flux2-klein-prompting

Solid

Expert prompt engineering for FLUX.2 [klein] image generation and editing model. Use this skill whenever the user wants to create prompts for FLUX.2 [klein], generate images, edit photos with the klein model, work with multi-reference image editing, or needs templates for T2I/I2I tasks. Trigger for any mention of: FLUX.2, flux klein, BFL API, image editing prompts, text-to-image prompts for FLUX, product mockups, poster generation, UI mockups, sticker packs, character design, seamless textures, or any request to write/improve/translate prompts for FLUX-family models. Also trigger when user asks about guidance_scale, inference steps, distilled vs base modes, or multi-reference workflows. Do NOT use for training a FLUX.2 Klein / Qwen-Edit LoRA (use flux2-lora-training), nor for reconstructing a prompt FROM an existing source image (use forensic-prompt-compiler); this skill is for authoring generation/edit prompts only.

# FLUX.2 [klein] — Prompt Engineering Guide ## Core principle: prose, not tags Official BFL prompting guide requires **connected prose**, not keyword lists. Write: who/what is in the image, where, in what style, materials/light/camera, and — for editing — what must remain unchanged. --- ## Model variants quick reference | Axis | Options | Notes | |---|---|---| | Size | 4B / 9B | 9B better for complex instructions; 4B fastest | | Mode | Distilled / Base | Distilled = 4 steps, CFG≈1.0; Base = 50 steps, CFG≈4.0 | | License | 4B Apache-2.0 / 9B Non-Commercial | Check before commercial use | | Task | T2I / Edit (I2I) / Multi-reference | Edit requires `input_image`; up to 4 ref images via API | **9B uses Qwen3 8B text embedder** → solid multilingual support (Russian works natively). --- ## Prompt structure ### T2I (text-to-image) 1. **Subject** — who/what, key attributes 2. **Scene/context** — where, time of day, surroundings 3. **Composition** — framing, angle, background 4. **Light/materials** — source, softness, reflections, texture 5. **Style/genre** — photorealism, illustration, catalog, poster, UI 6. **Text in image** (if needed) — exact string in quotes + position/font ### Edit (I2I, no mask) 1. **Base anchor** — "This exact image but…" 2. **What to change** — object / background / text / color / material 3. **What to preserve** — face, lighting, style, perspective, brand elements 4. **Multi-reference** — reference by "image 2 / image 3", keep prompt concise --- ...

forensic-prompt-compiler

Forensic image-to-prompt compiler for image generation models. Use this skill whenever the user wants to: convert/describe an existing image into a generation prompt, reconstruct a scene as a prompt, generate prompts from reference images for AI image tools (Midjourney, FLUX, Stable Diffusion, DALL-E, or any diffusion model), write prompts that preserve exact visual properties of a source image, or needs precise control over identity-safe subject description, geometry lock, lighting reconstruction, color anchoring, or handler-based special cases (floating scenes, collages, close-ups, jewelry, garments, surreal elements). Also trigger for requests involving: image editing prompts, reference-driven generation, pose description, camera angle locking, fabric/material description, or any "turn this image into a prompt" task. Do NOT use for composing prompts from scratch with no source image (use flux2-klein-prompting), nor for training a LoRA on edit pairs (use flux2-lora-training); this skill reconstructs a promp

flux

The FLUX craft skill (Black Forest Labs) — generate and edit on-brand images with the right variant and license. Use when someone wants to generate images with FLUX/FLUX.2/Kontext, edit a generated image, keep a character or product consistent across a campaign, render legible text in images, get brand-exact colors, pick between FLUX variants, or asks if their FLUX use is commercially licensed. Uses the PIXEL framework. Reads image-prompt + brand-profile + design-and-templates first. The agent writes prompts/edit instructions and can call the API where connected; the HUMAN judges every image; WoopSocial publishes. License spine: [dev] outputs are commercial-OK but self-hosting for a commercial service needs a paid BFL tier; Apache-2.0 paths are [schnell]/[klein] 4B. Never use unpermitted likeness, clone trade dress, strip provenance, or invent stats. Distinct from image-prompt, ideogram/nano-banana/Midjourney (sibling tools), ai-image-editing (the edit router this feeds), and canva.
