# Claude Code cloud sessions now set up a repo's environment themselves and store API keys Claude cannot see

Anthropic said on Nov 6, 2026 that Claude Code cloud sessions (Pro, Max, Ultra) work out which dependencies, network access and API keys a repo needs, then save the environment for next time; keys are stored so that 'Claude never sees them'.

## Key facts
- Plans: Pro, Max and Ultra
- Environment saved for reuse across sessions
- Announcement: @ClaudeDevs, ~640k views
- Same week: Apiiro reported 1,122 public GitHub files exposing passwords via Claude Code's 'Don't ask again' permission settings (HN 434 pts)

## What happened

Announced only on X. Quote: "API keys are saved securely, so Claude never sees them."
