# Code Review — Step 4: Implement the confusable-names check

Decision: **APPROVE**

## Findings

No blocking findings.

## Notes

- The previous event-prefix gap is fixed: `toolCluster` now assigns any `get_event*` tool to the event/calendar cluster while preserving `get_training_plan` as the explicit cross-domain alias.
- The checker uses the live registry catalog, extracts first description sentences with dotted-token handling, computes token Jaccard within multi-tool clusters, and emits actionable failure messages with both tool names, score, and first sentences.
- `CONTRIBUTING.md` documents the `0.58` threshold and the rewrite guidance.

## Verification run

- `go run ./scripts/check_confusable_names.go` — passed
- `go test ./...` — passed
- `make lint` — passed
