Build a context lake

A context lake is Port's data model once it stops being a flat catalog and becomes a connected graph: blueprints related to each other, with mirror and aggregation properties, descriptions, and relation titles precise enough that an AI agent can traverse it and act, not just browse it. This skill designs that model. For the JSON mechanics of any single blueprint, property, or relation, use port-blueprints; this skill is the layer above that: what to build, in what order, and why.

Prerequisites

• Go over the port-getting-started skill first if this is your first time working with Port, it covers signing up and connecting Port's MCP server.
• If Port's MCP server is connected, this skill can use it to check what already exists (list_blueprints) and apply the resulting blueprint, relation, and property changes directly (upsert_blueprint), rather than just handing you JSON to apply yourself. Search search_port_knowledge_sources for anything this skill doesn't cover.
