Claude Code reads this file automatically. It is the operating contract for building n8n workflows in this repository. A build harness. Workflow JSON under workflows/<env>/ is the source of truth; the n8n canvas is a view of it. Both MCP servers run n8n-mcp, pinned in package.json and installed into nodemodules/. It is the source of every node schema, validator, and template here, and it is why you configure from the live schema rather than from memory. n8n-docs carries no credentials…

CLAUDE.md vs AGENTS.md

About CLAUDE.md

What is CLAUDE.md?

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.

Where does it go?

At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.

What should it contain?

Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.

CLAUDE.md or AGENTS.md?

Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
