From 5cfa7ccc8f4082db111bc0186c5fa3d44b767ad3 Mon Sep 17 00:00:00 2001 From: amankumarsingh77 Date: Tue, 28 Jul 2026 00:01:32 +0530 Subject: refactor(tools): declare concurrency in the tool definition serialized: true was applied in registry.ts, away from the tools it describes. Now a required concurrency field on each definition, with a test pinning the serialized set so the classes cannot drift. The lock check defaults to taking the mutex for any class that is not explicitly "parallel", so a definition that bypasses defineBrowserTool at runtime fails safe rather than racing on shared CDP state. The test script gains --conditions=import: pi-coding-agent publishes no "require" condition, so importing any tool definition from a CJS-loaded test could not resolve it.
