Which repository this server bound to, and how. Answers cheaply without starting the language server — use it first to confirm the server is pointed at the project you think it is.

Find a symbol by name anywhere in the project, resolved by the language server rather than by text search. Returns each match with its file and line.

Outline one file: every type, method, and field it declares, with line numbers. The API surface of the file without reading its body.

Find everything that references a symbol — the real call/usage sites the compiler sees, including dependency-injection registrations and interface implementations that a text search misses. Run this before renaming, changing a signature, or deleting.

The full source of one declaration, by name — a method, class or function — without reading the file it lives in. Use this instead of opening a file to look at a single member.

Compiler diagnostics for one file, from the already-running language server — errors and warnings in milliseconds, without a build. Run this after editing to confirm the change compiles.

Jump to where a symbol is defined, resolved by the language server.

What a symbol is: resolved type, signature and documentation, plus its declaration line. Answers 'what does this call do' without opening the file.

What breaks if this symbol changes: everything that references it, then everything that references those, to the given depth. Run before changing a signature or deleting anything.

Rename a symbol everywhere, using the compiler's own understanding rather than text replacement — so it renames the right things and leaves unrelated same-named symbols alone. Defaults to a dry run showing what would change.

Find the concrete implementations of an interface or abstract member, or the overrides of a virtual one. Answers 'what actually runs when this is called', which references alone cannot tell you.
