Claude Code 4.6 regression: forgets project deployment context

Description

After upgrading to Claude Opus 4.6, Claude Code repeatedly forgets that a project deploys to Vercel via GitHub push. It kept suggesting local server restarts and browser cache clears instead of committing and pushing changes, wasting multiple conversation turns.

This did not happen on previous model versions — the deployment context was retained throughout the session.

Steps to Reproduce

1. Work on a Vercel-deployed project (Flask app, auto-deploys from main)
2. Make file changes and ask Claude to implement them
3. Claude suggests restarting local server / hard refresh instead of pushing to deploy
4. Even after being told it's a Vercel app, Claude forgets on the next interaction

Expected Behavior

Claude should retain project deployment context within a session and not repeatedly suggest local-only solutions for deployed apps.

Environment
