Event Horizon VS Code Extension Adds File Locking and Plan Coordination for Multiple AI Agents
Event Horizon is a VS Code extension that started as a visualization tool for Claude Code but has evolved to solve a practical problem: preventing multiple AI coding agents from breaking builds by editing the same files simultaneously.
Problem and Solution
The developer encountered issues when running Claude Code in one terminal and OpenCode in another, both editing the same project. One agent would overwrite the other's work, leading to broken builds that required hours to untangle.
Key Features
- File Locking: When one agent is writing to a file, others are hard-blocked from touching it. The blocked agent sees who holds the lock and works on something else instead, ensuring zero interleaved writes.
- Plan Coordination: Create a plan where agents claim tasks atomically, preventing two agents from working on the same thing. Dependencies are enforced, and a Kanban board updates live as work progresses.
- MCP Tools: Handle all coordination under the hood. Everything auto-registers when you connect an agent, requiring no manual configuration.
- Visualization: The original visualization remains, with file collisions now sparking lightning between planets. This provides an immediate visual indicator when agents are fighting over the same files.
Technical Details
