Lockbox skills and plugin

Send API keys and private files to someone else's agent, end-to-end encrypted. lockbox.run

This repo holds the agent-facing parts of Lockbox: the lockbox skill and a plugin bundle for Claude Code, Codex and Cursor. The skill teaches your coding agent to use the lockbox CLI (npm i -g @opslane/lockbox) so keys go from one .env to another without being printed or pasted into chat.

Install

Any agent that reads skills (via skills.sh):

Terminal
npx skills add opslane/lockbox-skills

Claude Code:

Terminal
claude plugin marketplace add opslane/lockbox-skills
claude plugin install lockbox@opslane

Claude.ai and ChatGPT: add https://lockbox.run/mcp as a connector. The Lockbox panel opens in the chat.

Then install the CLI and sign in:

Terminal
npm i -g @opslane/lockbox
lockbox login you@company.com
