This skill should be used when the user has an approved Design Spec and wants to build platform artifacts for their AI workflow. It prepares the workflow's context with the user, researches integration availability, generates platform-appropriate artifacts (skills, agents, configs, connectors), installs them, and reconciles what was built against the spec. Also use when the user says "continue my workflow" and the Workflow node shows Step 4 (Build) is next. This is Step 4 (Build) of the AI Workflow Framework. NOT for "build my knowledge graph": that is the building-knowledge-graph skill.
