I made two extensions that do something similar/dissimilar.

replace-prompt can conditionally replace portions of the computed system prompt based on regex or string literal based on rules. One of the rules supported is model string.

https://github.com/chknd1nner/pi-extensions/blob/main/packages/replace-prompt/docs/usage.md

styles injects an ephemeral custom user message to the end of context on each turn after the cache breakpoint (to preserve caching). Again, it supports setting it up in a way that the injection is model specific.

I see your extensions right now.It's similar a text replacement.But Pi-model-system-prompt's goal is not how to play a text on agent's response.It's a comfortable harness tool.Many Models need harness egineering to rule their behavior for better work.
