GitHub Copilot produces incorrect business logic code requiring extensive rework

8

Copilot fails to correctly implement even simple business logic, requiring four+ iterations to get right. This forces developers to manually fix the same errors repeatedly, compounded by billing that penalizes retries.

GitHub Copilot inconsistently applies framework-specific instructions

7

Copilot fails to consistently follow framework-specific instruction files provided by developers. Instructions are acknowledged but then ignored, requiring developers to repeat the same context multiple times across requests.

GitHub Copilot cannot reliably read VS Code problem diagnostics

6

Copilot claims to read errors from VS Code's Problems tab but consistently fails to do so. Developers must manually copy and paste error messages to get Copilot to address them.

GitHub Copilot VS Code extension degrades with each update despite promising release notes

6

Each new VS Code release promises improvements to Copilot integration, but in practice the extension often becomes worse than the previous version, frustrating developers who expect incremental progress.

GitHub Copilot lacks intelligent request routing to appropriate models

6

Developers must manually switch between Copilot models (ChatGPT, Claude, etc.) for different task types, often forgetting to optimize cost. There is no smart triage system to route simple questions to cheaper models and complex requests to premium models.
