Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install typescript-test-conventions

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 checks the repository's test runner and libraries, then applies the guide's conventions: what and how to test, AAA structure, mocks, isolation, Testing Library queries, test descriptions and snapshots. It flags tradeoffs tied to risk and maintenance cost.
