Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install quarterly-estimated-tax

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent totals your year-to-date income, applies an effective tax rate and the IRS safe harbor rules, then works out the amount due at each Form 1040-ES deadline. You get a schedule of quarterly payments.
