npx skills add runapi-ai/flux-kontext -gInstall the Flux Kontext skill for me: 1. Clone https://github.com/runapi-ai/flux-kontext 2. Copy the skills/flux-kontext/ directory into your user-level skills directory (e.g. ~/.claude/skills/ for Claude Code, ~/.codex/skills/ for Codex). 3. Verify that SKILL.md is present. 4. Confirm the install path when done.
Flux Kontext is Black Forest Labs' in-context image editing model that applies targeted edits while preserving style, character identity, and scene composition. It excels at style transfer and maintaining visual consistency.
