What it does
Flux Image Best Practices is an agent skill from black-forest-labs/skills. Comprehensive guide for BFL FLUX image generation models. Covers prompting, T2I, I2I, structured JSON, hex colors, typography, multi-reference editing, and model-specific best practices for FLUX.2 and FLUX.1 families.
Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files (for example `AGENTS.md`, `metadata.json` and `rules/_sections.md`).
It sits in Media & Creative, covering Image generation and Typography. The repository describes itself as: Official agent skills from Black Forest Labs for FLUX image and video generation — prompting guides and API integration patterns for Claude Code, Codex, and any… The licence is MIT.
When your agent uses it
- Tasks that involve Image generation
- Tasks that involve Typography
Example prompts
- “/flux-image-best-practices”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- NO negative prompts - FLUX does not support negative prompts; describe what you want
- Be specific - Vague prompts produce mediocre results
- Use natural language - Prose/narrative style works best
- Specify lighting - Lighting has the biggest impact on quality
- Quote text - Use "quoted text" for typography rendering
- Hex colors - Use #RRGGBB format with color description
What it can do on your machine
Read from SKILL.md and the folder at commit 8907d51. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Flux Image Best Practices loads about 983 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 264 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

FLUX Best Practices
Use this skill when generating prompts for any BFL FLUX model to ensure optimal image quality and accurate prompt interpretation.
When to Use
- Creating prompts for FLUX.2 or FLUX.1 models
- Text-to-image (T2I) generation
- Image-to-image (I2I) editing with FLUX.2 models
- Structured scene generation with JSON
- Typography and text rendering
- Multi-reference style transfer
- Color-accurate brand generations
Quick Reference
Prompt Structure Formula
[Subject] + [Action/Pose] + [Style/Medium] + [Context/Setting] + [Lighting] + [Camera/Technical]Model Selection
| Use Case | Recommended Model | Notes |
|---|---|---|
| Fastest generation | FLUX.2 [klein] | 4B or 9B, sub-second |
| Highest quality | FLUX.2 [max] | Best detail, grounding search |
| Production balanced | FLUX.2 [pro] | Quality + speed |
| Typography/text | FLUX.2 [flex] | Best text rendering |
| Local/development | FLUX.2 [dev] | Open weights |
| Image editing | FLUX.2 [pro/max] | Pass image URL directly to input_image |
| Inpainting | FLUX.1 Fill | Object removal/completion |
| Context editing | FLUX.1 Kontext | Older model, prefer FLUX.2 |
Critical Rules
- NO negative prompts - FLUX does not support negative prompts; describe what you want
- Be specific - Vague prompts produce mediocre results
- Use natural language - Prose/narrative style works best
- Specify lighting - Lighting has the biggest impact on quality
- Quote text - Use "quoted text" for typography rendering
- Hex colors - Use #RRGGBB format with color description
