**Read what your agent wrote - before you say LGTM.**

A terminal diff reviewer for agentic coding. It runs in a pane beside your agent, shows what changed as it changes, and lets you point at exact lines when you reply.

**You keep your editor.** `hjkl`, `w b e`, `f t F T`, `/` and `n`, `V` to select, `zz` to centre - the motions already in your fingers, now pointed at the agent's work.

• A pane with your agent and tmux panes inside a window

• Side-by-side diff view

**Status: pre-alpha**, and used daily by its author.

It began a long time ago as a Go tool for reading diffs in a terminal. This is a rewrite in Zig, rebuilt around a coding agent rather than a person: the diff re-renders as the agent writes, references go straight to its input, and comments follow the code when it rewrites the file underneath them. The loop works end to end; the numbers below are measured, not estimated.

Why

Reviewing an agent is not reviewing a person: more code, arriving faster, with no prior about where the risk is. Without this, the loop goes - the agent edits six files, you scroll `git diff` in a pager, you spot something at `src/auth.zig:47`, and you **retype** that path into the chat. `lgtm` removes the retyping.

Install

**macOS**, from the tap:

brew install kunkka19xx/tap/lgtm

**Linux**, any distribution - the binary is static, so the distro doesn't matter. (Also macOS):

curl -fsSL https://raw.github
