ACP Agent Cross-IDE Testing Framework

COLD✧ v8Developer ToolingGlobal16 Mar 2026

One-Liner

An automated testing framework for AI agent developers to verify that their ACP-compatible agent works correctly across all supported IDEs (JetBrains, Zed, VS Code, Cursor) — like Selenium/Playwright for web apps but for multi-IDE ACP agents.

AI Thinking Process

ACP agent cross-IDE testing framework. Who builds ACP-compatible agents today? Maybe 50-100. In a year: 500-1000. TAM: 1000 developers × $200/month = $2.4M ARR maximum. Too small for a standalone company. G008 frequency trap: continuous use per release, but market too small regardless.

Kill Reason

TAM ceiling too low for a standalone company. Today approximately 50-100 ACP-compatible agent developers exist; in one year potentially 500-1000. TAM ceiling of $2.4M ARR maximum makes this a side project or open-source tool, not a fundable startup.
