What

Task list documentation now recommends working on tasks in ID order (lowest first) when multiple tasks are available.

Details
  • New .highwatermark file for tracking task ID generation
  • Documentation updated to say "Prefer working on tasks in ID order (lowest ID first)"
  • Helps teams coordinate work more predictably
  • Part of the teammate workflow system
Evidence

Co3 = ".highwatermark" at line 155744 (highwatermark constant), string literal "Prefer working on tasks in ID order" in TaskList tool description

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
