What it does

“Load immediately after an Agent intent. Then call build-agent with the user's request after any required orchestrator-owned prerequisites are ready. Agent Builder owns Agent setup and implementation questions. Governs prerequisite creation, faithful handoff, targeting, testing, and publishing. Use directly for routine Agent follow-ups; rerun intent-recognition only when the requested artifact is no longer clear.”
The author's description, from SKILL.md

Generated summary from the skill's own text

Agent Builder orchestrates the creation, modification, testing, and publishing of n8n Agents. It routes user requests to the embedded agent configuration tool, manages prerequisite workflows and data tables, and ensures faithful handoff of requirements without inventing implementation details.

When to use it

  • User asks to create, modify, test, or publish an Agent
  • Building an Agent after intent recognition confirms agent-anchored design
  • Adding capabilities, channels, or tools to an existing Agent
  • Creating prerequisite workflows or data tables for Agent use

When not to

  • User only wants to read, explain, or inspect existing Agent configurations
  • Request targets an unsupported chat channel with no alternative chosen
  • Routine edits better handled through direct Agent Builder interaction
