Empryo's code intelligence runs a full LSP layer. It ships a Mason-backed installer so you can add servers for any language from the TUI without touching your Neovim config.

Commands

/lsp                open the LSP manager (install, enable, disable)
/lsp install        search and install servers (Mason registry, 576+ packages)
/lsp status         attached servers with PID, language, capabilities
/lsp restart        restart all, or filter by language

What the agent uses

Every code intelligence operation tries LSP first:

Go-to-definition
Find references
Workspace-wide rename
Diagnostics (errors, warnings, info)
Code actions (quick fixes, refactors)
Call hierarchy (incoming and outgoing)
Type hierarchy (super and subtypes)
Hover and type info
Format document and format range

No manual setup required. The agent picks the right tool automatically.

Dual backend

Empryo runs LSP in two modes, whichever is available:

Mode	When
Neovim bridge	Editor panel open. Routes through your running Neovim LSP clients. Zero warm-up cost.
Standalone	Editor panel closed, or Neovim not installed. Empryo spawns LSP servers directly into `~/.empryo/lsp-servers/`.

Both cover the same capabilities. Standalone servers stay warm as hot standby even when Neovim is open.

Supported languages

Typical LSP coverage (any Mason package works): TypeScript, JavaScript, Python, Go, Rust, Java, Kotlin, Scala, C#, Swift, Dart, Elixir, OCaml, Lua, C, C++, Ruby, PHP, Zig, Bash, CSS, HTML, JSON, TOML, YAML, Dockerfile, Vue.

Tree-sitter detection adds ReScript, Solidity, TLA+, Emacs Lisp, Objective-C, Nix, HCL/Terraform, Bazel/Starlark, Jsonnet, Makefile, GraphQL, Protobuf, SQL, Markdown, MDX, XML, and more.

For anything LSP doesn't cover, the intelligence router falls through to ts-morph (TypeScript/JavaScript AST), tree-sitter, and regex.

Mason installer

/lsp install opens a fuzzy-search browser over Mason's registry. Pick a package, press enter, Empryo installs it:

npm packages to ~/.empryo/lsp-servers/node_modules/
pypi via pip3
cargo via cargo install
golang via go install
github releases downloaded and extracted

Already installed locally or via your Neovim's Mason? Empryo picks them up from the existing paths.

Check health

/diagnose runs a full check: tree-sitter, LSP readiness, semantic indexing, Genome status. Use it when something doesn't feel right.
