This change extends the Rust shell development skill guide with an "AI Collaboration & Workflow" section that captures lessons from recent interactions, including how to modify code with better context, communicate intentions more proactively, and interpret user feedback more accurately. Although it’s a documentation-only update, it strengthens the team’s working conventions around AI-assisted development and should help future edits be more aligned and transparent. The practical effect is smoother collaboration and fewer mismatches during iterative development.
