Frequently Asked Questions

FAQPage Schema
How to install Earl?โ–ผ

Run `npx skills add mathematic-inc/earl --all -g -y` in your terminal to install all skills in this suite globally.

How does Earl keep API keys safe?โ–ผ

Secrets are stored in the OS keychain and never appear in tool arguments, descriptions, or output. The model only supplies parameter values while humans write and review the request templates.

Can Earl replace raw curl and gh CLI calls?โ–ผ

Yes. The migrate-to-earl skill scans your codebase for raw curl, gh, stripe-cli, and similar calls, then replaces them with reviewed Earl templates one provider at a time.

Does Earl work with Claude Code and Cursor?โ–ผ

Yes. Earl runs as an MCP server and the setup skill writes the correct config for Claude Code, Claude Desktop, Cursor, and Windsurf automatically.

How do I stop my agent from bypassing Earl?โ–ผ

The secure-agent skill adds platform-level deniedTools rules and network egress allowlists, making Earl's security enforceable rather than advisory.
