- Worth noticing
- The Item Tester traces supported conditions to a matched rule and style; unresolved inputs are explicitly marked unknown.
Field notes
The toolset spans starter-filter creation, syntax diagnostics, item matching, color previews, strictness references, and text diffs. The validator reports line-numbered errors and warnings, while the compare tool can export a JSON report of changed blocks. Its boundaries are explicit: starter data is not live economy pricing, the strictness slider does not inspect a player's filter, and unsupported item-test inputs remain unknown.
