Discover available tools, coordinate safe parallel reads, clarify decisions, inspect images, and verify current sources.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex Utils Use the lightest available tool that resolves the need. The current session's tool catalog, schemas, and restrictions are authoritative; never assume a tool name from another host or session exists. ## Coordination - Use a planning tool when available and useful for non-trivial work; otherwise keep a short checklist. Do not create a persistent goal unless requested. - Use the available user-input tool for optional clarification, following its current mode restrictions. Ask directly when explicit approval is required; a recommended or preselected option is not approval. - Inspect local images with the available image-viewing tool before editing or judging them. Use original detail only when necessary. ## Discovery and execution - Search the exposed tool catalog before declaring a capability missing. In Code Mode, filter `ALL_TOOLS` by name/description and call the matching `tools` method. Use tool search only when the session exposes it. - Match the actual schema before calling. Never print credentials, raw auth configuration, or secret-bearing subprocess arguments while inspecting tools. …

How to install
mdr add bjornmelin/dev-skills/codex-utils@sha256:e259ac3e79022919The line at the top of this page pins the label git:20261015.8ae5a79, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
