Copilot prompts are in the extension, they make the system_prompt field you send in the API request to an LLM The underlying models have various guardrails and alignments that you cannot work around trivially For Copilot, you can look at the code on GitHub, it is JSX based, which is interesting, they pass context budget info around For Claude Code, and many others, you can find the extracted prompts online At this point, they are all dynamically generated from fragments and contextual data (like what files or language you're working with)
