Description

I notice a significant difference in behavior and outcomes when using Opus 4.5 through Antigravity vs through Anthropic. The same for when I used Opus 4.5 via OpenRouter.

I don't know, but I suspect that the ANTHROPIC.txt is only being used for the Anthropic hosted models.

I couldn't find a way to force Opencode to use the ANTHROPIC.txt prompt for specific providers/model combinations. If that doesn't exist it would be great to have that option.

This issue might be a duplicate of existing issues. Please check:

  • #3195: Dynamic system prompts for custom agents
  • #5728: [FEATURE]: Ability to override tool prompts - create model toolsets
  • #1891: Per-Model Instructions

These issues discuss similar functionality for allowing custom or model-specific system prompts and configuration. Feel free to ignore if your specific case about model providers (Antigravity, OpenRouter, etc.) is not addressed by these.
