Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install flux-image-prompting

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 applies Black Forest Labs' rules to build FLUX prompts: prompt structure, model choice, lighting, quoted text and hex colors. It can also prepare an image edit, a multi-reference style transfer and a JSON-described scene. You get prompts ready to paste into your generation tool.

Frequently asked questions

Does the skill generate the images?

No, it writes the prompts. For FLUX API calls it points to a neighboring skill (bfl-api) that is not included here.

Do the rules apply to every FLUX model?

The shared principles do. The flux2-models and flux1-models files detail what changes by family.
