Login policy

Gravity drives the coding agents you already use. It never uses your AI login itself.

• Gravity never reads, copies, stores or relays a Claude, ChatGPT/Codex or Gemini login token or credentials file.
• Gravity never sends model requests with a subscription login. Only the vendor's own, unmodified CLI does, on your device.
• You sign in through the vendor's own flow on your own device (for Claude Code: run claude, then /login).
• gravity doctor asks the CLI whether it is signed in (claude auth status) and shows only signed in or not.
• Plan usage comes from Claude Code's own status line (percent used and reset time), never from a token.
• For CI and business use, the vendor's API keys (Console, Bedrock, Vertex) are the documented path, set in the vendor CLI.
• Gemini CLI with a Google login is not supported with Gravity: Google's terms do not allow it.

A CI check fails the build when Gravity code reads a credentials file or a login token variable.
