Argus is a fast, native macOS editor built for Claude Code. See which files the agent touched, exactly what changed, and why it made each change. Then accept or revert each one.
Agents write code fast. Argus helps you read it just as fast and catch the mistakes before they ship.
A sidebar lists every file the agent changed, with line counts, edit counts and git status. Your own changes are listed separately.
Each edit carries Claude's own explanation and the prompt that led to it, inline and in a "Why it changed" panel.
Act on one hunk at a time or a whole file at once. Leave review comments and send them back to the agent.
Argus flags hardcoded secrets, disabled checks and new TODOs, so the risky lines stand out.
Step through a session prompt by prompt. Undo everything since a prompt, or follow the agent live as it works.
Written in Rust and GPU-rendered. Opens in a blink and stays smooth on large diffs.
The timeline lists each of the agent's edits in order, next to the prompt that caused it. Click an edit to jump to it. Click a prompt to see everything that has changed since you sent it.
- total += prices[sku] * *qty as f64;

An API key pasted into source, an #[allow] that hides a warning, a "TODO: fix later". Argus points them out before they reach a commit.
When something needs fixing, fix it right there. You don't need to switch apps.
