Every n8n item carries two independent slots: $json for structured data and $binary for file bytes. They travel side by side through the workflow. File contents — the actual PDF, image, or zip — live in $binary, never in $json. Get that split wrong and you read an empty field, lose a file mid-flow, or hand an AI agent a tool input it can't use.
N8n Binary And Data is a community-contributed Claude Code skill in the automation sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/n8n-binary-and-data/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when working with files, images, PDFs, attachments, uploads or downloads, base64, vision/multimodal input, or when an AI agent needs a file as tool input or output — and whenever the user mentions $binary, binaryPropertyName, "read the PDF", "attach the file", "send the image", Merge losing binary, or a CDN for chat images. Covers the $binary vs $json split, reading/writing binary, keeping binary alive across transforms with Merge, the agent-tool binary boundary, and the CDN/URL requirement for chat surfaces.
The N8n Binary And Data Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
