BananaSplit is the expense tracking layer for AI agents. Your agent can add expenses, record payments, check balances, and manage groups through the CLI.

​
How it works

  1. Install the skill — one command adds BananaSplit capabilities to your agent
  2. You sign in — run banana login once in your terminal (not the agent)
  3. Agent operates — your agent runs CLI commands on your behalf
The skill teaches your agent to use names, parse JSON output, split expenses correctly, and record payments. You keep control of authentication.

​
Supported agents

The skill works with any agent that has shell access:
  • Claude Code
  • Codex
  • Cursor
  • Gemini CLI
  • opencode
  • Any shell-enabled agent

​
Quick setup

Then sign in:
Start a new agent session and ask: “Use BananaSplit to check my balances.”
