Syntax — .rocky TextMate grammar + semantic tokens, plus code snippets for every DSL construct (from, where, group, derive, select, join, sort, match, window).
Activity bar sidebar — Get Started, Extension Info, Models, Runs, Sources, and Help panels. Workspaces without a rocky.toml show orientation and one-click actions for Initialize Project, Try Playground, and Open Documentation instead of CLI errors.
Lineage view — Rocky: Show Model Lineage renders the column-level DAG as an interactive graph.
AI generate — Rocky: Generate Model from Intent creates a model from a natural language description using the Rocky AI intent layer.
Status bar — LSP server status and live error count.
Open the Extensions view (Ctrl+Shift+X / Cmd+Shift+X).
Search for Rocky.
Install and reload.
The extension spawns rocky lsp on startup and attaches it as the language server for .rocky files.
