Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and does disclose key side effects: automatic next ID assignment, ledger persistence, and syncing workflow_notes.md. It still omits permission requirements, duplicate handling, and reversibility, which matter for a write tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
