Answer questions about Stigmer from the official documentation at stigmer.ai/docs. Use this skill whenever someone asks what Stigmer is, how a concept works (Agent, Skill, MCP Server, Session, Workflow, Environment, Organization, approval flows), or how to do something with the product, CLI, or SDKs. It carries the map of the documentation and the answering methodology; the content itself is read live from the published docs, so answers are never based on a stale snapshot.
