These Claude Code Mods Are ACTUALLY Useful: Filetree, Replay Theater, Blast Radius & More

Join the membership (members-only videos on every level from Bronze up): https://www.youtube.com/@AICodeKing/join In this video, I'll show you seven Claude Code mods that are actually useful, with the installation and a practical walkthrough for each one on a small task manager project. We start with Filetree, a file browser right next to the conversation, and Replay Theater, which lets you step through the edits Claude just made. Then we try Blast Radius on a dummy build folder, use Collision Guard with two chats editing the same file, and watch three parallel agents in Agent Flow. Finally, we save a reviewed project rule with Reflect and look at what Cache Tax can and can't do for your costs. -- Key Takeaways: ⚙️ Mods need Claude Code 2.1.287 or newer, load by default, and run with your permissions, so check the publisher before installing. 📁 Filetree puts a project browser beside the conversation and shows which files Claude reads and changes, without a separate model request. 🎬 Replay Theater steps through the last turn's edit requests, but it's a session view, so confirm the result with git diff and your tests. ⚠️ Blast Radius holds certain risky Bash commands like rm -rf and shows what they would affect before you choose Proceed or Cancel. 🛡️ It only recognizes particular Bash patterns, so keep normal permissions in place and still read the actual command. 👥 Collision Guard asks before a second chat edits a file another open chat changed recently, with a 30-minute lookback by default. 🔍 Agent Flow shows each delegated agent's state, current tool and elapsed time, but the agents themselves still use your normal usage. 🧠 Reflect turns a correction into a rule you review, and saves it to the right CLAUDE.md scope only after you approve it. 💸 Cache Tax can ping to keep a one-hour cache warm, but the pings cost tokens and only help if you actually come back to the conversation. ✅ You don't need all seven: start with the problem you actually have, test the mod on a small project, and disable what doesn't earn its place.
