test-claude-resume-sid

Yes, Claude Code's --resume flag preserves the original session ID across multiple processes. This Skill tests SID preservation to confirm session identity persists, preventing unexpected behavior when resuming sessions.

You need this session ID verification to debug SID-to-PID mapping issues in agent management servers. It validates that resuming a session maintains identity across processes, which is essential before implementing complex agent orchestration.

You can test Claude Code session management by running the automated test script included in the scripts directory. It uses tmux to validate that the session ID is maintained when using the resume flag.

This Skill is specifically designed for debugging agent management systems and confirming session identity persistence. It checks if the --resume flag maintains the original SID or forks a new one, ensuring orchestration readiness.

The best way to check session continuity is by running an automated test script that validates SID preservation. This confirms that resuming a Claude session maintains the original session ID across multiple processes.

The primary limitation is the dependency on tmux, which must be installed in your environment. The Skill focuses strictly on validating session ID preservation and does not perform broader agent orchestration tasks.
