Tracon

Tracon is an air traffic control monitor for parallel Claude Code subagents that spots stuck agents and file conflicts.

Tracon acts as air traffic control for parallel Claude Code subagents, providing a live terminal and browser monitor that tracks agent activity. It reads transcripts directly from disk without modifying your repository, requiring no setup, accounts, or configuration. It spots stuck agents, permission prompts, loops, and worktree file conflicts headed for your merge. The tool includes an optional LLM judge to check each busy agent against its brief, a timeline scrubber, and a files heatmap. It is designed for developers running complex multi-agent coding sessions on supported operating systems.
