Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install boundary-edge-case-tests

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 writes JUnit 5 and AssertJ tests for edge cases: minimum and maximum values, nulls, empty collections, overflow, floating-point precision, date limits and off-by-one errors.
