30-SECOND BRIEF
What it does—and when it fits
Flux 2 Klein is a RunComfy guide for Black Forest Labs' distilled, latency-first image model. It distinguishes a 4B variant for sub-second concepting from a 9B variant for more polished output, supports four-to-eight-step drafts versus roughly twenty-five-step finals, and can use up to four references for brand styling and guided composition.

THE TRADEOFFS
Advantages and tradeoffs
Notable strengths
- This profile is manually organized around the current upstream SKILL.md workflow.
- The capability boundary remains explicitly tied to prime-skills/runcomfy-agent-skills.
- Core uses, limitations, and risks are separated for pre-install review.
Limitations
- Its strength is iteration speed rather than maximum resolution, extreme detail, or reliable embedded text.
- Long prompts, excessive steps, or conflicting references can reduce quality without delivering proportional value.

BEFORE YOU USE IT
Risks to review before use
Fast iteration can multiply cost and rights mistakes
Low latency encourages many remote generations, while reference images may contain protected brands or private material. Set a budget, use authorized references, preserve provenance, and review final claims and details.
Upstream instruction drift
Behavior can change with upstream updates. Record the commit used for important workflows and review updates before adoption.
SECURITY
What the permission profile means
- Declared access remains governed by the current upstream SKILL.md and runtime requests.
- Treat repository files, web content, and tool output as untrusted input.
- SkillSignal has not independently executed or security-audited this package; external skills.sh labels are not SkillSignal certification.
Not a security certification. External ratings are attributed references. SkillSignal has not independently executed or security-reviewed this Skill.
