Suggestions for improving the efficiency of code generated by using copilot

Hi GitHub Copilot team,

I was using Copilot for code generation and noticed a couple of recurring challenges — sometimes the generated code becomes inefficient or repetitive, and occasionally it introduces minor inconsistencies or unused variables when modifying existing features.

I have a suggestion that could make Copilot’s code generation more efficient, consistent, and secure, especially in larger projects.

What if Copilot could maintain a few structured internal documents alongside the project, such as:

1. Feature Map – listing all features in the project, indicating which are done, in progress, or planned.

2. Variable Registry – tracking all major variables, their purpose, and where they’re used.

3. Function Registry – explaining each function’s purpose, inputs/outputs, and usage locations.

When a user asks to add or change a feature, Copilot could refer to these three internal maps instead of re-analyzing the entire codebase. This would help it quickly decide whether to:
Add a new function, or Extend an existing one safely.

If the user already knows which function to modify, they could simply mention it — making Copilot’s response faster, more context-aware, and cleaner.

Overall, this could:
Reduce inefficiency and redundancy in generated code,
Improve code consistency and structure, and
Enhance security by keeping track of variable/function relationships.

This system could work as an internal documentation layer that updates automatically as the project evolves. I think this would help bridge the gap between AI assistance and real-world software engineering workflows.
