Summary of Changes

Hello @Nixxx19, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on code quality and maintainability by consolidating duplicate import statements across several files in the sdk and test-utils packages. This is the first part of a larger effort to ensure compliance with the import/no-duplicates ESLint rule, resulting in cleaner and more consistent import declarations without altering any functional behavior of the application.

Highlights

• Import Consolidation in packages/sdk: Merged duplicate import statements from node:path in test files (agent.integration.test.ts, skills.integration.test.ts, tool.integration.test.ts) and from @google/gemini-cli-core in shell.ts to comply with ESLint rules.
• Import Consolidation in packages/test-utils: Consolidated duplicate import statements from node:fs in test-rig.ts.
• ESLint Compliance: This PR addresses the import/no-duplicates ESLint rule by ensuring all imports from the same module are grouped into a single statement.

  • Removed a redundant import for dirname from node:path.
  • Updated the __dirname assignment to use the already imported path module.
