Work with macOS Keychain generic password items through bundled scripts. Use when Codex needs to check, read metadata, create, update, retrieve, reveal, or delete local credentials by `service + account` on macOS, especially as a thin credential-store wrapper inside another workflow.
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
# Mac Keychain Use this skill to operate on macOS Keychain generic password items. ## Scope - Support `exists`, `read-meta`, `set`, `update`, `read-secret`, `reveal-secret`, and `delete`. - Operate on generic password items only. - Stop if the request involves certificates, identities, private keys, or broad keychain administration. ## Runtime - Require `macOS`, `/usr/bin/security`, and `/bin/zsh`. - Use the bundled scripts for deterministic behavior. - Stop and explain the missing runtime dependency if the scripts cannot run as shipped. ## Operating Rules - Resolve the target with `service + account` before any write, delete, or secret read. - Default to the current user's `login` keychain. - Pass `--keychain` only when the target is not the default login keychain. - Keep caller attribution, approval prompts, and workflow policy in the caller. Do not model them inside this skill. - Keep the script interface narrow. Do not pass legacy caller-attribution or purpose flags. - Keep this skill thin. It should expose local Keychain operations, not orchestrate a larger secret-management workflow. ## Safety Model …

How to install
mdr add flc1125/skills/mac-keychain@sha256:1dc651107e87890aThe line at the top of this page pins the label git:20260405.bba781e, 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.
