codex-utils skillA

codex-utils is agent-read markdown (skill) from bjornmelin/dev-skills: Use built-in Codex coordination, retrieval, and utility tools effectively during live sessions. Trigger when work benefits from maintaining a step plan, asking the user 1-3 short multiple-choice questions before risky edits, inspecting a local image from disk, searching or browsing the web for current or source-backed information, discovering additional MCP tools or plugins, or running independent developer-tool calls in parallel..

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

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.
