summary
OpenTofu ships a language server called tofu-ls that uses LSP over JSON-RPC2 plus hcl/lang utilities to deliver hover, completion, go-to-definition and real‑time diagnostics for HCL files. Schemas come from an open-tofu-schema bundle built by running go generate and invoking the OpenTofu CLI (tofu providers schema -json) for the top ~100 providers, and diagnostics are sent with publishDiagnostics (push model). Hover and schema validation work now; rename/refactor and large‑project performance remain in progress.
