A repository team wants Copilot cloud agent to remember stable build rules, apply frontend-specific guidance only to React files, and fetch live feature-flag state from an internal service when needed. Evaluate the following statements. 1. Stable build rules fit repository custom instructions better than short-term prompt context. 2. The React guidance is path-specific context for matching files, not global memory for every file. 3. Live feature-flag state should be copied into custom instructions so the agent can fetch it automatically.
