Hey PH gang 👋 PD here with Delta - a code review / agentic dev app that walks you through your agent-written code. Like a lot of you, I'm shipping so much now that just reading the diff and figuring out what's going on eats my day. Delta turns your branch into a walkthrough: an easy-to-follow outline with the relevant diffs inline. It surfaces what matters and tucks away the noise (lockfiles, schema dumps, generated code), and drops in review callouts on the things worth a closer look. A few other highlights: 🤖 Bring your own agents. Delta works with your Claude / Codex subscription 👨💻 Built-in terminal and console to run your agents right where you review 🌐 Hooks and scripts you can run per worktree / branch 🎨 A bunch of themes. Who doesn't love a little color. I've been using it daily for over a month and genuinely love it. It's FREE, so give it a shot and let me know what you think!
