We Built an Engine to Scan 1,270 Files in Minutes. **[Just Kotlin](https://daily.dev/sources/justkotlin)** · [@techsoneai](https://daily.dev/techsoneai) · 1 min read · 1 upvotes · 0 comments ## Summary An audit of a 1,270-file Kotlin Multiplatform project found 55 compile-breaking errors and 13,246 architectural warnings, including dead code, deprecated APIs, and scope leaks. Standard IDE batch inspections on the project took over 30 minutes and choked memory. The team built ComposeBridge, a tool that interfaces directly with the IDE's compiler PSI daemon for sub-50ms local diagnostics at zero AI token cost. It also syncs edits to physical hardware in real time and feeds compilation diagnostics back to local AI agents via MCP so they self-correct before a diff is reviewed. The core tools and MCP server are open-source. ## Content The hidden cost of AI coding agents isn't just the API bill—it's the silent technical debt left behind in production codebases. To test this, I ran an audit on a real-world **1,270-file Kotlin Multiplatform (KMP)** project. The findings: - **55 compile-breaking errors** - **13,246 architectural warnings** (dead code, deprecated APIs, scope leaks) Running standard IDE batch inspections on a project this large took over 30 minutes and choked memory. ### How We Solved It Locally Instead of relying on heavy cloud linters or sluggish Gradle tasks, we built **ComposeBridge**: 1. **Sub-50ms Local Diagnostics:** Interfacing directly with the IDE's compiler PSI daemon to audit AST changes instantly with **0 AI token cost**. 2. **Bi-directional Live Sync:** Edits reflect on physical hardware in real-time, bypassing emulator bloat. 3. **Hard-Gated Agent Feedback:** Feeding precise compilation diagnostics back to local AI agents (via MCP) so they self-correct before you ever review the diff. The core tools and MCP server are completely open-source. 👉 **GitHub:** https://github.com/JALAL591/compose-bridge 👉 **JetBrains Marketplace:** https://plugins.jetbrains.com/plugin/35226-composebridge Would love to hear how your teams handle AI code auditing and AST linting at scale!  ## Similar posts on daily.dev - [We Gave Agents IDE-Native Search Tools.
