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.
