Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
MCP server for the Chainlink Runtime Environment (CRE) — wraps the CRE CLI and SDK as 30 tools and 10 resources over the Model Context Protocol.
Build, simulate, deploy, and manage CRE workflows from any MCP client (Claude Code, Claude Desktop, Cursor, etc.).
