# curated_ep29_flux_dev_replace_complex_background

Curated workflow skill generated from `EP29 Flux Dev Replace Complex Background.json`.

## Capability Family

- `editing_restyle`

## Inputs

- Optional runtime overrides supported by `run(...)`:
  - `prompt`
  - `negative_prompt`
  - `width`, `height`
  - `seed`, `steps`, `cfg`
  - `sampler_name`, `scheduler`, `denoise`
  - `server`, `headers`, `api_prefix`

## Outputs

- Returns JSON with:
  - `status`
  - `prompt_id`
  - `output_images` (includes image/video entries reported by Comfy history)

## Model Requirements

- `vae`: `ae.safetensors` -> `models/vae`
- `controlnet`: `flux-dev-controlnet-union.safetensors` -> `models/controlnet`
- `diffusion_model`: `flux1-dev-Q8_0.gguf` -> `models/diffusion_models`
- `clip`: `t5-v1_1-xxl-encoder-Q8_0.gguf` -> `models/clip`
