 ## 2. Recent Changes/Decisions
 
+- **GitHub Actions:** Added explicit `npm install -g pnpm` step to `validate`, `build`, and `publish-npm` jobs in `.github/workflows/publish.yml` to fix potential `pnpm` not found errors.
+
 - Removed `edit_file` tool and related files (`editFile.ts`, `editFileUtils.ts`, `editFile.test.ts`).
 - Added `apply_diff` tool (`applyDiff.ts`, `applyDiffUtils.ts`, `applyDiffSchema.ts`, `applyDiff.test.ts`).
 - Updated tool registration in `index.ts` and `handlers/index.ts`.
