keys-keeper
Cross-platform (macOS + Windows + Linux) secrets manager skill: stores API keys, SSH keys, server creds, and domain info in the OS-native credential store (macOS Keychain / Windows Credential Manager / Linux Secret Service, encrypted-file fallback on headless servers) via the `keys` CLI. Agents architecturally cannot reveal plaintext (Sealed wrapper + env-gated reveal). First-class Claude Code skill; `keys init` emits equivalent rule files for Cursor, Aider, Codex CLI, and Cline.
