Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install bun-build-time-macros

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 a macro file, imports it with the macro type attribute, and has the value computed during bundling. It covers inlining environment variables, Git information, file embedding and code generation. You get a bundle in which those values are already fixed.
