When to choose Gemini 3.8 Flash
1
Multi-step agent plan
Decompose a long-running goal into checkpoints, tools, verification, and recovery steps.
Prompt starter
Plan and execute [goal] in checkpoints. Before each action state the evidence needed; after each action verify the result and update the remaining plan. Stop on irreversible ambiguity.
2
Repository-scale code review
Trace behavior across files, identify failure paths, and propose a scoped patch plan.
Prompt starter
Review the attached code for [goal]. Trace the request end to end, list findings by severity with file evidence, then propose the smallest safe patch and focused tests.
3
Video and mixed-media review
Combine frames, audio, PDFs, and notes into one timeline or evidence-led review.
Prompt starter
Review the attached media as one project. Build a timestamped issue list, connect each issue to visible or audible evidence, and propose an edit plan.
