Language Servers

Axon uses language servers for real project intelligence. Monaco can tokenize and edit text, but the language server understands imports, dependencies, symbols, project configuration, diagnostics, rename, references, definitions, and code actions.

Root Rule

Open the folder that owns the project metadata. Most weak language-server behavior comes from opening a nested folder instead of the root that owns package.json, tsconfig.json, go.mod, Cargo.toml, pyproject.toml, composer.json, .sln, pom.xml, build.gradle, or compile_commands.json.
