Quick-reference mental model for the Tesseron TypeScript SDK — core abstractions (app, action, resource, handler, ActionContext, transport, session, gateway), canonical imports per consumer package (@tesseron/web, /server, /react, /core, /mcp), and the minimum-viable-app template. Load when the user is starting Tesseron work, wiring a first action or resource, deciding which consumer package to import, writing a handler for the first time, or orienting on how the pieces fit together. Triggers on code that imports from @tesseron/*, on calls to tesseron.action(...), tesseron.resource(...), tesseron.connect(...), useTesseronAction, useTesseronResource, or useTesseronConnection, and on broad questions like "what is Tesseron", "how do actions work", "where do I start". For authoritative specs — exact wire format, error code tables, handshake and resume shapes, full protocol behaviour — prefer the tesseron-docs skill, which queries the live @tesseron/docs-mcp server. This skill is the cheat sheet; tesseron-docs is the manual.
