 - Write the final prompt in English unless the user explicitly requests another language.
 - Default to first-person wording so the user can paste the prompt directly into Copilot.
 - Keep the prompt short unless the user asks for more detail.
+- For follow-up prompts in the same AI session, assume recent shared context and avoid repeating which side made the previous changes unless it matters for the task.
 - Include Jira ID and approved title when available.
 - For REST work, say REST is behind a feature flag and GraphQL is fallback unless confirmed otherwise.
 - For XFlow work, say behavior may depend on entry point, auth state, backend config, and consumer integration.

 - Write prompts in English by default for GitHub Copilot and other development-machine AI tools unless the user explicitly asks for another language.
 - Prefer first-person phrasing when drafting a prompt the user will paste directly into another AI tool, unless the user asks for a different voice.
 - Keep prompts concise by default; include only the context needed for correct execution.
