$ # what's inside

tree-sitter syntax — eight languages built in, thirty more one install away

language servers — your own — diagnostics, completion, go to definition, auto-import

git — stage, commit, sync, stash; diffs inline or side-by-side; merge conflicts resolved right in the buffer

review notes — left on lines, shared with an agent through review.json, replies read as threads

search — project-wide find and replace; a fuzzy picker that reads file.ts:42 straight from a stack trace

views — markdown rendered in place — mermaid diagrams included — and images

folding — from indentation, so it works even where no grammar does

vim mode — plus custom keybindings and themes that follow the OS appearance

extensions — JSON manifests, not code — installing one runs nothing
