Usage JSON

Domain: Skills System

Motivation

A small file (.usage.json) next to each skill that records usage statistics: times used, last used date, success rate.

debugging/.usage.json contains: {used_count: 42, last_used: 2026-08-03, success_rate: 0.88}. The curator reads this to decide if the skill is stale.

A mileage log in a car - it tracks total miles, last trip date, fuel efficiency. .usage.json tracks a skill usage stats the same way.
