, Gemini Gem comparison, Copilot declarative-agent comparison, or conversion between Custom GPTs and Agent Skills..

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 okhp3/skillz/okhp3-custom-gpt-builder@v1.3.0
Exact content
mdr add okhp3/skillz/okhp3-custom-gpt-builder@sha256:8f8a9b22e802a1ba

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.
