Explain this error in plain language: what it means, the most common causes, and how to fix it. Give me the 2–3 most likely fixes in order of probability. Error: [PASTE ERROR + relevant code]

I need to build [FEATURE / THING]. Before I write any code, help me think it through: ask me any clarifying questions first, then outline an approach, the main components, edge cases to handle, and a suggested order to build it in. Don't write the code yet.

The code below is slow / resource-heavy. Identify the bottleneck, explain why it's costly (time/space complexity), and give me an optimized version. Note the tradeoffs of your approach. Code: [PASTE]

Add clear docstrings and comments to the code below. Document what each function does, its parameters, and return value. Comment only the non-obvious logic — don't state the obvious. Keep the code itself unchanged. Code: [PASTE]

I want to build [FEATURE] in [STACK]. Ask clarifying questions, then propose an approach and components.

Help me implement [COMPONENT], explaining key decisions.

Give me the file/function structure and stubs for that approach.

Review the finished feature like a senior engineer and list must-fixes.

Write unit tests covering happy path and edge cases.
