+// SkillDirs, and ProjectMemoryFile read a.workDir without holding
+// a.mu, while SetWorkDir writes a.workDir under the lock. Run with
+// -race to detect the data race; with the production fix the
+// detector stays quiet.
+//
+// claudecode is the primary agent and exposes the most readers of
+// the workDir field across the project, so the cumulative impact of
+// this race is the largest of any agent.
