Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install test-first-bug-fixing

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 reproduces the bug with a failing test, fixes the code until the test passes, then runs the whole suite to check for regressions. The test shows that the fix really solves the problem.
