Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install typescript-variable-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 examines declarations and application state, then applies the guide's rules: const by default, const assertions, literal unions instead of enums, state unions in place of boolean flags, and choosing between null and undefined. The final choice stays with you.
