What's Wrong?

Context Drift & Destructive Rewriting

Across multiple diverse projects, the model is exhibiting a consistent failure to maintain established architectural rules. There is a critical breakdown in Instruction Persistence, where the model successfully executes a complex task at the start but regressively destroys that progress during subsequent minor iterations.

  1. Core Technical Failures Destructive Full-File Rewrites: Instead of performing targeted edits, the model frequently attempts "complete code overhauls" that wipe out stabilized features and logic not directly related to the current prompt.

    Amnesiac Regressions: The model "forgets" foundational constraints (like custom UI positioning, specific naming conventions, or unique navigation rules) that were explicitly defined in the project memory.

    "Junk Drawer" Logic: The model displays a tendency to consolidate independent system modules into single containers, breaking spatial and logical separation established in earlier prompts.

    Generic Pattern Preference: The model repeatedly ignores specific, high-fidelity design mandates in favor of "standard/safe" web or software patterns (like reverting custom 3D logic to 2D UI dashboards).

  2. Functional Impact Broken State Management: The model loses track of how different tiers or screens of an application interact, often resulting in "hollow" UI elements with no underlying logic.

    Input/Interaction Deadlocks: Navigation logic (e.g., custom keyboard shortcuts or click-events) is frequently overwritten by default browser/OS behaviors during unrelated updates.

    Instruction Timeout: Attempting to force the model to fix these systemic regressions often leads to "API Stream Idle Timeouts" as it struggles to reconcile its generic defaults with the user's complex instructions.

In other words, you are wasting user's money and time. Hope you can fix the problems. Thank you

extent analysis

TL;DR

The model's context drift and destructive rewriting issues may be mitigated by refining user prompts to emphasize instruction persistence and architectural rules.

Guidance

  • Review and refine user prompts to ensure they explicitly define and reinforce established architectural rules and constraints.
  • Consider breaking down complex tasks into smaller, targeted edits to reduce the model's tendency for full-file rewrites.
  • Investigate the use of custom templates or presets to help the model remember foundational constraints and design mandates.
  • Evaluate the model's training data and fine-tuning process to identify potential biases towards generic patterns and standard web or software patterns.

Example

No code snippet is provided due to the lack of specific technical details.

Notes

The issue's complexity and lack of specific technical details limit the provision of a comprehensive solution. Further investigation and experimentation are necessary to fully address the model's context drift and destructive rewriting issues.

Recommendation

Apply workaround: Refine user prompts and investigate custom templates or presets to help the model remember foundational constraints and design mandates. This approach may help mitigate the model's context drift and destructive rewriting issues, although a more comprehensive solution may require additional research and development.
