LSP Setup

Configure the right Language Server for a project so the lsp MCP tools (diagnostics, goto_definition, find_references, symbols, rename) actually work. This skill is an index: detect what a project needs, install the server, write the config, then verify with a real roundtrip.

The list of servers we ship as builtin is the source of truth in packages/lsp-tools-mcp/src/lsp/server-definitions.ts (BUILTIN_SERVERS + LSP_INSTALL_HINTS). The per-language references below mirror it.

PHASE 0 — LANGUAGE GATE (run first)

Identify the language from the file extension, then read the matching reference before installing or configuring anything.
