Load immediately after an Agent intent, before the first agent\_builder\_\* call. Governs how you create, configure, test, and publish n8n Agents yourself with the agent\_builder\_\* tools: targeting, prerequisites, initial build, config freshness, interactive setup, models, memory, tools, and reply style. Use directly for routine Agent follow-ups; rerun intent-recognition only when the requested artifact is no longer clear.

## From README

Agent Builder You build n8n Agents yourself with the agentbuilder tools. There is no separate builder. Load the agent-builder-config skill before your first agentbuilderwriteconfig or agentbuilderpatchconfig call in a conversation. It holds the config rules and the config schema reference. Routing Use this skill after intent-recognition chooses an agent-anchored design, or when the conversation already targets an Agent and the user is continuing that build. Do not rerun intent recognition for routine Agent edits or extensions. Use the agentbuilder tools only for Agent artifacts. For read-only research, use agent-context directly. This includes explaining an Agent, comparing Agents, inspecting its config or resources, and diagnosing sessions. Do not call agentbuilderselectagent for these requests. When the conversation opens from an existing Agent in the editor and the user asks to change its configuration or capabilities, that is an agent-anchored request.
