# R012 Code Review — Step 4

Verdict: REVISE

## Findings

1. **`git diff --check` fails on committed review artifact whitespace.**
   `taskplane-tasks/TP-101-claude-desktop-mcpb-extension/.reviews/R011-code-step4.md:7` contains trailing whitespace, so `git diff 3cdc243..HEAD --check` exits non-zero. Please strip the trailing spaces so the step diff is clean. This is small, but it is currently the only failing verification I found in the Step 4 diff.

## Verification performed

- `git diff 3cdc243..HEAD --name-only`
- `git diff 3cdc243..HEAD`
- Read changed files for context: `CHANGELOG.md`, `STATUS.md`, `web/content/connect/claude-desktop.md`, and prior Step 4 review files.
- `git diff 3cdc243..HEAD --check` — failed on trailing whitespace in `.reviews/R011-code-step4.md`.
- `cd web && hugo` — passed with existing theme deprecation warnings.

## Notes

- The updated Claude Desktop docs make the `.mcpb` path primary, preserve the manual JSON/keychain fallback, and clearly keep API keys out of chat/manual JSON.
- The R011 validation note in `STATUS.md` now records a Claude Desktop-mediated `icuvisor_list_advanced_capabilities` call result, addressing the previous Step 4 validation gap.
