Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install webpack-plugin-authoring

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 or reviews a webpack 5 plugin against 44 rules: hook choice and taps, the asset pipeline with emitAsset, cache dependencies, cleanup on shutdown, schema-utils validation and formatted errors. It draws on patterns from well-known plugins in the ecosystem. You get a plugin that behaves well in builds and in watch mode.
