Ivan Leo uses Antigravity to build a bank transaction-export CLI

• Antigravity is retrieving Ivan Leo's bank transactions, according to his report.
• Bank-site inspection produces a command-line script, he explains.
• Authentication uses a custom browser extension and 1Password, according to his description.
• Plaid's lack of Singaporean bank support drove the workaround, he says.

Leo's broader target is an API for his financial accounts. He also says browser access can reach data missing from an API.

The interesting artifact is the generated CLI: Leo says models can turn their exploration into deterministic scripts. He describes three steps:

1. He points Antigravity at a bank website.
2. The agent inspects the website through browser use.
3. It writes a script exposed as a CLI.

The posts describe transaction retrieval and export as the immediate task. They do not specify an export schema, refresh schedule, or recovery behavior when the bank website changes.

Leo built a browser extension that he says mimics the Codex extension, and uses browser automation with 1Password. He describes giving Antigravity access to all his bank accounts while setting up finance automations.

Google's built-in browser subagent connects through Chrome DevTools MCP. Its Chrome-profile documentation says that subagent shares the user's existing cookies and sign-ins; those docs describe Google's browser connection, while Leo reports using his own extension.

Google also documents separate settings for custom JavaScript execution and URL allow/deny rules. Leo's posts do not describe the approval settings used for his banking workflow.

Leo initially considered connecting his accounts through Plaid. He says Singaporean banks are unsupported, making browser access a better fit for his accounts.

Plaid's country-and-product matrix does not list Singapore for Transactions. The products listed as globally available are Identity Verification and Monitor, which serve identity verification and compliance rather than transaction retrieval.

Leo also says the agent he calls Argon handled wire details “start to end” through computer use in Antigravity because he did not want to enter them himself. His description does not specify the authorization or settlement steps.
