claude-code - 💡(How to fix) Fix Safety: /resume shows sessions from all directories — risk of modifying wrong project [2 comments, 2 participants]

Problem

The /resume command shows sessions from all projects/directories by default, not just the current working directory. A user in project B can accidentally resume a session from project A, causing the agent to read/modify files in the wrong codebase.

This is a safety issue, not just a UX inconvenience — the resumed agent retains the original session's context but operates in the current terminal's working directory.

Steps to reproduce

1. Start a Claude Code session in /path/to/project-a, do some work, exit
2. cd /path/to/project-b
3. Start Claude Code, type /resume
4. The picker shows sessions from project-a and all other directories by default
5. Selecting a project-a session resumes it while the working directory is project-b

Current behavior

The /resume picker defaults to showing all sessions across all directories. Filtering controls exist in the footer:

• Ctrl+A — narrow to current directory only
• Ctrl+B — filter to current branch
• Ctrl+W — filter to current worktree

However, these filters do not persist between invocations — every /resume resets to showing everything.

Expected behavior

• Default to current directory only — the safe default is scoped, not global
• Ctrl+A (or similar) to expand to all directories when intentionally needed
• Persist the user's filter choice across invocations, or at minimum default to the safe option

The current default inverts the safety model: the dangerous action (cross-directory resume) is the default, and the safe action requires an extra keystroke every time.

Environment

• Claude Code CLI
• Discovered while running multiple agent sessions across different project directories
