# Code Review: Step 3 fix the client / tool

Result: approved.

No blocking findings. The implementation matches the live-probe result and the approved Step 3 plan: `feel` is no longer advertised or accepted by `update_wellness`, tool input containing `feel` is rejected before profile lookup / writer invocation with the explicit public error, and the intervals client rejects `WriteWellnessParams{Feel: ...}` before issuing an HTTP request. Read-side `feel` shaping remains intact through response fixtures/tests.

## Checks run

- `git diff 2b83585..HEAD --name-only`
- `git diff 2b83585..HEAD`
- Read changed files for context:
  - `internal/intervals/errors.go`
  - `internal/intervals/wellness.go`
  - `internal/intervals/wellness_test.go`
  - `internal/tools/update_wellness.go`
  - `internal/tools/update_wellness_test.go`
  - Step prompt/status/review files
- `go test ./internal/intervals ./internal/tools`
- `go test ./...`

## Notes

- The targeted and full unit suites pass locally.
- Step 4 still needs the requested build/lint/race/live re-validation and any documentation/changelog work remains in later task steps.
