Subs

Streaming panels for every Claude Code sub-agent.
Stop guessing what your agents are doing. Watch them work in real time.

To all the people who hate working in the terminal.
To all the people who love working with Claude Code.
To all the people frustrated from getting lost tracking sub-agents.
This one is for you.

Subs cracks open the black box. Every sub-agent gets its own real-time panel, streaming tool calls, reasoning, and results as they happen.

Quick Start

1. Install from the VS Code Marketplace or run ext install OmryHazak.subs
2. Open a Claude Code session in VS Code
3. When a sub-agent spawns, its panel appears automatically

That's it. No configuration needed.

Features

• Auto-detection -- new sub-agent panels open instantly, no commands needed
• Streaming output -- tool calls, assistant text, and results appear in real time
• Completion detection -- done agents get a [Done] banner with the final result highlighted
• Token stats -- input/output tokens, cache hits, elapsed time, model name
• Parent session -- see which conversation spawned each sub-agent
• Auto-scroll -- follows output as it streams; freezes when you scroll up

Install

Search for Subs in VS Code extensions, or:

ext install OmryHazak.subs

git clone https://github.com/omryhazak/subs.git
ln -s "$(pwd)/subs" ~/.vscode/extensions/subs

Commands

The extension auto-starts on launch -- you shouldn't need these.

How It Works

Claude Code writes sub-agent transcripts as JSONL files in a temp directory. Subs watches for new .output files, opens a webview panel for each one, and incrementally parses new bytes every 400ms. When no new data appears for 5 seconds, the agent is marked as done.

Up to 20 concurrent panels. All file I/O is async. Nonce-based CSP. No innerHTML.
