About this skill
TDD Skill
When to use this skill
- new features that can be unit tested
- bug fixes (always add a regression test if practical)
- refactors (protect behavior with tests first)
Rules
- Prefer red -> green -> refactor.
- If tests are hard, still add verification: minimal repro script, integration test, or clear manual steps.
- Keep tests focused: one behavior per test where possible.
- Name tests by behavior, not implementation details.
Process
- Define the behavior change (what should be true after).
- Write/adjust a test to capture it (make it fail first if possible).
- Implement the minimal change to pass.
- Refactor if needed (keep passing).
- Run the relevant test suite + any linters.
Output requirements
When you change code, include:
- what tests you added/changed
- how to run them
- what they prove

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
